Weld Neck Flange
High-pressure/high-temperature flange with tapered hub, welded to pipe end for strong, leak-tight connections.
Description
A weld neck flange is designed to be welded to the end of a pipe for high-pressure and high-temperature applications. It features a tapered hub that provides a gradual transition from pipe to flange, reducing stress concentrations.
Used in oil and gas, petrochemical, chemical processing, power generation, and heavy industries. Available in pressure classes from 150LB to 2500LB.
