Technical features of the DIN 28403 standard
The DIN 28403 standard regulates the design parameters and operational characteristics of small flange connections designed for vacuum systems. This equipment is optimized for operation in both high and low vacuum conditions, ensuring tightness and reliability at pressure differentials of up to 1.5 bar.
The quick-release architecture of the DIN 28403 flanges from EV Group China significantly reduces installation and maintenance time for vacuum pipelines. The technology allows for the installation of elements in any spatial orientation, which is critical for integration into complex technological installations.
Flange connection form A
Transition flange connection form B
A standard quick-release connection assembly according to DIN 28403 consists of:
- Clamping ring (clamp);
- Flange elements;
- Centering ring;
- O-ring seal (elastomer);
- Transition adapters for joining dissimilar pipe materials.
