Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid handling systems. The welded construction combined with NPT threading creates permanent, high-pressure joints that prevent leakage in compressed air lines, hydraulic oil circuits, and steam distribution networks. The protective coating significantly reduces oxidation and corrosion in humid or chemical-exposed environments, while the Schedule 40 wall thickness maintains pressure integrity across temperature variations. Engineered to interface seamlessly with iron and steel fittings for Class 125 and 150 applications, this component eliminates compatibility concerns in plant maintenance and system upgrades, reducing downtime and replacement frequency across multiple industrial sectors.

Specification Summary & Compliance

This precision-manufactured pipe nipple features NPT thread form conforming to ASME B1.20.1 dimensional standards with Class 2A thread tolerances for reliable engagement. Manufacturing compliance includes ASTM A53 for material composition and ASTM A733 for welded and seamless carbon and austenitic stainless steel pipe nipples. The product meets industry standards for pressure-rated applications with iron and steel fittings while maintaining dimensional accuracy with 0.269" ID, 13/32" OD, and 0.068" wall thickness throughout the 10" straight configuration.
