Anvil 1/2" x 6 ft Black Steel Pipe Nipple Sch 80 Non-Threaded

Anvil 1/2 in Black Steel Pipe Nipple

This 6 ft Schedule 80 nipple is made from welded black steel with a continuous weld seam. It has a non-threaded connection type, so it is intended for field welding or grooved coupling installation. The pipe suits plumbing, hydraulic and low-pressure steam systems that require a heavy-wall conduit. Buyers who need threaded ends or a shorter factory-cut length cannot use this item as supplied.

Build Quality and Connection Implications

The pipe meets ASTM A53 Type F Grade A with a 9/64 in wall thickness, an inside diameter of 39/64 in and an outside diameter of 53/64 in. The non-threaded ends mean installers must weld or groove the pipe on site, which demands appropriate equipment and qualified personnel. The black steel finish provides no corrosion protection, so external coating or galvanising is required for exposed or damp environments. Systems that require immediate thread engagement or a flanged joint will need additional fabrication steps.

Pressure and Temperature Limits

The nipple is rated for a maximum pressure of 2000 psi at 150 degrees F and a maximum steam pressure of 300 psi WSP. These limits define the safe operating envelope for water, oil, air and saturated steam service. Exceeding either pressure or temperature rating risks joint failure or pipe rupture. Installations that operate above 150 degrees F or require higher steam pressure must select a different schedule or material.
