The ASC ENGINEERED SOLUTIONS 4354001640 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/4 inch by 3 inches. Manufactured from A106B-grade seamless black steel, this nipple is built to handle the elevated pressure and temperature demands typical of commercial and industrial piping systems. At 0.33 pounds, it is a compact fitting intended for threaded pipe assemblies where standard-wall fittings are insufficient. Licensed plumbers and pipefitters install this type of nipple as a short connecting piece between threaded fittings, valves, or equipment ports in gas, steam, and fluid distribution lines.
This nipple is suited for use in commercial and industrial piping installations where extra heavy wall thickness is required by system design or code. Common applications include natural gas distribution, steam lines, compressed air headers, and hydraulic or fluid transfer systems. The seamless construction eliminates weld seams, making it appropriate for higher-pressure service runs. It is classified as an import fitting per supplier data.
Designed as an OEM-style threaded pipe nipple for use in extra heavy black steel pipe systems requiring 3/4 inch NPT threaded connections.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and fuel gas codes such as the IFGC or ASME B31 piping standards. Shut off and depressurize the system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium prior to assembly. Do not over-tighten threaded connections, as this can damage threads on mating fittings or valves.
