The ASC Engineered Solutions 830041000 is a black steel pipe nipple sized at 2 inches by 12 inches, designed for use in threaded pipe assemblies across a wide range of mechanical systems. This close-tolerance fitting connects threaded pipe runs and serves as a standard extension or offset piece in gas, steam, and non-potable water piping systems. Weighing 3.5 pounds, it is built from black steel, which provides the wall strength required for higher-pressure and higher-temperature service lines. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of fitting.
This nipple is suited for use in residential and light commercial mechanical rooms, boiler rooms, and utility installations where black steel pipe is the standard material of choice. Common applications include natural gas distribution piping, steam heating systems, and industrial process lines. The 2-inch diameter accommodates moderate to high flow capacity in main distribution runs, making it a practical choice for branch headers and riser connections in larger systems.
Designed as a standard NPT-threaded black steel nipple for use in gas, steam, and non-potable water piping systems requiring 2-inch threaded connections.
Installation of black steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the system type. Shut off and depressurize the system fully before removing or installing any threaded fitting. Use an appropriate thread sealant rated for the intended service, whether gas, steam, or water, and inspect threads for damage before assembly. Do not overtighten, as black steel threads can crack or strip under excessive force.
