Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid and gas transfer systems. The welded construction combined with Schedule 40 wall thickness provides structural integrity against pressure fluctuations and mechanical stress in air, natural gas, oil, steam, and water applications. The NPT threading on both ends ensures leak-resistant connections that maintain system integrity when paired with iron or steel fittings. This component eliminates the need for multiple specialized connectors, reducing inventory complexity while providing corrosion-resistant performance that minimizes maintenance intervals and replacement costs in aggressive operating environments.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread type conforming to ASME B1.20.1 specifications. The black-coated steel construction meets ASTM A53 material requirements and ASTM A733 specifications for welded and seamless carbon steel pipe nipples. Precision threading ensures proper engagement with Class 125 and 150 iron and steel fittings. The component features a consistent 1 1/2" pipe size with Schedule 40 dimensions (1.61" ID, 1 29/32" OD, 0.145" wall thickness) and 5 1/2" length for reliable system integration.
