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.
