SSPC

SSPC, The Society for Protective Coatings, has revised one guide and one joint standard practice

SSPC-PA Guide 11, Protecting Edges, Crevices, and Irregular Steel Surfaces by Stripe Coating.

The 2020 revision adds definitions for some previously undefined terms and provides guidance to specifiers for

• Determining when the stripe coat is applied (before or after a full-coat application)

• Determining suitability of a coating for use as a stripe coat (cumulative DFT, compatibility)

• Preparing outside corners and edges for application of a stripe coat

• Treatment of flame-cut edges prior to application of stripe coat.
Additional changes Include, examples of specification language in a non-mandatory appendix, and illustrations of areas that may be considered for stripe coating.

This guide discusses the technique called “stripe coating” or “striping” as a way of providing extra corrosion protection measures on edges, outside corners, crevices, bolt heads, welds, and other irregular

steel geometries, including optional techniques that can be used to improve coating performance. It is not intended to provide all-encompassing guidance but rather offer options when preparing a project specification. The engineer should evaluate and address details on a project-specific basis.

SSPC-CPC 1/NACE SP21412 Corrosion Prevention and Control Planning

This standard defines the key elements/composition of what corrosion prevention and control planning encompasses for design, manufacturing, construction, operation and sustainability of products and facilities. Although intended for use by US Federal agencies, it may be applied to other industries where appropriate. It provides a standardised framework for a supplier’s plan to control corrosion on products and facilities.

The 2020 revision includes:

• Adding two new key elements in the body of the standard that provide critical and desired characteristics for each element in the appendix.

• The addition of an evaluation methodology on how to assess corrosion prevention and control (CPC) planning of a programme/project as a second appendices.

• Now provides the key elements for performing CPC planning, desirable characteristics of each element, and a method for determining the overall adequacy of CPC planning for a given program or projects.
