Professional Applications & Engineering Value

This heavy-duty Schedule 80 threaded pipe nipple delivers critical performance in industrial fluid systems where reliability is paramount. The seamless 304/304L stainless steel construction eliminates potential failure points while providing exceptional resistance to corrosion, scaling, and chemical degradation. Engineered with NPT threading to ASME B1.20.1 specifications, it ensures secure, leak-tight connections in high-pressure applications including hydraulic systems, steam lines, and process piping. The thick-wall design maintains structural integrity under extreme pressure fluctuations and mechanical stress, making it ideal for demanding environments where standard fittings would fail. This industrial pipe nipple serves as a robust connector in chemical processing, power generation, and oil & gas applications where material compatibility and pressure rating compliance are essential for operational safety.

Specification Summary & Compliance

This 1 1/4" Schedule 80 NPT threaded pipe nipple features precision NPT thread form manufactured to ASME B1.20.1 dimensional standards with Class 2A thread tolerances. The component meets ASTM A733 specification for welded and seamless carbon and austenitic stainless steel pipe nipples. Constructed from 304/304L stainless steel with seamless manufacturing, it demonstrates full compliance with RoHS 3 (2015/863/EU) environmental directives. The product maintains critical dimensions including 1.278" ID, 1 21/32" OD, and 0.191" wall thickness to ensure proper fitment and pressure rating compatibility with Class 3000 fittings and Class 300/600 flanges.
