What Does Girth Weld Coating Mean?
A girth weld coating is a protective fluid layer that is applied to the metal surface of two pipes that have been joined along their circumference during pipeline construction. These coatings are designed to prevent corrosion and are often produced in the form of an epoxy or polyurethane.
Corrosionpedia Explains Girth Weld Coating
Welded components such as girth welds are susceptible to unique types of corrosion such as intergranular corrosion and crevice corrosion. Therefore, corresponding unique forms of corrosion prevention measures are performed to protect these welds. Such measures include the use of girth weld coatings, which are thicker than most coatings and are designed to withstand high temperatures.
