Introduction Ironically, the demand for improved water quality has made the service environment of wastewater treatment facilities even more aggressive, requiring higher performance coatings for corrosion protection. Environmental...
Introduction Each year Liberty Mutual Safety Index ranks the top 10 causes of the most serious, nonfatal workplace injuries by their direct cost. The top ten leading causes in the 2017 index account for $49.9 billion, or 83.4% of...
Unlike many industrial structures, ships often contain a variety of multi-layer coating systems on a single vessel, and even on the exterior hull itself, often including a complex sequence of anticorrosive layers followed by antif...
While water is life-sustaining to humans, it is detrimental to buildings; especially ones made from single-wythe concrete masonry walls. It causes paint to fail, cracks to form in mortar joints, and blocks to spall. These defici...
The following is a guideline for witnessing and verifying qualification testing of Welding Procedure Specifications (WPS) according to the AASHTO/AWS D1.5-2015 Bridge Welding Code. The guidelines identify what the third-party insp...
When a large-scale bridge is in need of significant reconstruction, many factors should be considered prior to initiation of the project. Part of this particular reconstruction involved repainting of the structural steel on a 40-f...
Coatings technology for lining of tanks, piping, and vessels has rapidly advanced in recent years. Extremely tightly-crosslinked coatings are relatively impermeable, and specialty resins and pigments are formulated into linings sp...
Weathering steel, often referred to by the genericized trademark COR-TEN steel, is a group of steel alloys developed to form a stable corrosion-resistant surface after several years exposure to weather, potentially eliminating the...
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 ...
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 (...
