Professional Applications & Engineering Value

This heavy-duty Schedule 80 steel pipe nipple delivers critical engineering solutions for industrial fluid systems requiring high-pressure containment and corrosion resistance. The black-coated steel construction provides essential protection against environmental degradation while maintaining NPT threading precision for leak-free connections in compressed air, natural gas distribution, petroleum transfer, steam lines, and water systems. Its seamless design eliminates weak points common in welded alternatives, while the thick-wall Schedule 80 profile (0.191" wall thickness) ensures structural integrity under cyclic pressure loads. Engineered for 300/600 flange class compatibility, this nipple serves as a reliable connector in pump stations, processing equipment, and industrial piping networks where failure prevention is paramount.

Specification Summary & Compliance

Manufactured to exacting ASME B1.20.1 specifications for NPT thread form and dimensional accuracy, this pipe nipple meets ASTM A106/A53/A733 material standards for seamless steel construction. The product maintains precise dimensional tolerances with 1.278" ID and 1 21/32" OD for consistent fitment. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety, while the Schedule 80 wall thickness provides engineered pressure containment for industrial applications.
