SSPC- PA 2 Appendix 7

Using SSPC-PA 2 Appendix 7 to Determine Conformance to Dry Coating Thickness Requirements on Steel Pipeline Exterior Surfaces

Pipelines have become one of the most efficient means of transporting liquids and gas safely from point of origin to point of use.  According to the Bureau of Transportation Statistics, the United States has over 218,387 miles of oil pipelines and over 1,626,959 miles of gas pipelines. The American Society of Civil Engineers (ASCE) indicates …

Large-Diameter Cooling Water Pipe and Penstocks: Selecting and Applying Linings

As Seen in JPCL Magazine, August 2019 The installation of linings in large-diameter cooling pipes and penstocks is a major investment for hydroelectric and other power plants. The application should be performed in an expedient manner to minimize outage time and should last for many years—20 or more—without the need for maintenance painting. The latter …

One-sided Cell Exposure Testing: For What Purpose?

Coatings technology for lining of tanks, piping, and vessels has rapidly advanced in recent years. Extremely tightly-crosslinked coatings are relatively impermeable, and specialty resins and pigments are formulated into linings specifically to perform in extreme environments. Why, then, is it critical to further scrutinize these lining systems by subjecting them to conceivably unrealistic temperature gradients …

Holiday Detection and Dielectric Strength Issues

Introduction When applying coating system to structures such as bridges, tanks, and pipelines the main goal is to apply a continuous film to help prevent structural deterioration throughout the life of the structure. Unaddressed discontinuities can result in undercutting corrosion of the substrate, where the integrity of the structure could be prematurely compromised. This article …

Evaluating a Coating’s Resistance to Cathodic Disbondment – Guidance on Selection of Test Methods

Installation of a coating to a cathodically-protected pipeline or structure without first testing its resistance to cathodic disbondment can result in catastrophic failure of the coating. However, there are over twenty international standard test methods to evaluate a coating’s inherent resistance to cathodic disbondment; each with its own set of parameters and materials, which can …

High-Temperature Service (Heat-Resistant) Coatings: Industries, Coating Types, Testing Protocols and Consequences of Testing Inconsistencies

High temperature-resistant coatings are used in a variety of industries and markets to prevent corrosion of steel subjected to extreme temperatures while in service. There are several testing protocols that are used to evaluate the performance of these coatings; however, performance comparisons are challenging since there is little uniformity or consistency of the test methods. …

Interior Pipe Coatings for Transporting Potable Water – Types and Considerations

Introduction Throughout most the world in developed countries, the public relies on access to a safe drinking water supply; something we frequently take for granted until it is compromised. Potable water frequently traverses through steel pipe to deliver it both safely and economically. However, because water in contact with steel will cause it to corrode, …

Under Pressure: The Effects of Rapid Depressurization on Coating System Performance

The oil and gas production and distribution industry presents unique challenges associated with protective coatings performance. Recently, a group of environmental activists, armed only with bolt cutters, broke into valve stations across four states and closed the shut-off valves of five cross-border oil pipelines, which can transport as much as 2.8 million barrels of crude …
