The ASC ENGINEERED SOLUTIONS 4354002890 is a black steel seamless extra heavy (XH) pipe nipple sized at 1-1/2 inches by 6 inches. Manufactured to ASTM A106 Grade B standards, this nipple is designed for use in high-pressure and high-temperature piping systems where wall thickness and material integrity are critical. The seamless construction eliminates weld seams, reducing the risk of failure under stress. Licensed plumbers and pipefitters typically install this fitting in industrial, commercial, and mechanical piping applications requiring extra heavy schedule pipe connections.
This nipple is suited for steam, compressed air, water, and gas distribution systems where standard-weight fittings are not adequate. The extra heavy wall thickness makes it appropriate for commercial and industrial installations operating at elevated pressures. It is a close nipple substitute in configurations requiring 6-inch pipe length between fittings or when transitioning between threaded components in black steel piping assemblies.
Designed as an OEM-style replacement or standard component for black steel threaded piping systems requiring 1-1/2 inch extra heavy schedule nipples in commercial and industrial plumbing and mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the system completely before removing or installing any threaded pipe component. Apply appropriate thread sealant or PTFE tape rated for the service medium before threading the nipple into fittings. Do not over-tighten threaded connections, as this can damage threads on mating fittings.
