Often times, protective coatings for equipment and packages come as an afterthought; therefore, a Coatings Specialist is not always included in early purchasing discussions. Lack of the Coating Specialist participation in the preliminary workflow does not necessarily equate directly to a “bad outcome”, however there are fundamental details which, if highlighted early, can make a significant difference in the procurement process resulting in cost savings and competitive bids.

The use of fall protection equipment is very common nowadays. Still, however, many users do not know the basics of fall protection or the why and how this equipment function. Safety in general depends a lot on the use of common sense and proper due diligence. Understanding the risk of falling will lead us to be safe. It is a fact that we are all exposed to Gravity at all times 24/7; and we, humans in general, take little or no protection and precaution against gravity. The reality is that falls are never expected.
The program focuses on aiding an engineer, contractor, or decision maker in selecting the most appropriate type of traffic bearing coating system for a given application for parking structures. The program reviews the various type of traffic bearing coating systems that are offered in today’s market, the pros and cons of each and how the parking structure construction type (precast, cast in place, etc.) may affect performance of these systems.
Translational Corrosion Science, the subject of the SSPC 2015 presentation by the Department of Defense Corrosion (DoD) Prevention and Control Program, is a science-based process to accelerate the development and application of high-quality solutions to difficult material degradation problems, and to do so more economically. DoD has launched the translational corrosion science program, assisted by the National Defense University and Potomac Institute for Policy Studies, to fully develop the process concept and to implement the approach.
Changing conditions in the Oil and Gas industry are yielding greater corrosion protection challenges to the owners and operators of refineries, terminals, pipelines, railcars etc. Internal lining schemes which have traditionally been used for the storage and transport of crude oil and refined fuels may no longer be appropriate. The aggressive nature of crude oil (higher temperatures and more sour nature), high purity refined products and the increased use of biofuels globally necessitate the demand for better linings and more certain test results.
This paper will explore several variables which affect the tungsten carbide coating material deposited by a high velocity thermal spray process (HVTS) on Oil & Gas components such as valve sealing components (gate, ball, seat) and on other equipment (pistons for example on BOP’s or Blow Out Preventers). The purpose of coating these components is to gain wear/abrasion resistance as well as to impart some corrosion resistance.
In 2003 Connecticut Department of Transportation (DOT) conducted a study to quantify the throughput and cost savings potential of a PAS two-coat system versus a three-coat system. The study showed that a PAS two-coat system had a 31% increase in productivity and direct cost savings of approximately $6 per square foot, with indirect cost savings of $18 per square foot when including the benefits of reduced traffic congestion.17 PAS two-coat systems utilize a zinc-rich primer for galvanic protection; the epoxy and polyurethane layers are replaced by a high-build PAS topcoat.
Solventborne alkyd resins are widely used in industrial coatings because of their excellent gloss, good adhesion and wetting properties as well as excellent compatibility with other resin types. In many regions, however, the consumption of alkyds is diminishing as stringent environmental regulations drive the coatings industry towards lower volatile organic compound (VOC) systems. Waterborne (WB) coating systems have replaced some solventborne (SB) alkyd paints; however, these WB coatings typically do not offer the same performance as their solventborne counterparts.
Corrosion is a major concern for all materials during their service lives. In particular, salts such as sodium chloride (NaCl) are known to promote corrosion and detrimentally affect coating performance. Understanding how NaCl affects water uptake into a film and its interactions with corrosion-inhibiting pigments is important for developing the next generation of anticorrosive coatings.
A unique project was completed in Mid-2014 at the Powerhouse #3, Turbine Unit #23 refurbishment, Grand Coulee Dam, located in Washington State. The project scope includes a complete overhaul of the turbine bearings, windings, and critical components. As part of the overall scope, the contractor was charged with the task of coating the entire draft tube surface with an epoxy gel. The Bureau of Reclamation, based in Denver, Colorado, had conducted a site survey which indicated severe wear lines, which result in cavitation and the accompanying backpressure on the exiting water outflow to the Columbia River.
This paper discusses the revision of SSPC-PA 9, “Measurement of Dry Coating Thickness Using Ultrasonic Gages.” This standard describes procedures to measure the thickness of dry, homogeneous coatings applied to concrete, wood, wallboard, plastic, fiber and composite material using commercially available ultrasonic coating thickness gages.
Often when a polymeric flooring system fails, the cause of the problem is unknown. Forensic testing is used to determine the cause of failure while eliminating other potential causes. A basic understanding of the approach to a forensic investigation and the types of testing used will help aid in correcting the problem so future failures and project costs are reduced.
