Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple delivers critical engineering solutions for industrial fluid handling systems. The zinc-coated construction provides essential corrosion protection in harsh environments where moisture and chemicals are present, significantly reducing maintenance frequency and replacement costs. The precision NPT threading on both ends ensures secure, leak-resistant connections in high-pressure applications involving air, natural gas, oil, steam, and water. The Schedule 40 wall thickness (0.145") combined with welded construction offers superior burst strength, making it ideal for industrial plumbing, process piping, and mechanical systems requiring reliable performance under varying pressure conditions. This 4-inch male threaded pipe serves as a crucial component in connecting galvanized iron and steel fittings across multiple industrial sectors.

Specification Summary & Compliance

This 1 1/2" Schedule 40 galvanized steel threaded pipe nipple features NPT (National Pipe Taper) threads conforming to ASME B1.20.1 standards for proper sealing engagement. The product meets ASTM A53 specifications for seamless and welded steel pipe, and ASTM A733 for welded and seamless carbon steel pipe nipples. With dimensions of 4" length, 1.61" ID, and 1 29/32" OD, this component is engineered for use with Class 125 and 150 fittings in industrial piping systems. The galvanized surface treatment provides corrosion resistance while maintaining compliance with industry pressure and material standards.
