Evaluation and Repair of a Liquid Sulfur Holding Tank

This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.

Corrosion Basics: Coating New Construction Seagoing Vessels

Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.

Innovative Polymeric Solution for Flanged Pipework Protection

Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.

New Mexico’s Iconic Steel Bridge Turns 50

In September 2015, when the iconic Rio Grande Gorge Bridge reached its 50th year of service, it coincided with the bridge’s biennial inspection that scrutinizes the entire structure for coating failure, corrosion, cracks in the steel, and other structural integrity issues.

High-Performance Spray-Applied Waterproofing Protects Concrete and Steel

Coating failure has led to significant degradation of America’s structural elements. As an alternative to more traditional materials, new high-performance, spray-applied waterproofing alternatives are being used to protect and maintain critical infrastructure

New Standards Provide Maintenance Guidelines for the Electric Power Industry

NACE International and the Institute of Electrical and Electronics Engineers (IEEE) have joined together to provide joint industry standards that address above-grade and below-grade corrosion of steel transmission and distribution structures.

Composite Repair Material Bonds to Poor Substrate on Historic Vessel

This former combat vessel suffered from numerous leaks and a pitted surface. It needed a long-term coating repair solution capable of bonding to a poor substrate with rapid curing times.

Guide Helps Estimate Cost and Service Life for Protective Coatings

The practical guide was designed to help coatings engineers or specifiers determine candidate protective coating systems for particular industrial environments.

Trailer Study: Wax Coating Shows Promise in Resisting Corrosion

Salt spray exposure tests revealed the strength of wax-based coatings in withstanding exposure to sodium chloride (NaCL) as a corrosive agent in truck and trailer manufacturing operations.

Protecting a Pipeline When Its Coating Has Aged

The country’s existing pipeline infrastructure was built with materials that are no longer used today, although they were state-of-the-art at the time. Coating materials, for example, have significantly improved over those used decades ago.

The Science Behind Field-Applied Liquid Epoxy Pipeline Coatings

Field-applied liquid epoxy coatings have moved from the shadows to become one of the most important methods of pipeline corrosion protection. This article presents the science behind this essential process for protecting underground pipelines from corrosion.

Assessing the Risk of Coating Failure from Residual Soluble Salts

Residual soluble salts are contaminants on a substrate surface that affect coating performance. The primary soluble salts that the coatings industry must manage are in the form of chlorides, sulfates, and nitrates.

Installation Complete on First U.K. Long-Length Coated Rail Project

Zinc-rich coated rail, which protects in the most corrosive of environments, is being supplied in longer lengths and is seen as ideal for track environments, such as those in tunnels.

Drone Shows Promise in Measuring Coating Thickness

The drone utilizes specialized software, sensors, and an electronic coating thickness gauge system to collect and record nondestructive dry film thickness millage thickness measurements.

Specification and Inspection Play Vital Role in Coating Steel Structures

This article provides basic concepts for young corrosion engineers to improve skills on coating specification and inspection that will impact structural steel painting work.
