Description of the purpose of the pressure vessel flange

Pressure vessel flange is a connection device installed on a pressure vessel to connect pressure vessels with pipelines, valves, equipment and other components. It plays the role of bearing, sealing and connecting, and is an important part of the safe and stable operation of pressure vessels.

Pressure vessel flanges typically include components such as flanges, gaskets, and bolts. The flange is the main part of the flange, and there are two types: fixed and removable. Gaskets are usually made of metallic or non-metallic materials and are used to fill the gaps between the flanges to achieve a seal. Bolts are used to hold the flanges together to ensure the firmness of the connection.

The pressure vessel flange has the following characteristics:

High strength: Pressure vessel flanges are usually able to withstand high pressures, so they need to have high strength and stiffness.

Strict tightness requirements: The tightness requirements of the pressure vessel flange are high to ensure that the pressure vessel does not leak.

Corrosion resistance: Pressure vessel flanges are usually resistant to the corrosion of the medium and therefore need to be manufactured with corrosion-resistant materials.

Suitable for all kinds of pressure vessels: Pressure vessel flanges can be applied to pressure vessels of different materials, structures and sizes to meet different process needs.

The selection of pressure vessel flange needs to be considered according to the specifications of the pressure vessel, the nature of the medium, working conditions and other factors, and the common standards are international standards (such as ASME standards, DIN standards, etc.) and domestic standards (such as GB standards). When selecting and installing pressure vessel flanges, strict calculations and operations need to be carried out according to the actual situation to ensure safe operation.
