Professional Applications & Engineering Value

This heavy-duty Schedule 80 threaded pipe nipple delivers critical performance in demanding industrial fluid systems. The black-coated steel construction provides essential corrosion protection for long-term exposure to aggressive media including oil, steam, and natural gas. Engineered with NPT threading on both ends, it ensures secure, pressure-tight connections in high-vibration environments where leak prevention is paramount. The thick-wall design and welded construction withstand extreme pressure fluctuations in Class 300/600 flange systems, making it ideal for petrochemical, power generation, and industrial processing applications where failure is not an option. Its compliance with ASME B1.20.1 and ASTM standards guarantees dimensional accuracy for trouble-free installation and maintenance.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread specifications per ASME B1.20.1, ensuring proper engagement and sealing performance. The pipe meets ASTM A53 and ASTM A733 material and manufacturing requirements for consistent quality and mechanical properties. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations confirms environmental responsibility and global market acceptability. The 1 1/2" Schedule 80 configuration with 24" length provides standardized dimensions for reliable interchangeability in industrial piping systems.
