Value Brand 1" MNPT x 5 ft TBE Black Pipe Sch 40

SKU CH-1FWE-C1XWP

A 5-foot Schedule 40 black steel pipe with 1-inch MNPT threads on both ends, rated for 150 psi at 150 °F and meeting ASTM A-53 and ASTM A-733 standards

  • 1 in nominal size fits standard plumbing connections
  • Schedule 40 wall thickness rated for 150 psi at 150 °F
  • Electric resistance weld construction meets ASTM A-53 and A-733
  • Threaded both ends with MNPT for quick installation
  • Black steel pipe suitable for water, gas and steam up to 1315 psi WSP

Pipe purpose and fit

This Schedule 40 black steel pipe measures 1 inch nominal size and 5 feet overall length with male NPT threads on both ends. It suits plumbing, gas and compressed-air lines that require a welded, threaded steel nipple. Builders needing plastic, copper or larger-diameter pipe should choose a different product.

Pressure limits and heat

The pipe carries a maximum water pressure of 150 psi at 150 degrees F and a steam rating of 1315 psi WSP at 650 degrees F. Wall thickness is 1/8 inch, giving an inside diameter of 1 3/64 inch and an outside diameter of 1 5/16 inch. Systems operating above these pressures or temperatures need heavier-wall or alternative material.

Standards and compliance

Manufacturing follows ASTM A-53 and ASTM A-733 plus Federal Specification WWN 351, confirming electric-resistance-weld construction and dimensional tolerances. No coatings, sealants or fittings are included, so installers must supply thread compound and any required adapters separately.

Questions about this item

How do I install the 1" MNPT threaded ends and what step is often missed?

Apply thread sealant to the male NPT threads on both ends, then tighten into matching female fittings; the step often missed is using enough sealant to fill the tapered threads completely.

What maintenance or replacement will this Schedule 40 black steel pipe need over time?

Inspect for internal corrosion or mineral buildup periodically; replace the pipe if the 1/8 in wall thickness shows pitting or if leaks develop at the threaded joints.

What is the first pressure limit reached under sustained high-temperature steam use?

The 1315 psi steam rating at 650 °F is the governing limit for continuous steam service.
