Differences between XB350 and XB450
Thread Content
What is the difference between XB350 and XB450 in asbestos rubber sheets? Thank you.
XB35O: Material: It is made by pressing high-quality asbestos and rubber as the main raw materials. Use: Suitable as a sealing gasket material for flange connections in equipment pipelines handling media such as water, saturated steam, gas, ammonia, and alkaline solutions. Maximum operating temperature: 350°C. Operating pressure: 4.0 Mpa. XB450: Application range: Suitable as a sealing gasket material for equipment and pipeline flanges, as well as various contact connections, in systems where the medium is cold or hot water or steam, under conditions of a maximum temperature of 450°C and a pressure of 6 MPa.
In summary, there are two differences: 1. The manufacturing materials are different; 2. Their areas of use are different. The information on the 2nd floor is quite comprehensive. Generally, asbestos rubber gaskets are used only in medium-pressure applications; they are commonly employed with water and other dry gases. In many pressure pipelines, spiral gaskets or octagonal gaskets are used for medium- and high-pressure systems
