ASME EN DN2000 PN10-100 Stainless Steel Plate Flange
Production Standard：ASME B16.5, ASME B16.47, EN 1092-1 Type 01, DIN 2573~2576, ISO 7005-1, JIS B2220, GOST 12820-80, API 6A, AS/NZS 4087, GB/T 9124.1-2019.
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.
