The ASC ENGINEERED SOLUTIONS 4309009312 is a nine-piece black steel nipple run set covering a fitting size range of 2 inches to 6 inches in extra heavy (XH) wall class. Nipple runs are pre-selected assortments of threaded pipe nipples used to make up close, short, and long threaded connections in piping systems. This set is suited for plumbing, steam, gas distribution, and industrial piping applications where extra heavy wall thickness is specified for added pressure capacity or mechanical durability. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of these components.
This nipple run is intended for systems that require black steel threaded pipe fittings from 2 inches through 6 inches. Extra heavy wall class nipples are commonly specified in commercial and industrial installations, including boiler rooms, mechanical rooms, and process piping where higher-pressure ratings or heavier-duty construction are required by code or engineering specification. The domestically sourced construction supports compliance with project specifications that require domestic-origin steel pipe products.
Designed as an OEM-style replacement and standard-fit component for black steel threaded piping systems requiring extra heavy wall nipples in the 2 inch to 6 inch size range.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including the International Plumbing Code (IPC) and International Fuel Gas Code (IFGC) where applicable. Always depressurize and isolate the piping system before removing or installing threaded nipples. Use appropriate pipe thread sealant or PTFE tape rated for the service fluid on all threaded connections. Inspect threads for damage before assembly to ensure a leak-free joint.
