Professional Applications & Engineering Value

This 3-inch Schedule 40 stainless steel pipe nipple delivers critical engineering solutions for industrial fluid and gas systems. The 304/304L stainless steel material provides exceptional resistance to corrosion and oxidation, making it ideal for steam, chemical, and marine applications where environmental factors degrade inferior materials. The innovative threaded × butt weld connection design addresses installation flexibility challenges, allowing contractors to choose the most efficient joining method for specific system requirements. With NPT threading on one end and socket connection capability, this adapter eliminates leakage points in high-pressure oil, gas, and steam lines while maintaining ASTM A312 dimensional precision. The welded construction ensures structural integrity where vibration or thermal cycling would compromise threaded-only alternatives.

Specification Summary & Compliance

This precision-engineered pipe nipple features Class 150 compatibility with NPT threading manufactured to ASME B1.20.1 standards. The component meets stringent ASTM A312 and ASTM A733 specifications for stainless steel pipe and welded/unwelded fittings, ensuring dimensional accuracy and material consistency. With a 3.068" ID and 3½" OD maintaining Schedule 40 wall thickness of 0.216", this straight configuration adapter is RoHS 3 (2015/863/EU) compliant for environmental responsibility in industrial applications.
