Professional Applications & Engineering Value

This heavy-duty threaded pipe nipple solves critical industrial challenges by combining black-coated steel construction with Schedule 80 wall thickness to prevent corrosion and withstand high-pressure applications. The seamless design eliminates potential failure points in piping systems handling aggressive media like oil and steam, while the NPT threading ensures leak-tight connections in 300/600 flange class configurations. Engineers specify this component for its reliable performance in petrochemical, HVAC, and industrial plumbing applications where threaded pipe connections must maintain integrity under thermal cycling and mechanical stress. The combination of ASTM A106/A53 materials with precision manufacturing creates a robust solution for fluid transfer systems requiring durable, maintenance-free operation.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 specifications for NPT thread form with dimensional compliance to ASTM A106, ASTM A53, and ASTM A733 standards. The component features precise threading with standard pipe tolerances for Class 300/600 flange applications. Fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental safety and industrial suitability. The 4" pipe size with Schedule 80 wall thickness (0.337") provides consistent performance across the 8" length with threaded both ends configuration.
