Professional Applications & Engineering Value

This 3" Schedule 40 galvanized steel threaded pipe nipple delivers exceptional engineering value across industrial fluid handling systems. The hot-dip galvanized coating provides superior protection against corrosion in harsh environments where moisture, chemicals, or outdoor exposure would compromise ordinary steel components. The fully threaded NPT design ensures maximum engagement with mating fittings, eliminating potential leak paths in air, natural gas, oil, steam, and water applications. With its welded construction and standardized 3.068" ID and 3.5" OD dimensions, this nipple maintains consistent wall thickness throughout, preventing weak points that could fail under pressure cycling. The combination of ASTM A53 material specifications and precise NPT threading makes this component ideal for maintenance, repair, and new construction projects requiring reliable, long-lasting pipe connections.

Specification Summary & Compliance

This galvanized steel threaded pipe nipple features precision NPT threads conforming to ASME B1.20.1 standards with Class 2A tolerance for consistent fitting engagement. Manufactured from ASTM A53 galvanized steel with welded construction, the component meets ASTM A733 specifications for commercial welded and seamless carbon steel pipe. The Schedule 40 wall thickness (0.216") ensures proper pressure rating compatibility with Class 125 and 150 fittings. With dimensions of 2 5/8" length, 3.068" ID, and 3.5" OD, this standardized component provides reliable performance across industrial piping systems requiring compliance with major industry standards.
