About Stainless Steel Pipe Flanges

Use stainless steel pipe flanges in pipe systems where you need to assemble or take apart pipe sections frequently for maintenance or testing. Unlike standard threaded fittings, flanges have exposed connecting bolts for better access. These flanges are made of corrosion-resistant stainless steel, which can withstand harsh conditions such as exposure to saltwater and some chemicals. Stainless steel can also protect the material in the pipe system from environmental contaminants, even if scratched.

Permanently install these socket-weld flanges by inserting an unthreaded pipe end into the flange and fillet welding the flange and pipe together. Socket-weld flanges have a ridge that stops the pipe end from going all the way through the flange, so your pipe hits the right spot without having to measure.
