Professional Applications & Engineering Value

This 316/316L stainless steel threaded pipe nipple addresses critical challenges in industrial fluid transfer systems where corrosion resistance and pressure integrity are paramount. The welded construction combined with NPT threading creates reliable seals that prevent leakage in steam, oil, and gas applications where temperature fluctuations and chemical exposure would degrade inferior materials. Engineers specify this Schedule 40 pipe nipple for its balanced wall thickness that withstands internal pressures while maintaining flow efficiency through the 1.38" ID. The ASTM A733 compliance ensures consistent performance across batch productions, while the male threaded both ends design simplifies maintenance and system modifications in tight spaces common to industrial plants and processing facilities.

Specification Summary & Compliance
