The ASC Engineered Solutions 4354002090 is a black steel seamless extra heavy (XH) pipe nipple manufactured to ASTM A106B standards. Measuring 1 inch in diameter by 6 inches in length, this nipple is constructed from black steel for use in high-pressure and high-temperature piping applications. The seamless construction eliminates weld seams, delivering consistent wall thickness and superior pressure integrity throughout the fitting. Weighing approximately 1.01 pounds, it is suited for demanding industrial and commercial installations where standard-weight fittings are not sufficient.
This A106B seamless extra heavy nipple is appropriate for steam, gas, oil, and water piping systems in commercial and industrial settings. Its extra heavy wall rating makes it a common choice in mechanical rooms, boiler rooms, and process piping installations where elevated pressure ratings are required. Licensed plumbers, pipefitters, and mechanical contractors typically specify XH nipples in systems subject to high thermal cycling or elevated service pressures.
Designed as an OEM-style replacement or new-installation fitting for 1-inch black steel piping systems requiring extra heavy wall seamless nipples per ASTM A106B specification.
Installation should be performed by a licensed plumber or certified pipefitter in accordance with applicable mechanical and plumbing codes. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Use appropriate pipe thread sealant or PTFE tape rated for the service fluid and temperature. Inspect threads on both the nipple and mating fitting before assembly to ensure proper engagement and avoid cross-threading.
