Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple delivers critical engineering solutions for industrial fluid and gas handling systems. The welded construction combined with NPT threading provides exceptional structural stability against pressure surges and thermal cycling in demanding applications. The zinc coating actively prevents rust formation in moist environments, making it ideal for steam condensate lines, compressed air systems, and outdoor piping exposed to weather elements. Its compatibility with multiple media types – including natural gas, oil, and water – eliminates the need for specialized components across different plant sections. The 72-inch length significantly reduces installation time and potential failure points in long-distance piping runs, while the standardized dimensions ensure perfect fitment with galvanized iron and steel fittings rated for Class 125 and 150 service.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread form compliant with ASME B1.20.1 specifications. The galvanized steel material meets ASTM A53 requirements for pressure applications, while construction adheres to ASTM A733 for welded and seamless tubing. Dimensions include 3" nominal pipe size with Schedule 40 wall thickness (0.216"), 3.068" ID, and 3½" OD. Suitable for flange classes up to 150 and fitting classes 125/150. The zinc coating provides corrosion protection in accordance with industrial standards for extended service life in demanding environments.
