Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple delivers critical performance in industrial fluid systems where corrosion resistance and pressure integrity are paramount. The zinc-coated surface prevents rust formation in moisture-rich environments, while the Schedule 40 wall thickness (0.216") maintains structural stability under fluctuating pressures. Engineered with NPT threading on both ends, it creates leak-resistant joints in air compression systems, natural gas lines, oil transfer applications, steam distribution, and water supply networks. The welded construction ensures dimensional stability where vibration or thermal expansion occurs, making it ideal for connecting galvanized iron or steel fittings in Class 125/150 systems. This combination of material durability and precise threading solves common installation challenges while meeting rigorous industrial standards.

Specification Summary & Compliance

Manufactured to exacting standards with 3" nominal pipe size, 9" length, and 3.068" ID/3.5" OD dimensions. Threading conforms to ASME B1.20.1 for proper engagement and seal formation. Material certifications include ASTM A53 for steel composition and ASTM A733 for welded construction quality. Suitable for use with Class 125 and 150 fittings and Class 150 flanges, ensuring broad compatibility across industrial piping systems.
