Professional Applications & Engineering Value

This Schedule 40 stainless steel pipe nipple delivers exceptional engineering value through its 304/304L stainless steel composition, providing optimal resistance to corrosion and oxidation in aggressive media including steam, oil, and chemical processing systems. The welded construction combined with NPT threaded connections creates reliable, pressure-tight joints that eliminate leakage points in high-vibration industrial environments. Its dual-connection capability (threaded × butt weld) offers installation flexibility for maintenance and system modifications without requiring complete pipe replacement. Engineered for industrial pipe fittings in HVAC, petrochemical, and power generation applications, this component solves critical challenges in fluid containment while meeting stringent ASTM A312 and ASME B1.20.1 specifications for dimensional accuracy and performance reliability.

Specification Summary & Compliance

This 2 1/2" Schedule 40 pipe nipple maintains precise dimensional tolerances with NPT threading conforming to ASME B1.20.1 standards. Manufacturing compliance includes ASTM A312 for seamless and welded stainless steel pipes and ASTM A733 for welded and seamless carbon and austenitic stainless steel pipe nipples. The product is RoHS 3 (2015/863/EU) Compliant, ensuring adherence to environmental regulations for hazardous substance restrictions. Compatible with Class 150 fittings and flanges, this component guarantees interoperability within standardized industrial piping systems.
