The octagonal pad is matched with the flange groove, mainly manifested as surface touch. Compared with the oval 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. The oval ring gasket has a linear contact with the flange groove, which provides good sealing performance. However, high processing accuracy is required, which increases the production cost. At the same time, the oval ring gasket cannot be reused.
Corrosion resistant low hardness metal ring gasket: using customized low-carbon metal materials, adjusting trace elements, and modifying ordinary heat treatment methods to ensure 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 process pipelines in many industries such as petrochemicals, chemical engineering, metallurgy, refining, gas, nuclear energy, and thermal power.
Made by machining metal blanks that have been cast and heat-treated. This type of gasket has a line or surface contact sealing surface, and has good rigidity and high strength. It is suitable for high-pressure steam, gas, solvents and other fluids, such as high-pressure vessels, high-pressure valves, ultra-high pressure reaction towers, etc. The commonly used metal ring plates are the R series, which are divided into oval and octagonal shapes according to their cross-sections. There are various specifications at home and abroad, but the scale of the same ring number in various specifications is basically the same and can be used universally. There are also enhanced RX and BX models. The R series metal ring gasket has a high operating pressure of 2500PSI (17MPa), while the BX type can be used for a pressure rating of 15000PSI (100MPa), and the lens shaped ring gasket can be used for a pressure rating of 300MPa and above.
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.
