Professional Applications & Engineering Value

This 316/316L stainless steel threaded pipe nipple delivers exceptional performance in demanding industrial systems where corrosion resistance and pressure integrity are critical. The NPT threaded ends create secure, leak-resistant joints in air, natural gas, oil, steam, and water applications, while the welded construction ensures structural stability under thermal cycling and vibration. Engineers specify this Schedule 40 pipe nipple for chemical processing, oil and gas pipelines, and power generation systems where ASTM A733 compliance guarantees material consistency and the 10 1/2" length provides optimal spacing between connections. The combination of male threaded design and corrosion-resistant properties makes it ideal for permanent installations requiring minimal maintenance in aggressive environments.

Specification Summary & Compliance

This 1 1/4" Schedule 40 threaded pipe nipple features NPT threading on both ends with standard pipe dimensions (OD: 1 21/32", ID: 1.38", Wall: 0.14"). Manufactured in compliance with ASTM A733 for welded and seamless pipe standards and ASME B1.20.1 for pipe thread specifications. The product meets RoHS 3 (2015/863/EU) compliance requirements and is compatible with Class 150 flanges and fittings made from 316/316L stainless steel.
