Professional Applications & Engineering Value
This heavy-duty threaded pipe nipple delivers critical performance in industrial fluid and gas systems where reliability is non-negotiable. The seamless black-coated steel construction eliminates weak points common in welded alternatives, providing superior burst resistance for high-pressure applications involving steam, oil, and natural gas. Precision NPT threading ensures consistent engagement with Class 300 and 600 flange systems, while the Schedule 80 wall thickness maintains system integrity under cyclic loading. Engineers specify this component for its predictable performance across temperature variations and aggressive media, reducing maintenance interventions in processing plants, pipeline networks, and industrial machinery.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 for thread geometry and ASTM A106/A53 for material properties, this nipple maintains dimensional accuracy throughout its 4" length. The NPT thread form follows standardized taper specifications for reliable sealing without additional compounds. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) demonstrates environmental responsibility, while the 0.119" wall thickness meets Schedule 80 pressure requirements for industrial fluid systems.
