The Atmospheric Plasma Coating Removal (APCR) process provides a unique new way to quickly and safely remove the toughest industrial coatings. As with any new process a thorough examination of the possible risks to the end users and the environment is critical. APS hired an environmental testing facility to conduct a series of experiments and provide an assessment of noise, dust, and select chemicals to determine the safety of the APCR process.
The durability of a coating can be described in a simplified manner as how well it adheres to the substrate and how well it performs over time once exposed to the environment. Oil and gas pipeline coatings need to withstand exposure to both mechanical and chemical forces for long periods of time to extend the life of the pipeline. A new class of 100% solids polyester polyols have been developed which can offer improved performance in urethane coating applications compared to other common protective systems such as epoxies, aspartics and solventborne polyesters
When it was time for a major fertilizer distribution facility in the Midwest to have its conveyor structure repainted, the owner started contemplating full-time independent third-party inspection. After reviewing the contractor’s schedule and the size of the crew, it became apparent that this approach would interfere with the contractor’s operations and be cost prohibitive for the owner.
This annual paper summarizes environmental, health and safety issues that may impact SSPC members. This paper discusses current and expected EPA and OSHA regulatory rulemaking, emphasis programs, enforcement initiatives or other similar topics. This paper will incl ude a discussion on enforcement and insights of the silica and hazardous waste standards. Most of the information is taken directly from the respective agency’s published regulatory agenda, supplemented by anecdotal information gathered from various prof and conferences. essional journals, seminars
Low-viscosity oils could potentially act as self-healing barrier coatings because they can readily flow and reconnect to heal minor damage. For the same reason, however, they typically do not form stable coatings on metal surfaces. Increasing viscosity helps to stabilize the oil coating, but it also slows down the healing process. Here, we report a strategy for creating highly stable oil coatings on metal surfaces without sacrificing their remarkable self-healing properties.
With the increasing global energy demand, the transportation volume of natural gas increases rapidly, and pipeline transportation has become the most commonly used transportation mode of natural gas. Hydrogen is produced as a byproduct of ethylene production from ethane. Hydrogen is flammable and explosive. If it is directly discharged into the atmosphere, there are some safety risks. As a kind of efficient and clean secondary energy, hydrogen can not only avoid energy waste, but also increase economic benefit if it is mixed into natural gas pipeline.
Plural-component coatings have historically presented numerous challenges for contractors, with significant material, time, and labor costs tied to mixing two or more components prior to application. After the components are mixed, logistics issues can also arise, with limited time available to apply the coating.
Cleaning, coating, and the nondestructive testing (NDT) of corrosion-susceptible surfaces requires extensive manual labor, often at vertical heights that create a dangerous occupational environment. Drones, also known as unmanned aerial systems (UAS), unmanned aerial vehicles (UAV), or small unmanned aerial vehicles (sUAV) can be leveraged to perform some of these tasks, including cleaning and coating, while keeping workers safely on the ground.
Surface cleanliness has been measured visually for the past 30 years using SSPC –VIS- 1 (ISO 8501-1) reference photographs. This method, while recognized as the industry standard, does have its disadvantages. It is deemed a subjective measurement rather than objective and is vulnerable to human error.
Modern design, manufacturing and field-testing specifications include surface profile and adhesion testing on the assumption that they are linked to long term corrosion prevention. There are a number of careful studies, dating back decades, that find no link between measurements of adhesion and (undercutting) corrosion performance, but other studies do, and the concept remains intuitively appealing and widely assumed.
To address questions and concerns in the protective and marine coatings market, new laboratory data has been generated regarding corrosion rates and mechanisms that will help eliminate some of the assumptions regarding the role of soluble salts. These assumptions include soluble salt types such as chloride, sulfate, and nitrate along with the resulting conjugate corrosion products.
