ISO 12944 – The Corrosive Environment

ISO 12944 – The Corrosive Environment

Categorising corrosivity by type of environment

In a recent article, we introduced you to ISO 12944, the internationally recognised standard that provides the guidelines for the use of paint and coatings to protect assets from corrosion. The second part of the standard discusses the corrosive environment. This article introduces you to this part of ISO 12944 and the changes that were introduced in the latest revision in 2018.

What is the corrosive environment?

The corrosive environment describes the environment in which the asset to be protected is situated. There are many variables within corrosive environments. Combined, these determine how corrosive the environment is, and therefore the types of protective paint systems that are needed to help prevent corrosion (covered in part 5 of the standard).

When discussing the corrosive environment, two terms are used:

  • The local environment, which describes the atmospheric conditions around a particular component
  • The micro-environment, which is the environment at the interface between an element of a structure and the local environment

The environmental factors that determine an environment’s corrosivity are:

  • Climate (the weather, which is established by reference to historical data)
  • Atmosphere (the gases – including aerosols and particles – that surround the asset to be protected against corrosion)

The classification of environments considers temperature, relative humidity, and the time of wetness (the length of time that the metal surface is likely to be covered in a film of electrolyte that can cause atmospheric corrosion). In brief, atmospheric corrosivity calculations are made by summing the hours when the relative humidity is above 80% and the temperature is above 0°C.

Corrosivity is dependent on the corrosive agents present in the environment, especially gases such as sulphur dioxide, and salts such as chlorides and sulphates.

Types of corrosive atmospheres

When specifying the protective coatings that should be used on assets, ISO 12944 considers the type of atmosphere in which the asset is located, and categorises these from rural (away from corrosive agents such as sulphur dioxide) through to marine (where airborne salts are present).

If the asset is indoors, the potential for corrosion is usually lower because atmospheric pollutants are usually reduced. However, if the indoor asset is poorly ventilated or suffers from high humidity, then this increases the potential for condensation and, therefore, corrosion.

The categories of corrosivity are taken from a separate standard, ISO 9223;2012 – “Corrosion of metals and alloys — Corrosivity of atmospheres — Classification, determination and estimation”.

The scientific method for determining corrosion rate is determined by calculating the rate of metal loss on sample coupons (mild steel or galvanized steel) that are placed in the given environment. In practice, this is rarely performed for the determination of corrosivity for a paint specification. The corrosivity is determined by an objective estimation of the general description of the environment based on the descriptions in the standard, and the professional assessment by all parties involved in drawing up the corrosion protection specification.

Location of asset and corrosivity

When protecting assets from corrosion, ISO 12944 also considers whether the asset is in soil or water. Where assets are only partially buried in soil or partly immersed in water, the corrosion is usually localised to where the rate of corrosion can be highest.

Corrosion of assets that are immersed in water depends upon the type of water (fresh, brackish, or salt), how much oxygen is present in the water, the water’s temperature, and the substances that are dissolved in the water. There are three different ‘zones’ for corrosion, transitioning from the splash zone (wetted by spray), through intermediate (where wetting is fluctuating), to fully immersed.

Corrosion of those assets that are buried in soil depends on factors that include the minerals present in the soil and its water and oxygen content. The type of protection coating needed for buried-in-soil assets may differ along the length of the asset, because it is more likely that they will be buried in different soils – in such cases, the rate and severity of corrosion will differ.

Changes to ISO 12944 in 2018

There are three major changes in environmental categorisation as described in ISO 12944. There are now five environmental categories for onshore assets, ranging from C1 (very low corrosivity, typically in a climate-controlled indoor environment) to C5 (very high corrosivity environments, such as a coastal refinery).

A new environmental category has been introduced – the CX category, which covers offshore environments. This category is now covered in detail in a new section of the standard – part 9.

The IM categories, covering immersed assets, now include a new category (IM4) that deals with immersed assets with cathodic protection.

Key takeaways

In summary, the environment in which an asset is sited has a significant effect on the potential for it to corrode, and therefore the design of corrosion prevention system used. Factors that determine corrosivity of the environment include temperature, humidity, condensation, and corrosive pollutants in the atmosphere.

In classifying corrosion environments, ISO provides a reliable guide for the design, implementation and maintenance of structures and corrosion prevention systems and the applicable characteristics of paints and coatings that may be used.

In our next article in this series covering ISO 12944, we examine the section of the standard that deals with steel structure design.

Corrosion Protection – A Week of Webinars

Corrosion Protection – A Week of Webinars

Bringing the corrosion conversation to you

After the huge success of the week of webinars to combat corrosion, the Marine Corrosion Forum and the Institute of Corrosion are collaborating once more to bring five more exceptional webinars into your homes and places of work, as we discuss some of today’s corrosion protection issues.

These webinars, presented by some of the world’s leading corrosion experts, will follow the same format as before: one each day for five days, each presented at a time to allow as many people as possible to attend. You’ll need to be quick to register, though – there is a limit of 200 people for each webinar, and places will be allotted on a first-come-first-served basis.

Online delegates to this series of webinars are in for a real treat – with a big focus on offshore wind and other renewables, and a ‘dip-in/dip-out’ timetable that allows you to attend the webinars individually without needing to commit to attending all five. Oh, and registration for these corrosion protection webinars is free.

Before a summary of each webinar, let’s introduce the presenters – it’s quite a line-up.

After a short period working with standard products Chris was engaged in a high-profile project for Mechanical Connectors for Deep Water Repairs which lasted 2 years. After that Chris was a leading figure on the engineering team developing the new MORGRIP CLiP Connectors which are the subject of today’s presentation.

The agenda for this week of webinars

Without further ado, let’s take a glimpse at each of the webinars. Each will be a one-hour presentation by the subject expert. A Q&A session via the chat box immediately follows the presentation.

Improving the Corrosion Resistance of Duplex Steel Welds (Dr Roger Francis)

Monday 6th July 2020, 12pm BST

Register for this webinar here

Modern duplex stainless steels have been in common use since the early 1980s, and how to weld these alloys satisfactorily is well understood. Despite this, corrosion failures of welds still occur. This talk will discuss the important parameters to produce satisfactory welds in duplex stainless steels.  There are further things that can be done to improve the corrosion performance of duplex welds, and these are discussed along with test data. It is important that testing over and above that in ASME IX is carried out on duplex weld Procedure Qualification Records (PQRs) and some suitable tests are proposed. The corrosion resistance of welds and parent metal to different sorts of corrosion will be discussed.

Hot Corrosion Mechanisms for Gas Turbines (Dr Adnan Syed)

Tuesday 7th July 2020, 12pm BST

Register for this webinar here

Hot corrosion mechanisms were first proposed more than half a century ago, but we are still learning about them and they continue to be a focus for manufacturers of aero and industrial gas turbines.

The understanding of corrosive salt and target alloys are both crucial topics to enable improved mechanisms. Corrosion mechanisms vary due to the composition of the alloys and deposit salt chemistries.

The concept of acid and basic flux on the alloy surface due to induced deposits on the alloy’s surface is also well defined; however, further investigation is still required.

Along with laboratory corrosion experiments, the use of thermodynamic software is a key tool to help identify the likely phases formed, which in turn enables a better understanding of the mechanisms involved.

The talk will include the possible hot corrosion mechanisms occurring in the gas turbine combustion environment, and support some of the challenges the industry is facing in its understanding and managing of turbine component degradation. The talk will also present the laboratory setup for hot corrosion testing and techniques used for evaluation of material performance.

Improvements of the DNVGL-RP-416 and DNVGL-RP-B401 – Upcoming Revisions (Lars Lichtenstein)

Wednesday 8th July 2020, 12pm BST

Register for this webinar here

This is a must-attend webinar for those working in the wind turbine industry. You’ll receive the inside track on material selection for bolts and stainless steel, and the boundary conditions that should be considered.

The recommended practices issued by DNV GL on corrosion protection for wind turbines are being reviewed internally. Learn what the items and considerations under review are, and become updated on how the process of review is used to address and improve the overall quality of corrosion protection for offshore wind.

The current key DNV GL documents for corrosion mitigation and CP in this sector are DNVGL-RP-0416 and DNVGL-RP-B401. Formally, DNVGL-RP-0416 is issued from Renewables Certification, part of the energy business, while DNVGL-RP-B401 is owned by the oil and gas business. Therefore, this presentation will mainly deal with the items and considerations being dealt with for the revision of DNVGL-RP-0416, but relevant topics in relation to DNVGL-RP-B401 can also be addressed and discussed.

Since 2016, when DNVGL-RP-0416 was first published, these recommendations were applied to numerous offshore wind projects. We have been part of the certification process for many of these projects and could gain experience and feedback on the content we have issued. Generally, there has been positive feedback, but some guidance lacks sufficient detail. Some of these areas need to be addressed to improve the overall quality of corrosion protection for offshore wind.

Several relevant standards have been revised since 2016 (e.g. ISO 12944 or ISO 2063), new standards like VGB/BAW have been introduced, and new ISO standards are currently being written in several working groups. Improvement of the guidance given is needed and possible. We want to address the most relevant items with new revisions of our RPs.

This seminar will provide more guidance on the useful coating lifetime as introduced in DNV-OS-J101:2011 for the first time, and the relation with fatigue calculation and surface preparation. What level of quality is needed at the end of the lifetime? How much effort shall be put into inspection and repair of 15-year-old+ coating systems? You will gain insight on material selection for bolts and stainless steel, as well as what boundary conditions should be considered. This seminar will also study the issue of coating breakdown factors with regards to CP system calculation and on currency drain of buried structures. The revisions of the documents are not yet finished, and therefore input from this event will be able to influence the development of future recommended practices.

Cathodic Protection of Offshore Renewable Energy Infrastructure (Brian Wyatt)

Thursday 9th July 2020, 12pm BST

Register for this webinar here

External surfaces of offshore structures, including offshore wind turbine foundations and tidal/wave energy structures are routinely protected from corrosion by cathodic protection [CP] using aluminium alloy galvanic anodes. Design codes for this are provided by several sources; the most commonly used for offshore wind applications being DNVGL-RP-B401.

These codes have been produced primarily for jacket structures used in deep water for oil and gas developments. They are inadequate for structures required for offshore energy infrastructure such as offshore wind turbine monopile [MP] foundations, tidal turbines, or wave generators – all of which need to be installed in near-shore shallow water environments. For these conditions, there are special considerations over and above those defined in these codes, notably the impacts of higher tidal flow, a greater proportion of the shallow structures being in the tidal zone and of wave action. All result in high levels of oxygenation at the steel/water interface which demand more robust CP designs, both in mechanical and electrochemical terms. The nature of the support structures, and limited scope for lower-cost onshore anode installation, also lead to challenges to uniform anode distribution, particularly on MPs.

Although DNV GL has addressed some of these issues in its DNVGL-RP-0416, written specifically for offshore wind applications, it has not addressed all of the environment issues, and the requirements remain largely biased towards the use of RP-B401 for CP design.

A new International Standard, EN ISO 24656 ‘Cathodic Protection of Offshore Wind Turbine Structures’ is under development to address these issues more fully. It will soon be published for public comment. It will reflect a significant change in the design process for cathodic protection, to reflect the particulars of offshore wind foundations and their environments.

This seminar concentrates on these additional considerations for the design of external CP for near-shore offshore energy infrastructure. It also, briefly, discusses the special and different requirements for internal CP of wind turbine monopiles.

Use of CRAs in Subsea Pipelines and Repair of Clad Pipeline Connections (Andrew Woodward and Chris Matthews)

Friday 10th July 2020, 12pm BST

Register for this webinar here

Since 2009 the MORGRIP team has been engaged with major operators to develop a mechanical connector solution specifically designed to meet the unique challenges of Clad and Lined Pipeline systems. A traditional mechanical connector seals on the outer diameter of the pipe and is used as an alternative to welding for straight cut pipe ends. For a clad or lined pipe this type of connector does not adequately protect the pipe end and parent pipe from the corrosive attack of the aggressive sour line media.

The CLiP Connector was developed over 2 phases of a Joint Industry Project part funded by Chevron and Woodside. The aim of the JIP was to take the existing MORGRIP connector technology and integrate a mechanism to protect the exposed end of a clad pipeline from the aggressive line media after installation.

The seal takes advantage of the corrosion resistant and ductile properties of Alloy 625 when subjected to specially controlled heat treatment as well as extensive testing and track record of graphite in order to create a seal module that conforms to NACE MR0175 / ISO15156-3. The seal forms around all pipeline manufacturing tolerances and even localised irregularities such as internal weld seams. The seal can be easily integrated into existing mechanical connector configurations and is able to be adapted for both diver installed and remote repairs.

The technology qualification was completed to DNVGL-RP-A203 through a combination of analysis, 3rd party material testing, component testing and culminating in full scale testing of a production unit. This resulted in the award of a DNVGL Type approval for the product range in accordance with the requirement of DNVGL-ST-F101 for submarine pipelines and DNVGL-RP-F113 recommended practice for pipeline repair.

ISO 12944 – Are You Meeting the Latest Standards in Corrosion Protection?

ISO 12944 – Are You Meeting the Latest Standards in Corrosion Protection?

Corrosion protection of steel structures by protective paint systems

First introduced as an eight-part standard in 1998, ISO 12944 was updated for the second time in 2018 with some significant changes and additions. Setting standards for coatings for steel structures in atmospheric, immersed, and buried environments, ISO 12944 now has nine parts. This article introduces the standard, answering the key questions that professionals in corrosion prevention ask about it.

What is ISO 12944?

ISO 12944 is a globally recognised standard that lays out the rules and guidelines for the protection of assets from corrosion by use of coating systems and paint. Having been introduced in 1998, it was updated in 2007 and revised a second time in 2018.

The standard covers paint and coatings for steel structures in atmospheric, immersed, and buried environments. It does not cover coatings for concrete, non-metallic substrates, high-temperature surfaces, chemical immersion, and other uses.

The standard covers three factors when dealing with protecting steel structures from corrosion:

1.      Corrosivity

The potential of the environment to cause corrosion. To achieve this, the standard classifies the environment into categories that are rated on their ability to corrode unprotected steel.

2.      Durability

The expected lifetime of the coating system until its first major maintenance. The standard also emphasises that inspection and minor maintenance should be expected throughout the lifetime of the structure.

3.      Coating system specifications

Based on the corrosivity of the environment and the durability of corrosion protection needed, ISO 12944 acts as a guide to selecting the coating system required for the steel structure to be protected.

Who should use ISO 12944?

The standard is designed for use by all those who have some experience and knowledge of either specifying, manufacturing or using paint and coatings to protect steel structures against corrosion in different environments.

Those who need to adhere to ISO 12944 include asset owners, construction companies, engineering companies, corrosion consultants, paint manufacturers and painting companies. Individuals who must work to the standard include:

What standards does ISO 12944 detail?

Within the nine parts of ISO 12944, standards are provided across the following themes:

1.      Corrosivity, environments, and categories (parts 2 and 9)

Environments are classified across several categories, with recommendations that cover atmospheric exposure, fresh and seawater immersion, and buried surfaces.

2.      Design considerations (part 3)

The standards covered here deal with the basic criteria for the design of steel structures that are to be coated to avoid premature corrosion of the substrate.

3.      Surface preparation (part 4)

Standards for the preparation of surfaces are given, with the objective of minimising the risk of premature failure of the coating system used.

4.      Protective paint systems (part 5)

The paint system used will depend upon the environment in which it is to be used and the intended durability, and ISO 12944 covers this.

5.      Lab testing methods (part 6)

Testing methods and conditions are detailed in ISO 12944. Testing should help users decide which coating system should be used, and so standardises testing to enable more accurate and comparable testing that acts as a guide (but not exact information) for determination of durability within a given environment.

6.      Execution and supervision of paint work (part 7)

As you would expect, the standard also deals with how coating of steel structures is executed and supervised, either on-site or in the workshop. The standard includes pre-treatment and paint application methods.

7.      Development of specifications (part 8)

Part 8 of the standard deals with development of specifications for the protection of steel structures from corrosion by using coating systems. These standards also apply to the protection of individual components, and cover new work and maintenance both on-site and in the workshop.

What changed in the latest revision?

The major changes in the 2018 revision were:

  • The Introduction of part 9, which discusses offshore environments and establishes a new ‘CX’ category.
  • Alterations to the categorisation of onshore environments.
  • The introduction of a new category for coatings used in conjunction with cathodic protection in seawater and brackish water environments.
  • Changes to durability standards, and the introduction of a new category for very long durability of more than 25 years.
  • Changes to minimum dry film thicknesses and the minimum number of coats to be used. These specifications have been made mandatory to bring a halt to the ‘race to the bottom’ in which paint manufacturers were producing increasingly thin layers to compete on cost.
  • Standards for testing have been updated, with new cyclical testing recommendations to better replicate on-site conditions.

The standard also recognises the need to remain innovative. It states that new technologies and innovative products can be accepted, but the manufacturer must demonstrate suitability by either reference to third-party product testing or a demonstrable track record.

In future articles, we’ll take a closer look at the changes and updates in ISO 12944. You can also read about them in Corrosion Management Magazine.

The Institute of Corrosion Coating and Inspection Training Courses – presented by IMechE Argyll Ruane and Corrodere – will help ensure your painters and inspectors work to the latest industry standards and benefit from new technology and innovative approaches.

Corrosion Courses Opening Again

Corrosion Courses Opening Again

Is it time to boost your career with training and development (T&D) in corrosion?

It’s been a tough period for training and development in the corrosion prevention industry. Because of the coronavirus lockdown, it was necessary to move a lot of corrosion T&D initiatives online. Here at ICorr, we adjusted our training and development initiatives as fast as we could, to ensure that as few people as possible were negatively affected as possible.

In a recent blog, we described some of these initiatives, including:

We can now give you more great news. Another of our approved training partners, IMechE Argyll Ruane, is now open for business and once more delivering Institute of Corrosion courses designed to address corrosion issues facing various industries.

Back in the classroom – with a difference

On 21st May, 2020, IMechE Argyll Ruane was able to announce that it is fully back up and running, and that those wishing to book onto its Institute of Corrosion courses can do so now.

These on-site courses, held at their exceptional facility at the Sheffield Business Park, will now benefit from a range of measures to ensure your health and safety as we move to a new normal economy. Training processes have been adapted, and there will be PPE in place to aid student and staff safety as well as social distancing methods. It’s on-site delivery of training with a COVID-19 twist.

Though there will be many visible differences to how training is delivered, which may include distance learning for some course material where possible and appropriate, one thing has not altered – you’ll still benefit from trainers with years of experience in the field and in delivering exciting training experiences. You can be certain that the training you receive will be accompanied by real-world examples.

The benefits of being ‘in the classroom’

While the benefits of online training have become apparent to many, there are many benefits only available through on-site training. These include:

  • The human touch – a quality that is, thus far, impossible to replicate online. The interaction that is possible between students and staff in the classroom helps all to learn. You’ll learn from questions asked by others, and the experience of all participating in the training course.
  • A classroom setting – this also helps you to hone soft skills (such as interpersonal skills) and develop your professional network more effectively.
  • Health and safety measures in place – you’ll be learning in a safe, clean environment away from the pressures of work or the interruptions at home.

A wide range of training and development in corrosion prevention

All the ICorr training and development opportunities lead you toward industry standards with internationally accredited and recognised courses and certification that help to accelerate careers in your industrial setting.

Aspects of corrosion prevention that are covered by these courses include:

Re-certifications are available online for:

  • Painting Inspector Level 1
  • Painting Inspector Level 2
  • Insulation Inspector
  • Passive Fire Protection Inspector
  • Pipeline Coatings Inspector Level 2
  • Hot Dip Galvanising Inspector

Is it time to give your career a boost through T&D?

Training is critical for your career. It helps improve your skills and abilities, and makes you more attractive to current and potential employers. Developing your value in your professional capacity is a choice that helps you in all economic conditions.

Your training and development also benefit your current employer. You’ll perform your job more effectively, improve productivity, and be more satisfied in your role (and less likely to look for another job elsewhere). Happy employees are great advertisements for any business, and make it easier to attract talented new hires.

The answer to the question “Is it time to give your career a boost through T&D?” is always yes – whether through online or on-site methods.
