Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple solves critical connection challenges in industrial fluid and gas systems. The welded construction combined with NPT threading on both ends creates a robust pressure boundary that withstands vibration and thermal cycling in air, natural gas, oil, steam, and water applications. The protective black coating provides an additional barrier against corrosion in humid or chemically aggressive environments, while the Schedule 40 wall thickness ensures dimensional stability under pressure fluctuations. Engineered for Class 125 and 150 iron/steel flanges, this nipple delivers reliable performance in piping systems requiring male threaded connections with long-term serviceability.
Specification Summary & Compliance
Manufactured to precise dimensional standards with NPT thread form per ASME B1.20.1, this pipe nipple maintains Class 2A thread tolerances for consistent sealing performance. The component meets ASTM A53 and ASTM A733 material specifications for pressure-rated applications. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) ensures environmental responsibility and workplace safety. With 1/2" pipe size, 0.622" ID, 27/32" OD, and 0.109" wall thickness, this 20-inch long nipple provides exact dimensional consistency for industrial piping layouts.
