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.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

Extra-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 extra-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.
