Professional Applications & Engineering Value

This 4" Schedule 40 galvanized steel threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity matter most. The hot-dip galvanized coating creates a protective barrier against rust and chemical degradation, significantly extending service life in harsh industrial environments. Engineered with NPT threading on both ends, it ensures leak-proof connections in air, natural gas, oil, steam, and water systems while maintaining full compatibility with galvanized iron and steel fittings. The welded construction and standard wall thickness provide exceptional structural strength to withstand vibration, pressure surges, and mechanical stress in industrial piping networks, reducing maintenance frequency and system downtime.

Specification Summary & Compliance

This 4" Schedule 40 pipe nipple features precise NPT threading manufactured to ASME B1.20.1 standards, ensuring proper engagement and sealing performance. The galvanized steel construction complies with ASTM A53 for material quality and ASTM A733 for welded and seamless carbon steel tubing specifications. Dimensional accuracy includes 4.026" ID, 4-1/2" OD, and 0.237" wall thickness with male threaded connections on both ends. Suitable for use with Class 125 fittings and Class 150 flanges, this component meets industry standards for pressure rating and material compatibility in industrial fluid handling applications.
