Flange quartz tube is a special industrial component that combines the high temperature resistance of quartz tube and the convenience of flange connection. Quartz tube is widely used in various high temperature, high pressure and highly corrosive environments due to its excellent high temperature resistance, corrosion resistance and insulation performance. Flange, as a common connector, can easily connect multiple pipes or equipment with good sealing. It provides a more convenient and reliable solution for pipe connection in various high temperature, high pressure and highly corrosive environments.
