Weld Fittings

Flanges are used to connect pipes, fittings and other equipment together to form a piping system. Flanges provide strength and integrity to pipelines, and also serve as access routes for cleaning, inspection or modification of piping assemblies. Flanges are joined by bolting together two flanges with a gasket between them to provide a seal.

Small / Large Tongue and Groove also available

ASTM A350-LF2, A182-304(L), 316(L) and other alloys are available by special order
