• Optimized flow efficiency with precise 4" diameter and straight design, minimizing pressure drops in piping networks

Professional Applications & Engineering Value

Engineered for high-performance industrial piping systems, this black-coated steel threaded pipe nipple solves critical challenges in chemical processing, power generation, and HVAC applications. The welded construction and Schedule 40 wall thickness (0.237") provide exceptional burst pressure resistance when handling volatile media including steam, oil, and natural gas. Precision NPT threading per ASME B1.20.1 ensures leak-free connections in Class 125/150 iron and steel fittings, while the protective black coating combats corrosion in humid or chemical-exposed environments. Its 60" length and 4" diameter make it ideal for long-span connections in plant piping, reducing joint counts and potential failure points.
