Professional Applications & Engineering Value
This galvanized steel threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity matter most. The zinc-coated surface actively fights rust in humid or chemical-exposed environments, while the welded construction maintains structural stability under vibration and thermal cycling. Engineered to ASME B1.20.1 and ASTM standards, the NPT threads create secure, leak-resistant joints in air compression systems, natural gas lines, industrial steam applications, and hydraulic oil circuits. The standardized Schedule 40 dimensions ensure seamless integration with existing galvanized iron or steel fittings, reducing installation time and eliminating compatibility concerns in plant maintenance and mechanical system upgrades.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2A NPT threading per ASME B1.20.1, this pipe nipple features precise dimensions (3.068" ID, 3½" OD, 0.216" wall thickness) meeting ASTM A53 and ASTM A733 specifications for material quality and manufacturing consistency. The product is fully compliant with REACH (EC 1907/2006) substance restrictions and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and workplace safety in global industrial applications.
