Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid handling systems. The welded construction combined with NPT threading creates permanent, high-pressure resistant connections that prevent leakage in compressed air lines, steam transfer, and hydrocarbon applications. The Schedule 40 wall thickness (0.133") provides optimal strength-to-weight ratio while the 48-inch length enables flexible installation between iron and steel flanges in class 125 and 150 piping systems. The black coating significantly enhances corrosion resistance, extending service life in humid or chemically aggressive environments where natural gas, oil, steam, and water are transported. This heavy-duty pipe nipple eliminates premature failure points through strict adherence to ASME B1.20.1 and ASTM A53/A733 manufacturing standards.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 specifications for NPT thread form with Class 2A tolerance, ensuring precise mating with standard fittings. The 1" Schedule 40 pipe maintains dimensional accuracy per ASTM A53 (1.049" ID, 1-5/16" OD) with welded construction meeting ASTM A733 requirements. Fully compliant with REACH (EC 1907/2006) regarding SVHC substances and RoHS 3 (2015/863/EU) directives, confirming environmental responsibility in industrial supply chains.
