Characterizing the Service Environment when Selecting Coatings

Coatings, Specifications / By

One of the tasks for a specifier when selecting coating systems is to properly and thoroughly identify the prevailing service environment for existing structures/facilities, or the anticipated service environment for new structures or facilities.  Stated more simply, once the coating system is installed, what will it be subjected to, under both normal and upset operating […]

The Importance of Preparing Jobsite Standards for Surface Cleanliness and Surface Profile Depth Prior to Production Operations

2 Comments / Inspection, Specifications, Surface Preparation, Surface Profile / By

Introduction Surface preparation prior to coating installation is generally composed of two goals: achieving the minimum specified surface cleanliness, and achieving the specified range of surface profile (surface roughness). While these goals may be achieved in a single operation (e.g., by abrasive blast cleaning) or two separate operations (e.g., by water jetting or chemical stripping,

Frequency of Measurements in the Coatings Industry

2 Comments / Coating Application, Coatings / By

The Issue There are two questions that can arise when performing in-process quality checks of surface preparation and coating application processes, or when evaluating the performance of a coating system already in service. These include, “How do I perform the tests,” and “What is the frequency required to ensure my test data is representative?” The

Measuring Peak Density Using Optical Grade Replica Tape  

Inspection, Instruments, Surface Profile / By

Introduction Most industrial and marine protective coatings rely on a mechanical bond to the substrate to remain attached while in service. This bond is generally provided by a surface profile or anchor pattern that is imparted into the surface prior to application of the coating system and effectively increases the surface area of the substrate

Understanding Slip Coefficient and Tension Creep Testing of Coatings Used in Slip-Critical Bolted Connections

2 Comments / Bridges, Coating Standards, Coatings, Lab Testing / By

Bridges, buildings, and other structures commonly include designed bolted connections of steel beams, girders, and other structural members using connection/splice plates of various sizes and configurations. High-strength bolts are used to secure the connections. The holes in the steel members and the connection/splice plates are larger (typically 1/16–1/8 of an inch larger) than the bolt
