Black steel pipe nipple with threaded ends

Value Brand

Value Brand 1/2" MNPT x MNPT Black Steel Pipe Nipple Schedule 80

SKU CH-2QQG-DXDSS

A Schedule 80 black steel pipe nipple with MNPT threads on both ends, rated for 2000 psi at 150 °F and 300 psi steam at 550 °F

  • 1/2 in MNPT threads connect directly to matching fittings
  • Schedule 80 wall withstands 2000 psi at 150 Degrees F
  • Seamless black steel meets ASTM A106 and ASTM A733 standards
  • 6 in overall length suits tight plumbing runs
  • Rated for 300 psi steam service at 550 Degrees F

Threaded Black Steel Nipple

This Schedule 80 pipe nipple connects two female NPT fittings in hydraulic or steam systems. It is manufactured from seamless black steel to ANSI/ASME B1.20.1 and ASTM A106 standards. The 1/2 inch nominal size suits compact plumbing layouts in industrial or commercial settings.

Seamless Construction Benefits

The seamless wall eliminates a welded seam that could leak under cyclic pressure. A 9/64 inch wall thickness supports a 2000 psi rating at 150 degrees F and 300 psi steam pressure at 550 degrees F. Threaded ends allow direct assembly without additional couplings or adapters.

High-Pressure Steam and Hydraulic Lines

Installers needing a short, rugged connector for saturated steam or oil circuits will find the pressure ratings adequate. Systems requiring larger flow capacity, copper or stainless alloys, or flanged connections should specify a different fitting.

Questions about this item

Will the Schedule 80 wall thickness of 9/64 in need replacement due to corrosion?

The 9/64 in wall thickness provides extra material for corrosion allowance. Black steel has no coating, so lifespan depends on water chemistry and whether the system uses oxygen-scavenging treatment.

What pressure limit applies first during continuous 150 °F operation?

The 2000 psi rating at 150 °F is the governing limit for water service. Steam duty is capped at 300 psi and 550 °F, which is a separate design condition.

Does the black steel nipple radiate noticeable heat on a 150 °F steam line?

At 150 °F the 53/64 in outside diameter becomes hot to the touch. Uninsulated pipe will radiate heat into the space and pose a burn risk; insulation is standard practice.
