Professional Applications & Engineering Value
This 316 stainless steel threaded pipe nipple delivers critical corrosion protection in aggressive processing environments where standard carbon steel components fail. The NPT threaded both ends design with Schedule 40 wall thickness maintains system integrity under pressure fluctuations in oil, gas, and steam applications. Welded construction enhances structural reliability in high-temperature operations, while the ASTM A733 compliance ensures consistent dimensional accuracy across industrial piping layouts. Engineers specify this solution for chemical processing, marine installations, and power generation systems where material compatibility and RoHS 3 compliant certification are mandatory for international projects.
Specification Summary & Compliance
Manufactured to ASTM A733 standards with NPT thread form per ASME B1.20.1 specifications. Dimensions include 4" pipe size, 4.026" ID, 4½" OD, 0.237" wall thickness, and 8" length with Class 2A thread tolerances. Compliant with RoHS 3 (2015/863/EU) directives and suitable for 150 class fittings and flanges in 316/316L stainless steel systems.
