Professional Applications & Engineering Value

This 1 1/2" NPT threaded pipe nipple addresses critical leakage and corrosion challenges in industrial piping systems. The 316/316L stainless steel material provides exceptional resistance to pitting and chemical attack, while the PTFE thread sealant pre-applied during manufacturing creates an immediate, reliable seal that withstands thermal expansion and pressure fluctuations. Engineers value its Schedule 40 wall thickness and welded construction for maintaining burst strength in steam, oil, and natural gas applications, eliminating downtime from seal failures. The male threaded both ends design with standardized NPT threading ensures compatibility with existing Class 150 stainless steel fittings, streamlining maintenance and new installations across chemical processing, power generation, and HVAC systems.

Specification Summary & Compliance

This pipe nipple maintains precise NPT thread dimensions per ASME B1.20.1 with a 1.61" ID and 0.145" wall thickness for consistent flow characteristics. Manufacturing complies with ASTM A733 for welded and seamless carbon and alloy steel pipe nipples, ensuring mechanical properties and dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for use with 316 stainless steel fittings and flanges rated Class 150, providing regulatory adherence for global industrial applications.
