Ultra-Thick-Wall Iron and Steel Unthreaded Pipe Nipples and Pipe

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. It is for use in noncorrosive environments.

Pipe—Unthreaded

Male

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

High-Pressure Iron and Steel Socket-Connect Pipe Fittings

Socket-connect fittings 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 have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.

Extreme-Pressure Iron and Steel Socket-Connect 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.
