Fluid Handling

Pipe Flanges

Bolt together with a gasket to create an access point within a line

Pipe Straights

Join lengths of pipe to send contents in one direction

Pipe Stub Ends

Connect a pipe flange to a pipe without needing to weld it in place

Pipe Expansion Joints

Pipe Expansion Joints

Reduce stress, vibration, and noise in piping systems by absorbing movement

Pipe Bleed Rings

Pipe Bleed Rings

Access inside a pipe line to vent pressure, drain liquid, and take samples

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Orifice Valves

Restrict the flow of liquids and gases to precisely control rate and pressure

Sealing

Pipe Gaskets

Form tight seals when connecting flanged pipe fittings
