Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple solves critical piping challenges in industrial fluid systems where corrosion resistance and pressure integrity are paramount. The welded construction combined with NPT threads creates a robust connection point that withstands thermal expansion and mechanical stress in air, gas, oil, steam, and water applications. Engineers specify this component for its Schedule 40 wall thickness which maintains burst pressure safety margins while the black coating provides essential protection against rust in humid or chemical environments. Its compliance with ASME B1.20.1 threading standards ensures perfect compatibility with existing iron and steel fittings, reducing installation time and eliminating leakage risks at connection points.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 for precise NPT thread dimensions and ASTM A53/A733 material standards. Features Class 2A thread tolerances for reliable engagement with mating components. The 24" length maintains straightness tolerance per industrial pipe specifications. Fully compliant with REACH (EC 1907/2006) substance restrictions and RoHS 3 (2015/863/EU) directives for hazardous material-free construction.
