Professional Applications & Engineering Value
This heavy-duty 3" Schedule 40 steel threaded pipe nipple delivers critical performance where standard fittings fail. The welded construction and black-coated steel material provide exceptional resistance to corrosion and mechanical stress in demanding fluid transfer systems. Engineered with NPT male threading on one end and socket weld connection on the other, it solves installation challenges in tight spaces while maintaining pressure integrity for air, natural gas, oil, steam, and water applications. The ASTM A53 compliant manufacturing ensures consistent wall thickness and diameter tolerances, preventing system failures in industrial piping networks requiring reliable adapter solutions between threaded and welded components.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 specifications for precise NPT thread form with Class 2A tolerances. Meets ASTM A53 and ASTM A733 material standards for welded steel pipe applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensions: 3" nominal pipe size, 12" length, 3.068" ID, 3½" OD, 0.216" wall thickness. Suitable for iron and steel fittings rated Class 125/150.
