Professional Applications & Engineering Value
This 4" Schedule 80 NPT threaded steel pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. Its seamless black-coated steel construction prevents internal weak points, reducing the risk of leaks and fractures under high-pressure conditions common in air, natural gas, oil, steam, and water applications. The precise NPT threading on both ends ensures tight, secure connections that maintain integrity in dynamic environments, from chemical processing to power generation. By combining thick-wall durability with standardized dimensions, it minimizes installation errors and downtime, providing long-term reliability for Class 300 and 600 flange systems in demanding industrial settings.
Specification Summary & Compliance
This product features a 4" pipe size with Schedule 80 wall thickness (0.337"), NPT thread type on both ends, and complies with ASME B1.20.1 for threading standards. Manufacturing adheres to ASTM A106, A53, and A733 specifications, ensuring dimensional accuracy and material consistency. The nipple is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, confirming its suitability for environmentally conscious industrial applications.
