  • Schedule 80 wall rated for 2000 psi at 150 °F
  • Non-threaded ends allow custom welding or threading on site
  • Continuous weld construction meets ASTM A53 Type F Grade A
  • Black steel finish resists corrosion in water and steam lines
  • 3-foot length provides ready-to-cut stock for 1-inch nominal pipe

Black Steel Pipe Nipple Schedule 80

This 1-inch nominal black steel pipe nipple measures 3 feet in overall length and is built to Schedule 80 wall thickness for high-pressure plumbing and industrial piping systems. The continuous weld construction and non-threaded ends allow custom threading or welding during installation. It conforms to ASTM A53 Type F Grade A standards for consistent material quality.

Pressure Capacity and Operating Headroom

The nipple handles a maximum working pressure of 2000 psi at 150 degrees Fahrenheit and a maximum steam pressure of 300 psi WSP, providing substantial headroom for demanding hydraulic and steam lines. The 11/64-inch wall thickness supports these ratings while maintaining an inside diameter of 1 3/64 inches for flow capacity. Systems exceeding these pressure or temperature limits will require a higher-rated fitting.

Schedule 80 Interface Practical Limits

The Schedule 80 designation defines the wall thickness and pressure envelope; the non-threaded connection type means the installer must add threads or weld joints to match the surrounding piping. The 1 5/16-inch outside diameter determines compatibility with standard 1-inch nominal pipe clamps, valves and fittings. California Proposition 65 warnings apply due to chemical content in the black steel material.

Questions about this item

Will the 1 in nominal size and 1 5/16 in outside diameter match my existing Schedule 80 fittings?

Yes, the nipple follows ASTM A53 Type F Grade A dimensions for Schedule 80, so the 1 5/16 in outside diameter and 11/64 in wall thickness align with standard Schedule 80 sockets and weld-neck flanges.

How can I confirm the continuous weld is sound after installation?

Perform a visual inspection of the full-length continuous weld, then pressure-test the assembled line up to 2000 psi at 150 °F or 300 psi steam; no leakage indicates the weld and base metal are performing to spec.

Does the 3 ft non-threaded nipple ship with any gaskets, bolts or thread-sealant?

The box contains only the black steel nipple itself; gaskets, bolts, welding consumables or thread-sealant for flanged or threaded connections must be purchased separately.
