Professional Applications & Engineering Value

This 304/304L stainless steel threaded pipe nipple addresses critical industrial challenges by combining welded construction with dual connection styles—NPT threaded on one end and butt weld/socket connect on the other. Engineered for demanding media including air, natural gas, oil, steam, and water, it prevents corrosion-induced failures and maintains integrity under thermal cycling. The Schedule 40 profile and precise Class 2A threading (per ASME B1.20.1) ensure leak-free performance in high-vibration environments, reducing maintenance downtime in pipelines, processing plants, and energy systems. By meeting ASTM A312 material specs, it delivers consistent strength for industrial pipe fittings that require reliability and compliance.

Specification Summary & Compliance

This product adheres to ASTM A312 for material composition and ASTM A733 for welding standards, with threading conforming to ASME B1.20.1 for Class 2A tolerance. Dimensions include a 1/2" NPT threaded end, 5-1/2" length, 0.622" ID, and 27/32" OD. It is RoHS 3 (2015/863/EU) compliant, ensuring environmental safety, and designed for use with Schedule 40, Class 150 fittings in industrial fluid and gas applications.
