Investigating Failure: Considerations for Reconstruction of a Bridge Exhibiting Staining

When a large-scale bridge is in need of significant reconstruction, many factors should be considered prior to initiation of the project. Part of this particular reconstruction involved repainting of the structural steel on a 40-foot-wide lift bridge that had a total length (including approaches) of 2,877 feet, with a main span of 418 feet. The […]

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,

Premature Corrosion of Porcelain Enamel-Coated Panels

Background of Design Specifications – Five stations of a commuter rail transportation system were exhibiting corrosion and coating adhesion problems.  The train stations were constructed approximately six years prior to observed coating failure. The steel surfaces (column covers, wall and ceiling cladding, soffit, security screens and structural support systems) were to receive a porcelain enamel protective
