Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical performance in industrial fluid and gas handling systems. The welded construction combined with NPT threading creates a robust connection point that withstands vibration and pressure fluctuations common in air, natural gas, oil, steam, and water applications. Engineered for 125 and 150 class fittings, this component addresses the need for reliable, leak-resistant junctions in processing plants, manufacturing facilities, and utility systems. The Schedule 40 wall thickness and 24" length provide the structural stability required for extended runs between iron and steel flanges, while the protective coating combats corrosion in humid or chemically aggressive environments, significantly reducing maintenance intervals and system downtime.

Specification Summary & Compliance

This 2" Schedule 40 pipe nipple features NPT threads manufactured to ASME B1.20.1 standards with dimensional compliance to ASTM A53 and ASTM A733 specifications. The component maintains precise internal diameter (2.067") and outer diameter (2 3/8") tolerances with 0.154" wall thickness. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations ensures suitability for industrial applications requiring strict material restrictions.
