Professional Applications & Engineering Value

This black-coated steel pipe nipple solves critical connectivity challenges in industrial fluid transfer systems. The NPT threaded × butt weld adapter configuration enables seamless transitions between threaded assemblies and welded pipelines, eliminating the need for multiple fittings in air, natural gas, oil, steam, and water applications. The welded construction combined with Schedule 40 wall thickness (0.203") provides exceptional pressure containment while the protective coating resists corrosion from aggressive media. Engineers value this male threaded pipe adapter for its ability to maintain system integrity in high-vibration environments where leak prevention is paramount, making it ideal for petrochemical plants, power generation facilities, and industrial processing systems requiring reliable socket weld connections.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread specifications per ASME B1.20.1 ensuring proper sealing engagement. The 2 1/2" pipe size with Schedule 40 dimensions maintains precise tolerances for consistent performance. Material compliance with ASTM A53 and ASTM A733 specifications guarantees mechanical properties and manufacturing quality. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives confirms suitability for regulated industrial markets. Compatible with Class 125 and 150 iron/steel flanges for broad application across standard industrial piping systems.
