The ANVIL INTERNATIONAL INC 8700141800 is a black steel pipe in a 1-inch nominal diameter by 36-inch cut length. Black steel pipe is standard carbon steel pipe with a dark mill-scale finish, commonly used in gas distribution, fire suppression, and general plumbing systems where corrosion from exterior moisture is not the primary concern. This cut-length format is ready for threading or welding on-site and is suited for installation by licensed plumbers, pipefitters, and HVAC mechanics working on low-pressure gas or water piping systems.
This pipe is a practical fit for residential and light commercial applications where a specific 36-inch run is needed without field cutting. Common uses include natural gas supply lines, propane piping, fire sprinkler mains, and hydronic heating distribution. The 1-inch nominal size handles moderate flow volumes and fits standard 1-inch NPT fittings, valves, and couplings.
Designed as a standard cut-length black steel pipe for use with 1-inch NPT fittings, threaded unions, and couplings in gas, fire suppression, and general mechanical piping systems.
Installation of black steel pipe on gas systems must be performed by a licensed plumber or pipefitter in accordance with the International Fuel Gas Code (IFGC) and applicable local codes. Shut off and lock out the gas supply before cutting into or connecting to any existing gas line. Use an appropriate pipe threader or welding equipment suited to the pipe wall thickness and schedule. Inspect all joints for leaks with approved leak-detection solution before returning the system to service.
