Professional Applications & Engineering Value
This black-coated steel pipe nipple solves critical challenges in industrial fluid handling systems where corrosion resistance and connection reliability are paramount. The welded construction combined with NPT threading creates a robust interface that withstands vibration and pressure fluctuations in air, gas, oil, steam, and water applications. Engineers benefit from the threaded × butt weld configuration that allows seamless integration between different piping components while maintaining ASME B1.20.1 dimensional accuracy. The Schedule 40 wall thickness provides optimal strength-to-weight ratio for heavy-duty processing plants, chemical facilities, and industrial plumbing systems where failure is not an option.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 threading standards with ASTM A53 and ASTM A733 material specifications. Features precise NPT thread form on one end with 4" pipe size, 4.026" ID, and 4 1/2" OD. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives for industrial safety and regulatory requirements.
