Test and inspection standards: GB / T13927-2008
American Standard valve test pressure:
Test and inspection standards: API598
20 # steel test pressure temperature – pressure stage
Note: 1, when the operating temperature is the temperature level intermediate values in the table, the available interpolation method to determine the maximum operating pressure.
2, when the main valve parts are made of plastic or non-metallic materials such as rubber mechanical properties and temperature limits in the material below the table, you can not use this form.
3. Users need detailed technical information and sizes, obtained from the manufacturer.
