1-1/4" Schedule 40 Black Steel Pipe

This 3-foot threaded pipe is built from welded Grade B steel with a black finish for air, natural gas, non-potable water, oil and steam distribution. It suits installers and maintenance teams needing a standard Class 150 compatible length for permanent or temporary piping runs.

Sustained pressure and temperature limits

The pipe handles a maximum operating pressure of 1145 psi at 72 degrees Fahrenheit and a maximum steam pressure of 1145 psi at 650 degrees Fahrenheit. Continuous service is rated from -20 degrees Fahrenheit up to 600 degrees Fahrenheit without gravity flow dependency.

Threaded ends simplify assembly

Male NPT threads on both ends allow direct connection to Class 150 fittings without welding on site. The 1 3/8 inch inside diameter matches nominal 1-1/4 inch sizing, so installers must verify fitting compatibility and thread sealant requirements before pressurising the system.
