The second of three volumes in the Inspection Instruments for the Pipeline Coatings Industry E-Book Series, “Verifying the Quality of Coating Application” is written by KTA COO, William D. Corbett. It provides information on the proper use of test instruments for verifying the quality of the application of protective coatings. It is applicable to new […]
Part 1: Specifications Simplified Independent of the type of coating project, a properly prepared specification is a key component to its success. A coatings specification describes the project and the objective of the coating system. It also describes the surface preparation requirements, materials required to complete the work, the intended appearance of the completed work,
Specifying Coatings Read More »
One of the tasks for a specifier when selecting coating systems is to properly and thoroughly identify the prevailing service environment for existing structures/facilities, or the anticipated service environment for new structures or facilities. Stated more simply, once the coating system is installed, what will it be subjected to, under both normal and upset operating

Introduction Surface preparation prior to coating installation is generally composed of two goals: achieving the minimum specified surface cleanliness, and achieving the specified range of surface profile (surface roughness). While these goals may be achieved in a single operation (e.g., by abrasive blast cleaning) or two separate operations (e.g., by water jetting or chemical stripping,
Background SSPC: The Society for Protective Coatings, NACE International and other trade organizations have volunteer technical committees made up of subject matter experts that develop consensus standards that are drafted, balloted, approved and published. Development of a new standard can take as short as 3 years and as long as 5-7 years, depending on the

The Issue There are two questions that can arise when performing in-process quality checks of surface preparation and coating application processes, or when evaluating the performance of a coating system already in service. These include, “How do I perform the tests,” and “What is the frequency required to ensure my test data is representative?” The
Frequency of Measurements in the Coatings Industry Read More »
Introduction Most industrial and marine protective coatings rely on a mechanical bond to the substrate to remain attached while in service. This bond is generally provided by a surface profile or anchor pattern that is imparted into the surface prior to application of the coating system and effectively increases the surface area of the substrate

“Coating thickness shall be measured in accordance with SSPC: The Society for Protective Coatings Paint Application Standard No. 2 (SSPC-PA 2)” is a simple enough statement, yet this common specification requirement is often misinterpreted, or regarded as a document that simply states how to measure paint thickness, something we already profess to know how to
