Professional Applications & Engineering Value

This 316/316L stainless steel threaded pipe nipple delivers exceptional performance in demanding industrial settings where corrosion resistance and pressure integrity are critical. The seamless construction eliminates weak points that commonly develop in welded alternatives, while the NPT threaded ends provide secure, standardized connections that prevent leakage in volatile media transfer. Engineered for Class 150 fittings and flanges, this component maintains system integrity in oil and gas pipelines, steam distribution networks, and chemical processing plants where temperature fluctuations and aggressive fluids are present. The combination of ASTM A733 material specifications and ASME B1.20.1 threading standards ensures reliable performance in high-vibration environments, reducing maintenance frequency and downtime.

Specification Summary & Compliance

This 3/8" Schedule 40 pipe nipple features precise NPT threading manufactured to ASME B1.20.1 standards for consistent fit and pressure retention. The component complies with ASTM A733 material specifications for seamless stainless steel pipe, with dimensions of 5½" length, 0.493" ID, and 43/64" OD. Meets RoHS 3 (2015/863/EU) compliance requirements, ensuring environmental safety while maintaining Class 150 pressure ratings for flanges and fittings.
