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
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
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
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
Abrasive blast cleaning is the process by which an abrasive media is propelled through hoses and a blast nozzle by means of compressed air. The abrasive exits the nozzle at a
An international airport was in the midst of an expansion project. As part of the project, 24-inch-diameter jet fuel piping was being installed by a
Introduction When applying coating system to structures such as bridges, tanks, and pipelines the main goal is to apply a continuous film to help prevent
When a coating system fails prematurely, it is rarely because of the coating itself. Either the surface preparation was inadequate, the surface was contaminated, or
KTA Professional Engineers and Senior Consultants Jay Helsel & Mike Reina discuss maintenance painting including when to touch-up, overcoat, or remove & replace the coating.
Installation of a coating to a cathodically-protected pipeline or structure without first testing its resistance to cathodic disbondment can result in catastrophic failure of the
