316L Corrosion Resistant Weld Neck Flange

Feature: Long-neck flanges (also called weld neck flanges) have an extended neck that integrates with the pipe, distributing stress evenly and enhancing overall strength. This design avoids stress concentration at the connection, making them highly resistant to pressure.

Application: Widely used in high-pressure pipelines such as oil and gas transmission lines, where the pipeline often bears internal pressures above 10MPa. The long neck’s stress-dispersing effect prevents leakage and ensures safe operation under extreme pressure.
