How to reasonably select and use sealing gasket media , temperature, pressure and working conditions should be important factors. For example, when the working pressure is not high, plastic flange docking (PN) is used. For another example, in a working environment with chemical media, different sealing media must be reasonably matched to achieve good results, otherwise unpredictable chemical changes are prone to occur. Therefore, any paradox in the selection of seals will lead to unimaginable consequences. Generally, the gasket structures have the following types for reference: 1. For flange connection a, flat gasket: multi-purpose medium pressure asbestos, oil-resistant asbestos, polytetrafluoroethylene, graphite gasket or reinforced graphite gasket, non-asbestos gasket, metal flat gasket, special metal gasket wait b. Spiral gasket: with outer ring or with inner and outer rings (most commonly used for flat flanges); ring type with inner ring (commonly used for concave and convex flanges); basic type (without inner and outer rings), special for grooved flanges, sealing surface Narrow, flat-welded full-face flange sealing surface is wider, equivalent to a spiral wound gasket with an inner ring and an outer ring. It is necessary to pay attention to which country and standard the flange is. 2. Rotating and pulling shaft seals use a variety of fillers. Such as flexible graphite rings (open and non-open), braided packing (or packing rings) of various materials, internal and external skeleton oil seal YX rings, O-rings, etc. of various materials. 3. Special parts sealing products. Common sealing strips, PTFE ball valve seats, graphite packing rings and rubber butterfly valve rings, etc. What should you pay attention to when installing seals? 1.
