Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical connection challenges in industrial fluid systems where BSPT × NPT thread compatibility is essential for international equipment integration. The welded construction combined with Schedule 40 wall thickness ensures reliable performance under pressure fluctuations common in air compression, steam distribution, and hydrocarbon processing applications. Engineered for multi-medium handling including natural gas, oil, and water systems, this adapter eliminates the need for multiple specialized fittings while maintaining leak-resistant performance. The corrosion-resistant black coating extends service life in humid or chemically aggressive environments, reducing maintenance frequency and replacement costs in industrial plumbing, process piping, and utility distribution networks.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 thread standards with dimensional compliance to ASTM A53 and ASTM A733 specifications, this pipe nipple maintains precise Class 2A thread tolerances for secure connections. The 1" pipe size with 3" length and 0.13" wall thickness meets Schedule 40 requirements for consistent performance. Compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations ensures environmental safety, while compatibility with Class 150 iron and steel flanges provides standardized integration across industrial piping systems.
