What is Girth Flange / Body Flange?
A Girth Flange (also known as a Body Flange) is a circular, ring-shaped flange welded around the circumference (girth) of pressure vessels, shells, tanks, or large diameter piping. It is used to join two cylindrical sections—typically as a structural or maintenance access point in equipment that cannot be made in a single piece due to size, transport, or fabrication constraints.
Why choose A105 Girth Flange:
Overall, A105 girth flanges are a reliable and versatile choice for various industrial applications due to their strength, affordability, and corrosion resistance.
