Professional Applications & Engineering Value

This 1" Schedule 40 stainless steel threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity are paramount. The 304/304L stainless steel composition prevents rust and chemical degradation when handling aggressive media including steam, oil, and natural gas. Its NPT male threading on both ends creates secure, leak-resistant joints in 150 class fitting systems, while the 18" length provides necessary reach in complex piping layouts. The welded construction ensures consistent wall thickness (0.133") throughout the straight pipe nipple, maintaining flow characteristics (1.049" ID) without turbulence. Engineers specify this component for its proven reliability in industrial plumbing, process lines, and utility distribution where ASTM A733 and ASME B1.20.1 compliance eliminates installation uncertainties.

Specification Summary & Compliance

Manufactured to ASTM A733 and ASME B1.20.1 specifications ensuring precise NPT thread dimensions and Schedule 40 wall thickness (0.133"). The 304/304L stainless steel construction meets chemical composition requirements with 1.049" ID and 1 5/16" OD maintained throughout the 18" length. Fully compliant with RoHS 3 (2015/863/EU) regulations, suitable for 150 class fittings and flanges in air, natural gas, oil, steam, and water service.
