Professional Applications & Engineering Value

This 4" Schedule 40 galvanized steel threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. The zinc-coated steel material provides excellent corrosion resistance, preventing premature failure in environments exposed to moisture, chemicals, or outdoor elements. Its welded construction and NPT thread type ensure a tight seal against leaks in high-pressure applications involving air, natural gas, oil, steam, or water. The standardized 24" length and straight shape simplify pipeline assembly, reducing installation time and labor costs. By meeting ASME B1.20.1 and ASTM specifications, this threaded pipe nipple delivers reliable performance in HVAC, plumbing, and industrial processing systems, minimizing downtime and maintenance expenses.

Specification Summary & Compliance

This product features precise NPT threading per ASME B1.20.1 standards, ensuring compatibility with Class 125 and 150 galvanized iron or steel fittings. The 4" pipe size with Schedule 40 dimensions (ID: 4.026", OD: 4 1/2", Wall Thickness: 0.237") maintains consistent tolerances for secure connections. Manufacturing complies with ASTM A53 (standard for seamless and welded steel pipe) and ASTM A733 (covering welded and seamless carbon steel pipe), with material and construction meeting industry requirements for pressure and mechanical properties. The galvanized finish supports RoHS and REACH environmental directives by limiting hazardous substances.
