How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Super-Thick-Wall Steel Threaded Pipe Nipples and Pipe

Also known as Schedule XXH, this heavy duty pipe has the thickest, strongest walls of all the threaded pipe we offer. Pipe is seamless, so it has a smooth interior for unrestricted flow. Use in noncorrosive environments.

Extreme-Pressure Socket-Connect Steel Unthreaded Pipe Fittings

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are for use in noncorrosive environments.

Union straight connectors separate into three pieces for access to your line.

Super-Thick-Wall Steel Unthreaded Pipe

For Use With: Air, Water, Oil, Natural Gas, Steam, Hydraulic Fluid
Specifications Met: ASTM A106, ASTM A733
Fittings: Use Class 6000 steel
Flanges: Use Class 1500 steel

With super-thick Schedule XXH walls, this pipe provides the strongest connections of all the unthreaded pipe we offer. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is for use in noncorrosive environments.

Extreme-Pressure Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges. Bolt two same-size flanges together with a gasket (sold separately) to create an access point in a pipe line. They are for noncorrosive environments.

Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.
