Professional Applications & Engineering Value

This heavy-duty Schedule 160 threaded pipe nipple delivers engineering excellence for demanding industrial fluid systems. The seamless black-coated steel construction prevents corrosion while the extra-thick 0.437" wall thickness withstands high-pressure applications including hydraulic systems, steam lines, and natural gas distribution. Precision NPT threads on both ends ensure secure connections that resist vibration and thermal cycling, making it ideal for Class 3000 steel fittings and 1500 flanges in chemical plants, oil refineries, and power generation facilities. The 3" diameter with 8" length provides optimal flow capacity while maintaining structural integrity under extreme operating conditions.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 thread standards with materials conforming to ASTM A106, A53, and A733 specifications. Features NPT threading with Class 2A tolerance for precise engagement. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives. Dimensions include 3" pipe size (Dash 48), 8" length, 2.626" ID, and 3-1/2" OD with Schedule 160 wall thickness.
