Professional Applications & Engineering Value
This 4" Schedule 160 black-coated steel threaded pipe nipple delivers critical engineering solutions for high-pressure industrial systems. Its seamless construction and NPT threading eliminate failure risks in pipelines handling aggressive media like hydraulic fluid, steam, and natural gas. The extra-thick 0.531" wall thickness (Schedule 160) withstands extreme pressures up to Class 3000/1500 fittings, preventing burst incidents in energy and manufacturing plants. The black-coated steel material resists corrosion from moisture and chemicals, reducing maintenance downtime in water treatment or oil refineries. Designed for male threaded connections, it ensures quick, secure installations in complex piping networks, supporting continuous operations with ASME and ASTM certified reliability.
Specification Summary & Compliance
This pipe nipple maintains precise NPT thread specifications per ASME B1.20.1, ensuring compatibility with standard industrial fittings. Manufacturing adheres to ASTM A106, A53, and A733 for material consistency and dimensional accuracy (4" pipe size, 12" length, 3.438" ID, 4 1/2" OD). The product is fully REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliant, confirming adherence to international safety and environmental standards for hazardous substance restrictions.
