How is the pressure rating of the flange divided

2021-09-02 08:48:48   Comment:0 Hits:
  Common flanges are used in different places, so the pressure grade is different to a certain extent. For example, large stainless steel flanges are mainly used in high temperature resistant pipelines in chemical engineering, so it is necessary to

  The material has high requirements for pressure bearing function.

  Therefore, customers often require forged flanges. Because the data is forged, the arrangement density is improved and its pressure bearing ability is enhanced.

  There are clear grade requirements for the compression resistance of large stainless steel flanges in domestic and world specifications. Large stainless steel flanges are generally divided into PN25, pn6, PN10, PN16, PN25, PN40, etc

  Wait. PN10 and PN16 are the most commonly used.
