The ASC Engineered Solutions 4354001700 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/4 inch by 6 inches. Manufactured to ASTM A106 Grade B specifications, this nipple is designed for use in high-pressure and high-temperature piping systems where wall thickness beyond standard Schedule 40 is required. The seamless construction eliminates a weld seam, improving pressure integrity under demanding service conditions. Licensed plumbers, pipefitters, and mechanical contractors typically specify this type of nipple in steam, natural gas, compressed air, and industrial fluid distribution systems.
This extra heavy nipple is suited for both commercial and industrial piping applications where code or system design calls for reinforced wall thickness. Common installation scenarios include boiler room piping, process gas lines, and mechanical room distribution headers. The 3/4 inch by 6 inch dimension makes it a practical close-nipple extender between fittings or valves in tight runs.
Designed as a standard threaded black steel XH nipple compatible with 3/4 inch Class 150 and extra heavy black iron threaded fittings and couplings used in commercial and industrial piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the International Mechanical Code (IMC) or International Fuel Gas Code (IFGC). Shut off and depressurize the system completely before removing or installing any threaded nipple. Apply an appropriate pipe thread sealant or PTFE tape rated for the service medium before threading the nipple into fittings. Do not over-thread or use tools that could deform the seating surfaces of the pipe ends.
