Professional Applications & Engineering Value

This super-thick-wall steel threaded pipe nipple delivers critical engineering solutions for industrial fluid and gas transfer systems. The seamless construction eliminates weak points that could fail under extreme pressure cycles, while the NPT thread type provides reliable sealing without additional compounds in most applications. Engineered for air, hydraulic fluid, natural gas, oil, steam, and water service, it withstands thermal expansion, vibration, and corrosive elements that compromise thinner-walled alternatives. The XXH schedule design specifically addresses common failure points in high-pressure hydraulic systems and steam lines, where wall integrity directly impacts system safety and operational continuity. With its 1 1/2" length and male threaded both ends configuration, it enables precise spacing and connection in cramped industrial layouts where custom fabrication isn't practical.

Specification Summary & Compliance

This 3/4" NPT threaded pipe nipple features precision threading manufactured to ASME B1.20.1 standards for consistent engagement and sealing performance. The seamless steel construction complies with ASTM A106 and ASTM A733 material specifications, ensuring mechanical properties suitable for high-pressure applications. With dimensions including 1 1/2" length, 0.434" ID, 1 3/64" OD, and 0.308" wall thickness, it maintains tight tolerances for reliable system integration. The product fully complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, meeting international environmental standards for industrial components.
