Professional Applications & Engineering Value

This heavy-duty Schedule 80 stainless steel threaded pipe nipple delivers critical performance advantages in industrial piping systems where corrosion resistance and pressure integrity are paramount. The seamless 316/316L stainless steel construction eliminates weld weaknesses that commonly fail in high-cycle applications, while the NPT threaded ends provide reliable, standardized connections that resist vibration loosening. Engineers specify this thick-wall pipe nipple for chemical processing, hydraulic power units, and steam distribution systems where corrosion-resistant properties prevent material degradation from aggressive media. The 4" length offers optimal spacing flexibility in compact plumbing arrangements, making it ideal for instrumentation connections, pump interfaces, and valve manifolds requiring durable, maintenance-free performance.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 for precise NPT thread form and ASTM A733 for consistent mechanical properties, this 2" Schedule 80 pipe nipple maintains Class 2A thread tolerances for leak-proof assembly. The seamless construction with 0.218" wall thickness ensures uniform strength throughout the 4" length, while compliance with RoHS 3 (2015/863/EU) demonstrates environmental responsibility. Suitable for 3000 PSI fitting classes and 300/600 PSI flange systems, this component meets rigorous industrial standards for pressure piping applications.
