The ASC Engineered Solutions 830540746 is a black steel extra heavy (XH) pipe nipple sized at 2.5 inches by 4.5 inches. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and other piping components in a system. This nipple is manufactured from black steel, making it suitable for gas, oil, and industrial fluid piping applications. The extra heavy wall designation indicates increased wall thickness compared to standard-weight pipe, providing additional strength for higher-pressure or more demanding service conditions. Plumbers, pipefitters, and mechanical contractors install this type of fitting as part of threaded pipe assemblies in commercial and industrial systems.
This black steel XH nipple is used in threaded pipe systems across a range of applications including natural gas distribution, fuel oil lines, compressed air, and industrial fluid transport. The 2.5-inch nominal pipe size is common in larger commercial and light industrial installations. It is suited for interior mechanical rooms, boiler rooms, and similar environments where black steel pipe and fittings are the standard of construction.
Designed as an OEM-style replacement or standard component for threaded black steel pipe assemblies using 2.5-inch nominal pipe size fittings in commercial and industrial piping systems.
Installation of black steel pipe nipples is typically performed by licensed plumbers or pipefitters. Shut off and depressurize the pipe system completely before disassembly or connection. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before making threaded connections. Work must comply with applicable mechanical and plumbing codes, including IFGC requirements for gas piping applications.
