The ASC ENGINEERED SOLUTIONS 4354002830 is a black steel seamless extra heavy (XH) pipe nipple sized at 1.5 inches by 3 inches. Manufactured to ASTM A106 Grade B standards, this nipple is designed for high-pressure and high-temperature piping applications where standard-weight fittings are not sufficient. The seamless construction eliminates weld seams, reducing potential failure points under stress. Plumbers and pipefitters install this type of nipple to connect sections of threaded pipe in gas, steam, and industrial fluid systems requiring extra wall thickness and mechanical strength.
This nipple is suited for commercial and industrial piping systems, including steam distribution, compressed air, and high-pressure gas lines. The extra heavy wall rating makes it appropriate for applications where elevated pressure ratings or added mechanical durability are required beyond what standard or schedule 40 fittings provide. It is also used in fire protection, HVAC hydronic systems, and general industrial plumbing where black steel pipe is the specified material.
Designed as an OEM-style replacement or standard component for threaded black steel pipe systems using 1.5-inch nominal pipe size fittings in extra heavy wall configurations.
Installation is performed by licensed plumbers or pipefitters working on threaded steel pipe systems. Shut off and depressurize the line completely before removing or installing any threaded nipple. Apply appropriate thread sealant or PTFE tape rated for the service fluid before threading the nipple into fittings. Follow applicable codes including the International Fuel Gas Code (IFGC) for gas service or the International Plumbing Code (IPC) for water and steam applications.
