Interior Pipe Coatings for Transporting Potable Water – Types and Considerations

3 Comments / Coating Standards, Coatings, Pipeline Coatings, Tanks, Water/Wastewater / By KTA Staff

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, […]

The Missing Piece: Collaborations Between Field Investigators and Laboratory Chemists

1 Comment / Coating Failure, Coatings, Lab Testing / By KTA Staff

Chances are, you have seen at least one procedural cop drama over the years. These shows all tend to follow a fairly standard formula: the crime occurs, the investigator is called in, the investigator gathers clues and interviews suspects, evidence is sent to a laboratory to confirm or refute theories, and by the end of

Coating Adhesion Testing using Knife/Tape Methods

5 Comments / Coating Standards, Inspection, Instruments / By KTA Staff

Introduction Adhesion is an important physical characteristic of applied coating films and systems, and testing is frequently used as an indicator to whether an adequate bond exists between the substrate and primer (first coat) and/or between coats in multiple coat applications. Adhesion testing may be a requirement of a coating specification, or may be used

Use of Overhead Cranes, Powered Industrial Trucks, and Slings – Risks of Unsafe Use and OSHA/ANSI Requirements for Training and Operation

Health & Safety / By KTA Staff

Introduction Efficient handling of materials is vital to the steel fabricating and coating shop processes. These facilities typically employ powered industrial trucks, overhead and gantry cranes, and slings to move tons of materials such as steel within the confines of a building, between buildings, and to/ from transportation vehicles. Material handling is not done without

Surface Profile Measurement Options on Rough/Pitted Steel Surfaces

Bridges, Inspection, Instruments, Steel, Surface Profile / By KTA Staff

Introduction Surface profile is defined as a measurement of the maximum peak-to-valley depth generated by abrasive blast cleaning and impact-type power tools. These operations effectively increase the surface area and provide an “anchor” for the applied coating system. The surface profile depth must be compatible with the total coating system thickness; typically, the thicker the

OSHA’s Final Rule on Beryllium: Key Provisions and Proposed Modifications Affecting the Abrasive Blast Cleaning Industry

Health & Safety / By KTA Staff

Introduction The International Agency for Research on Cancer (IARC) classifies beryllium and beryllium compounds as carcinogenic to humans, and the Environmental Protection Agency (EPA) classifies inhaled beryllium as a possible carcinogen. Despite its toxicity, beryllium is an important material in the aerospace, electronics, energy, telecommunication, energy, medical and defense industries due to its physical properties,

Coating System Selection and Determining “Or Equal”

2 Comments / Coatings, Specifications, Uncategorized / By KTA Staff

The Construction Specifications Institute (CSI) provides a format for preparing specifications that is often adopted for use in the coatings industry. It contains three primary sections, including General, Products and Execution. The Products section typically contains the specified coating system. There are several ways that a coating system can be specified, one of which is
