The ASC ENGINEERED SOLUTIONS 830540704 is a black steel extra heavy (XH) pipe nipple sized at 2-1/2 inches by 3-1/2 inches. This close-pattern threaded fitting connects two female-threaded pipe fittings or valves and is used to extend or transition pipe runs in gas, steam, and industrial fluid systems. The extra heavy wall thickness provides greater pressure capacity and durability compared to standard-weight nipples. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this fitting type.
This nipple is suited for commercial and industrial piping applications where a short, rigid connection between fittings is required. Common uses include gas distribution headers, steam supply and return lines, compressed air systems, and industrial process piping. The 2-1/2-inch nominal size places it in the range of larger-diameter pipe systems typically found in commercial mechanical rooms and industrial facilities rather than residential service.
Designed as an OEM-style replacement or new-installation fitting for 2-1/2-inch nominal black steel threaded pipe systems in gas, steam, and industrial fluid applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fittings. Apply an appropriate thread sealant or pipe tape rated for the intended service medium. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
