The MUELLER INDUSTRIES 585-300 is a 1-inch nominal, Schedule 40 black steel pipe nipple threaded on both ends with NPT male threads. Constructed from Grade B welded steel using the electric resistance weld process, it measures 30 inches in overall length with a 1 5/16-inch outside diameter and a wall thickness of 1/8 inch. This pipe is rated for a maximum operating pressure of 150 psi and a maximum steam pressure of 1315 psi at 650 degrees F, with an operating temperature range of -20 degrees F to 600 degrees F. Plumbers, pipefitters, and HVAC technicians install this pipe in a wide range of fluid and gas distribution systems.
The 585-300 is suited for residential and commercial applications involving air, natural gas, non-potable water, oil, and steam distribution. Its black steel finish and Class 150 fitting compatibility make it a standard choice for gas supply lines, steam systems, and industrial piping runs where galvanized or stainless pipe is not required. The threaded-on-both-ends configuration allows direct connection to Class 150 fittings, valves, and couplings without additional field threading.
Compatible with Class 150 threaded fittings, couplings, valves, and unions using standard NPT connections. Designed as an OEM-style replacement or new-installation pipe for Schedule 40 black steel piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off the gas or fluid supply and depressurize the line before making or breaking any threaded connection. Apply an appropriate thread sealant or PTFE tape rated for the service medium before assembly. Do not use this pipe for potable water service.
