Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical challenges in industrial fluid handling systems. The welded construction combined with NPT threading creates reliable, pressure-tight seals that withstand thermal cycling and mechanical stress. Engineered for air, natural gas, oil, steam, and water service, the protective coating resists corrosion while maintaining Schedule 40 pressure ratings. Its standardized 4" diameter and 10" length make it ideal for maintenance, repair, and new installations in chemical plants, manufacturing facilities, and utility systems where connection integrity is paramount.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 specifications for NPT thread form with Class 2A tolerances. Meets material requirements of ASTM A53 and ASTM A733 standards. Compatible with 125 and 150 class fittings in iron and steel materials. The 4.026" ID and 4 1/2" OD with 0.237" wall thickness maintain consistent flow characteristics while providing structural reliability in industrial piping systems.
