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 exceptional burst pressure resistance, preventing system failures in air, natural gas, oil, steam, and water applications. The BSPT × NPT threaded connections address cross-standard compatibility challenges, enabling seamless integration between international piping networks while maintaining Class 150 pressure ratings. The protective black coating significantly reduces corrosion-induced degradation, extending maintenance intervals in chemical exposure and outdoor installations. Engineered for iron and steel fitting systems, this straight nipple eliminates leakage points through precision-machined threads that meet rigorous ASME B1.20.1 dimensional standards.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 threading specifications with ASTM A53 and ASTM A733 material standards ensuring consistent dimensional accuracy and mechanical properties. The 1" pipe size with Schedule 40 wall thickness (0.13") maintains pressure integrity while the 4" length provides optimal connection spacing. Fully compliant with REACH (EC 1907/2006) substance restrictions and RoHS 3 (2015/863/EU) directives for hazardous material-free industrial components.
