Professional Applications & Engineering Value

This 4" Schedule 40 black-coated steel pipe nipple delivers exceptional engineering value by addressing common industrial challenges such as corrosion under insulation and connection versatility. The black-coated steel material significantly reduces oxidation and wear in harsh media like steam, oil, and natural gas, extending maintenance intervals. Its unique threaded NPT × butt weld/socket connect design allows for adaptable installation in confined spaces or when transitioning between threaded and welded systems, minimizing downtime. Engineered to ASTM A53 and A733 specifications, it ensures consistent dimensional accuracy (4.026" ID, 4 1/2" OD) and pressure resilience, making it ideal for industrial piping networks requiring reliable, leak-free performance.

Specification Summary & Compliance

This pipe nipple adheres to Class 2A threading tolerances per ASME B1.20.1 for NPT ends, with precise dimensions: 8" length, 4.026" ID, and 0.237" wall thickness. It conforms to ASTM A53 and ASTM A733 manufacturing standards for material quality and welding integrity. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and regulatory acceptance in global markets.
