Professional Applications & Engineering Value

This thick-wall stainless steel threaded pipe nipple addresses critical industrial challenges where corrosion resistance and pressure integrity are paramount. The seamless 316/316L construction prevents internal crevices, minimizing contamination risks in sanitary or high-purity systems like pharmaceutical or food processing lines. Its NPT thread form, conforming to ASME B1.20.1, ensures reliable sealing in dynamic applications such as hydraulic fluid power units and steam distribution networks, where vibration-induced loosening can cause costly downtime. Engineers value its ability to maintain wall thickness under Schedule 80 specifications, providing a safety margin in oil and gas pipelines or compressed air systems operating at 3000-class pressures, while the male threaded both ends design simplifies maintenance in confined spaces.

Specification Summary & Compliance

This nipple meets ASME B1.20.1 for NPT thread dimensions and ASTM A733 for seamless welded and seamless stainless steel pipe specifications, ensuring consistent thread engagement and material properties. Dimensions include 3/4" pipe size, 2 1/2" length, 1 3/64" OD, and 0.154" wall thickness per Schedule 80 requirements. It is RoHS 3 (2015/863/EU) Compliant and suitable for use with 3000-class fittings and Class 300/600 flanges, guaranteeing interoperability in standardized industrial piping systems.
