1-1/4" MNPT x 4 ft Black Pipe Sch 40

This 1-1/4 inch nominal pipe size welded steel pipe comes threaded both ends with male NPT threads and a black finish. It is made from Grade B steel and globally sourced. The pipe is rated for a maximum operating pressure of 1145 psi at 72 degrees F and handles air, natural gas, non-potable water, oil, and steam up to 600 degrees F.

Suitable Applications and Limits

Builders needing a 4-foot length of Schedule 40 black steel pipe with MNPT ends for standard pressure piping will find this part fits. It is not for potable water lines. Buyers requiring gravity-flow drainage, different end connections, longer or shorter lengths, or higher temperature ratings above 650 degrees F for steam should look at other options.

1145 psi Pressure Rating at 72 Degrees F

The decisive specification is the maximum operating pressure of 1145 psi measured at 72 degrees F. This single figure determines whether the pipe meets the design pressure of your air, gas, oil, or steam system. Verify your system pressure against this rating before purchasing.

Questions about this item

What size Class 150 fitting does the 1-1/4 in. nominal pipe need to connect?

The pipe has 1-1/4 in. MNPT threads on each end, so a matching 1-1/4 in. Class 150 female fitting is required.

Can the welded Grade B steel pipe handle the same 1145 psi rating at 600 Degrees F steam service?

Yes, the maximum steam pressure is rated at 1145 psi at 650 Degrees F, covering 600 Degrees F operation.

How do I confirm the pipe is holding its 1145 psi rating after installation?

Pressurise the system to the design pressure and inspect every joint for leaks; no pressure drop indicates the Sch 40 wall is performing.
