Professional Applications & Engineering Value

This black-coated steel pipe nipple is engineered to address common failure points in industrial fluid and gas transfer systems. The welded construction and Schedule 80 wall thickness provide robust resistance to internal pressure and mechanical stress, preventing leaks and ruptures in applications involving air, natural gas, oil, steam, and water. The BSPT threaded ends deliver a tapered seal that tightens under pressure, ideal for maintaining integrity in vibrating or thermal cycling environments. Its corrosion-resistant coating further protects against degradation, reducing replacement frequency and total cost of ownership in chemical processing, power generation, and oil & gas infrastructure.

Specification Summary & Compliance

This nipple meets ASTM A733 specifications for welded and seamless steel pipe nipples, ensuring dimensional accuracy and material consistency. The BSPT thread type conforms to standard tapered pipe thread profiles for reliable sealing. It is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, affirming its suitability for industrial use without hazardous substance restrictions. Designed for compatibility with Class 300 and 600 flanges, it supports high-pressure applications while maintaining precise thread engagement for leak-free performance.
