The main purpose is to prevent channel clogging of water and steam-water nozzles of steam desuperheaters on the pressure-reducing and desuperheating stations.
The filters of type 13с for steam and water refer to the elements of excess rpressure pipelines.
According to GOST 356-80, the items designed for the ultimate pressure allow their application on operating parameters within the following range:
- at PN 10 MPa – from 10 MPa, 200 °С to 3,6 MPa, 455 °С;
- at PN 25 MPa – from 25 MPa, 200 °С to 9 MPa, 455 °С;
- at PN 6,3 MPa – from 6,3 MPa, 200 °С to 2,3 MPa, 455 °С.
The permissible values of operating pressures and temperatures for the filters may differ from those ones indicated in the table with technical specifications and shall be chosen according to GOST 356-80.
