Overview
Notation:
1. Select the appropriate material according to the use occasions and requirements;
2. Select the suitable interface series according to the use pressure and medium;
3. Flanges of the same specification series should be selected uniformly, and the specifications of flanges under different nominal pressures should be the same;
4. Selection of specifications should be determined according to the nominal diameter and thickness of the pipeline;
5. Sealing surfaces of square flanges should be flat and their external profiles should meet the standard requirements;
6. Selection of bolts should meet the requirements of the corresponding standards.
