Professional Applications & Engineering Value

This 3/4 inch Schedule 40 stainless steel threaded pipe nipple delivers critical performance in industrial fluid and gas handling systems. Its 304/304L stainless steel composition resists pitting and oxidation, while the NPT threaded end ensures pressure-tight seals in steam, oil, and natural gas applications. The butt weld/socket connect alternative allows for permanent, high-strength joints in rigid piping networks. Engineered to ASTM A312 specifications, it eliminates thread galling and withstands thermal expansion, reducing maintenance downtime in chemical plants, HVAC systems, and process manufacturing facilities.

Specification Summary & Compliance

Manufactured to Class 2A thread tolerances per ASME B1.20.1 with precise dimensions: 2-1/2" length, 0.824" ID, and 1-3/64" OD. Complies with ASTM A312 for seamless/welded pipe and ASTM A733 for welded fittings. Meets RoHS 3 (2015/863/EU) requirements and is rated for Class 150 service across compatible stainless steel flanges and fittings.
