Many facility owners, particularly public agencies, have a standard specification for lead paint removal projects that has stood the test of time, and that likely went through a rigorous review process to get to the final version of the published document. Whether it’s for a bridge or a water tank, the owner has likely used

This podcast covers measuring surface profile and discusses two fundamentally different methods for measuring profile. Panelists discuss some of the complications that may occur when using both methods on the same job. The video (YouTube) version of the podcast features a variety of hands on demonstration and instrumentation use. KTA Chief Operating Officer, Bill Corbett, addresses

Abrasive blast cleaning is the process by which an abrasive media is propelled through hoses and a blast nozzle by means of compressed air. The abrasive exits the nozzle at a high rate of speed (velocities approaching 650 – 1,700 feet per second) and as it impacts the surface removes existing materials and imparts a roughness (surface profile). The abrasive used

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

When a coating system fails prematurely, it is rarely because of the coating itself. Either the surface preparation was inadequate, the surface was contaminated, or the coating was mixed or applied incorrectly. As the old adage goes, a house is only as strong as the foundation it is built on. When it comes to coatings,

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
Background Ergonomics is a field study that involves the application of knowledge about physical, psychological, and biomechanical abilities and limitations of the human body. This knowledge is applied to the planning, design, and evaluation of work environments, jobs, tools, and equipment to improve worker performance, safety and health. In layperson terms, ergonomics is fitting the

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.
