Professional Applications & Engineering Value

Engineered for demanding fluid handling systems, this 304/304L stainless steel threaded pipe nipple solves critical challenges in industrial piping networks. The NPT threaded end creates secure, pressure-tight joints that prevent costly leaks in compressed air lines, steam distribution, and hydrocarbon processing. Its welded construction and Schedule 40 rating provide exceptional resistance to vibration-induced fatigue and pressure surges common in oil/gas applications. The socket connect design enables rapid installation in confined spaces while maintaining Class 150 pressure integrity. With inherent corrosion resistance against water and chemical media, this ASTM A312 compliant component delivers long-term reliability in HVAC, process piping, and industrial plant maintenance operations.

Specification Summary & Compliance

This 1/2" NPT threaded pipe nipple maintains precise dimensional tolerances per ASME B1.20.1 threading standards with Schedule 40 wall thickness (0.109") ensuring consistent fit-up. Manufacturing complies with ASTM A312 for seamless/welded pipe specifications and ASTM A733 for welded/unwelded fittings. The component is RoHS 3 (2015/863/EU) Compliant and suitable for systems operating at Class 150 pressure ratings with 304/304L stainless steel providing material traceability for quality assurance programs.
