The metal octagonal ring gasket is a solid metal gasket made of metal material with a cross-sectional shape of octagonal or elliptical, which is in contact with the inner and outer sides (mainly the outer side) of the flange trapezoidal groove. The octagonal ring gasket, which is compressed to form a seal, is matched with the flange groove, mainly indicating a surface touch. Compared with the elliptical ring gasket, although it is not easy to achieve a tight fit with the flange groove, it can be reused, and because the cross-section is composed of straight lines, it is easy to process. There are actually many different classifications of such products, which can be divided into metal octagonal gaskets, octagonal metal ring gaskets, and metal octagonal gaskets according to their different application properties.
The metal octagonal ring gasket has good sealing performance, but requires high processing accuracy, which increases the production cost. The elliptical ring gasket cannot be reused together. Corrosion resistant low hardness metal ring gasket: made of customized low-carbon content metal material, adjusted for trace elements, with radial self tightening sealing effect. The modification of the general heat treatment method ensures the implementation of low hardness metal ring gaskets. The product is widely used in high-temperature and high-pressure equipment, as well as static sealing parts of technical pipelines in many professions such as petrochemicals, chemical engineering, metallurgy, refining, gas, nuclear energy, and thermal power.
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.
