Issues related to wound gaskets

2020-04-09View Original

Thread Content

In HG20610, the basic type of winding gasket is not used on RF-face flanges. But what standard determines the dimensions of the basic type gaskets for RF faces in the current market? Which standard does the size of the basic type of metal wound gasket used with raised-face flanges follow?

Then for the RF flange, should an Type A metal gasket be used? Should the dimensions be based on those of Type C and Type D?

1. The basic version cannot be used on RF sealing surfaces; 2. The sizes are all the same ; 3. If cost savings are really necessary, use the D1221 model; it won’t cost much more
