Important technical note: the DIN 2690 standard is currently considered obsolete and has been officially replaced by the EN 1514-1:1997-08 regulation. EV Group China specialists recommend using the current version of the standard when designing new piping systems.
Scope of application for DIN 2690 flange gaskets
This regulatory specification establishes the geometric parameters, tolerances, and technical requirements for sealing gaskets intended for the installation of flange connections with flat contact surfaces. The standard covers products designed for operation in systems with a nominal pressure range of PN 1–40.
EV Group China engineers emphasize that the choice of gasket material should be based on the aggressiveness of the operating medium, the temperature range, and the design pressure of the system to ensure the tightness of the connection throughout the entire equipment lifecycle.
