Metal ring gasket is a solid metal gasket processed from metal material with a cross-sectional shape of octagonal or elliptical. It contacts the inner and outer sides of the flange trapezoidal groove through its own gasket, and finally forms a seal by compression, with a certain radial self tightening sealing effect.
Metal ring gasket are divided into two types: octagonal ring gasket and elliptical gasket. According to their cross-sectional shape, they can be further divided into octagonal and elliptical structures. However, the two structures are different. The octagonal ring gasket matches the flange groove, mainly manifested as face-to-face contact. Although it cannot achieve a tight fit with the flange groove like the elliptical ring gasket, it can be reused and is very easy to process; The elliptical ring gasket is in line contact with the flange groove, making it have good sealing performance. However, the requirements for processing accuracy are very high, which naturally increases the related manufacturing costs. It is worth noting that elliptical ring gaskets cannot be reused.
There are also metal ring gasket, metal lens gasket, and metal winding gasket. The gasket itself can have strong high temperature resistance and high pressure resistance, making it very suitable for high-pressure flanges. The sealing of the gasket is also very durable and reliable, and can adapt to different load conditions. So, the development prospects are highly regarded by people!
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.
