Pipe and Pipe Fittings

Pipe and fittings weld together for a permanent connection that is stronger and less likely to leak than threaded and clamp-on connections.

Iron and Steel Clamp-On
Pipe and Pipe Fittings

Pipe and fittings connect with a clamp, so they can be taken apart as needed for maintenance and repair.

Iron and Steel Pipe
Fittings with Flanged Ends

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket to create an access point in a pipe line.

Other Steel Pipe Fittings
