Professional Applications & Engineering Value
This galvanized steel threaded pipe nipple is engineered to solve critical challenges in industrial piping systems. The zinc coating provides a sacrificial layer that significantly reduces rust and corrosion, a common failure point in systems handling air, natural gas, oil, steam, and water. Its welded construction and NPT thread type ensure a robust, pressure-tight seal that prevents leaks in high-vibration applications. Designed for use with Class 150 flanges and galvanized iron or steel fittings, this 4-inch pipe nipple offers a reliable, long-lasting connection solution that minimizes maintenance downtime and replacement costs in commercial and industrial settings.
Specification Summary & Compliance
This product features a 1/2" Schedule 40 pipe size with a 4-inch length, 0.622" ID, and 0.109" wall thickness. It is manufactured with NPT (National Pipe Taper) threads on both ends, conforming to standard dimensional and threading tolerances. The nipple is constructed from galvanized steel and complies with ASME B1.20.1 for pipe threads, ASTM A53 for specification of pipe, steel, black and hot-dipped, zinc-coated, welded and seamless, and ASTM A733 for welded and seamless carbon steel and austenitic stainless steel pipe nipples.
