- Leak-proof connections ensured by precision NPT threading on both ends, conforming to ASME B1.20.1 standards.
- Enhanced durability and strength from seamless steel manufacturing, reducing risk of fractures under stress.
- Broad fluid compatibility for safe use with air, oil, water, steam, natural gas, and hydraulic fluids.
- Reliable industrial compliance meeting ASTM A106, A53, and A733, plus REACH and RoHS 3 environmental standards.
- Easy installation and replacement with standard 4" pipe size and male threaded ends, simplifying maintenance.
Professional Applications & Engineering Value
This 4" NPT threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas systems. The seamless black-coated steel construction prevents internal weak points, minimizing failure risks in high-vibration or thermal cycling applications like steam lines and hydraulic systems. With a Schedule 160 wall thickness and compliance to ASME B1.20.1 threading standards, it maintains integrity under extreme pressures, reducing downtime in oil, gas, and water pipelines. The male threaded both ends design ensures a secure fit in Class 3000 steel fittings and Class 1500 flanges, providing a robust solution for plant engineers seeking longevity and safety in demanding environments.
Specification Summary & Compliance
This pipe nipple features precise NPT threads per ASME B1.20.1, with dimensions including 4" pipe size, 8" length, 3.438" ID, and 4 1/2" OD. Manufactured from seamless steel meeting ASTM A106, A53, and A733 specifications, it is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental and safety standards are upheld for global industrial use.
