Professional Applications & Engineering Value

This 304/304L stainless steel threaded pipe nipple delivers exceptional performance in industrial fluid transfer systems where corrosion resistance and pressure integrity are critical. The welded construction combined with NPT threading creates reliable seals for air, natural gas, oil, steam, and water applications, preventing costly leaks in processing equipment and piping networks. Engineered to ASTM A312 standards with precise Schedule 40 dimensions, this adapter maintains consistent flow characteristics while withstanding thermal cycling and chemical exposure. The male threaded connection and socket connect options provide installation flexibility for maintenance and system modifications, reducing downtime in industrial facilities, chemical plants, and energy infrastructure projects.

Specification Summary & Compliance

Manufactured to precise dimensional standards with NPT thread form per ASME B1.20.1, this pipe nipple maintains Class 2A thread tolerances for secure connections. The component meets ASTM A312 and ASTM A733 specifications for material quality and manufacturing consistency, with full compliance to RoHS 3 (2015/863/EU) environmental directives. The 1 1/2" size with Schedule 40 wall thickness (0.145") ensures compatibility with standard industrial piping systems while the 3" length provides optimal engagement for threaded connections in confined spaces.
