Flange gasket Dg200 is a washer-like part used to seal the connection between two flanges, widely applied in the joints of various pipelines, valves, containers, pumps, and other equipment. Its primary function is to fill the microscopic gaps between the flange connection surfaces, preventing fluid or gas leaks.

Flange gasket Dg200 is made of various materials, including metallic gaskets, non-metallic gaskets, and semi-metallic gaskets. Metallic gaskets are typically made from stainless steel, copper, aluminum, brass, and other metals, offering high hardness and strength. They are suitable for environments with high pressure, high temperature, and strong corrosively. Non-metallic gaskets, on the other hand, are made from materials such as asbestos, rubber, polytetrafluoroethylene (PTFE), and flexible graphite, providing good sealing performance and corrosion resistance. They are suitable for low-pressure, low-temperature, and neutral environments. Semi-metallic gaskets are a compromise between metallic and non-metallic gaskets, often composed of a composite of metal and non-metal materials, offering good strength and sealing performance.

Apart from material, Flange gasket Dg200 comes in various shapes and structures, including flat gaskets, corrugated gaskets, lens gaskets, octagonal gaskets, etc. Different shapes and structures are suitable for different flange connection forms and sealing requirements.

The correct selection and installation of Flange gasket Dg200 are crucial for ensuring the sealing performance and safe operation of the system. When selecting flange gaskets, factors such as the flange connection type, nominal pressure, working temperature, and medium characteristics need to be considered. During installation, it is essential to ensure that the gasket is parallel to the flange surfaces to prevent damage or displacement of the gasket. Additionally, the gasket should be evenly distributed between the flange connection faces to avoid any gaps.
