Professional Applications & Engineering Value
This black-coated steel pipe nipple is engineered to address common industrial challenges like corrosion, high-pressure leaks, and installation complexity. The welded construction and Schedule 40 wall thickness provide exceptional durability against internal pressures and mechanical stress in systems conveying air, natural gas, oil, steam, or water. The combination of NPT threaded and butt weld connections allows for secure, versatile integration into steel or iron piping networks, reducing the need for multiple adapters and minimizing potential failure points. Ideal for industrial plants, energy facilities, and plumbing applications, it ensures reliable performance under demanding conditions while adhering to ASTM A733 and other key standards.
Specification Summary & Compliance
This pipe nipple meets ASME B1.20.1 for NPT thread specifications and ASTM A53 for material quality, ensuring precise Class 2A threading tolerances and consistent dimensions (4" pipe size, 60" length, 4.026" ID, 4 1/2" OD). It is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU), confirming its suitability for regulated industrial environments.
