The ASC Engineered Solutions 830536520 is a black steel extra heavy (XH) pipe nipple sized at 2 inches x 4 inches. Pipe nipples are short threaded pipe sections used to connect fittings, valves, and other piping components in a run. The extra heavy wall construction provides greater strength and pressure tolerance compared to standard weight nipples. This nipple is manufactured from black steel, making it well-suited for gas, steam, and industrial piping systems where corrosion resistance from galvanizing is not required. Licensed plumbers, pipefitters, and mechanical contractors typically install this type of hardware.
This black steel XH nipple is intended for use in commercial and industrial piping applications, including natural gas distribution, steam lines, air systems, and hydronic heating systems. The 2-inch diameter makes it a common fitting in medium-capacity piping runs. Its extra heavy wall thickness suits applications where standard wall pipe would not meet pressure or mechanical load requirements. Always verify local code requirements for material acceptability before installation.
Designed as an OEM-style replacement or direct-install black steel XH nipple for standard 2-inch threaded pipe systems in commercial and industrial piping assemblies.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local and national codes, including IFGC and ASME B31 standards where applicable. Shut off all gas, steam, or fluid supply and depressurize the line before removing or installing any pipe nipple. Use appropriate pipe thread sealant or PTFE tape rated for the service medium. Do not over-tighten threaded connections, as this can damage threads or fittings.
