Professional Applications & Engineering Value

This 6" Schedule 40 galvanized steel threaded pipe nipple delivers critical performance in industrial piping systems where corrosion resistance and pressure integrity are paramount. The hot-dip galvanized coating effectively combats rust and degradation when handling aggressive media like steam, oil, or natural gas, significantly reducing maintenance frequency and downtime. Its NPT threaded both ends design facilitates quick, secure connections to galvanized iron or steel fittings in Class 125 and 150 configurations, maintaining system integrity across HVAC, process piping, and utility networks. Engineered with welded construction and standardized dimensions, it ensures reliable flow characteristics (6.065" ID) while withstanding thermal expansion and mechanical stresses common in industrial pipe fittings applications.

Specification Summary & Compliance

This pipe nipple features NPT threads manufactured to ASME B1.20.1 specifications, ensuring precise thread form and engagement. The galvanized steel material complies with ASTM A53 for structural quality and ASTM A733 for welded and seamless carbon and alloy steel tube requirements. With a standard Schedule 40 wall thickness (0.28") and 6 1/2" length, it maintains dimensional consistency for Class 125 and 150 flange systems. The product meets industry standards for pressure ratings and is suitable for applications requiring RoHS and REACH environmental compliance.
