Professional Applications & Engineering Value

This black-coated steel pipe nipple is engineered to solve critical connection challenges in industrial fluid and gas handling systems. Its threaded to butt weld adapter design eliminates the need for multiple fittings, reducing potential leak points and installation time in air, natural gas, oil, steam, and water lines. The welded construction and Schedule 40 wall thickness provide exceptional burst pressure resistance, while the NPT threaded end ensures a reliable seal in high-vibration environments. Made from compliant ASTM A53/A733 steel, it delivers consistent performance in petrochemical, manufacturing, and utility applications where corrosion resistance and regulatory adherence are paramount.

Specification Summary & Compliance

This pipe nipple features NPT threads per ASME B1.20.1 with standard Class 2A tolerances for precise engagement. Manufactured to ASTM A53 and ASTM A733 specifications for material and welding quality, it maintains dimensional accuracy with 3/4" pipe size, 2" length, and 0.113" wall thickness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in global industrial markets.
