Metal ring gaskets can be classified into two types: octagonal gaskets and oval gaskets. The main difference between these two types of gaskets is their cross-sectional shape.
So when we found out that octagonal gaskets can be reused, did you also wonder if oval gaskets can also be used? Actually, oval gaskets cannot be reused!
Firstly, the octagonal gasket matches the flange groove in a surface contact manner, and its sealing performance is not as good as that of the oval gasket. However, it can be reused because its cross-section is composed of straight lines and is easy to process; The oval gasket and flange groove exhibit line contact and good sealing performance, but due to their high processing accuracy requirements and manufacturing costs.
There are many types of RTJ gaskets, including R Gasket,RX Gasket,BX Gasket, SBX Gasket,IX Gasket,and various customized products.We will do more sharing about ring joint gasket.
