Overview

The sealing flange is an important connection device used in the piping system. Its main function is to ensure the normal operation of the piping system by providing a reliable seal. Sealing flanges are widely used in petroleum, chemical, electric power, metallurgy and other industrial fields, and are an indispensable part of the pipeline system.

Basic structure

The sealing flange is mainly composed of flange, sealing gasket, bolt and other connecting accessories. The flange is the main part of the flange, and its size, pressure and material grade are selected and customized according to the application requirements. The sealing gasket is located between the two flanges, and the pipeline is sealed by the tightening force of the bolt.

Main Types

According to different usage scenarios and parameters, there are many types of sealing flanges, such:

1. Flat welding flange: suitable for medium and low pressure pipeline system, convenient production and low cost.

2. Welding flange: suitable for high pressure, high temperature piping system, superior sealing performance.

3. Sliding sleeve flange: suitable for large-diameter pipes, easy installation and good sealing effect.

4. Threaded flange: through threaded connection, suitable for smaller diameter pipeline system.

Working principle

The working principle of the sealing flange is mainly through the tightening force of the bolt, so that the flange and the pipeline are closely integrated, and the sealing gasket plays a sealing role. When the piping system is under pressure, the flanges and gaskets will be deformed to ensure the tightness and tightness of the connection.

Application Areas

Sealing flange is widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical, food and other industrial fields. In the petroleum and chemical industry, it is mainly used to connect various equipment and pipelines to ensure the continuity and safety of the production process. In the power field, it is mainly used to connect boilers, generators and other equipment. In the field of metallurgy, it is mainly used to connect various smelting equipment and pipelines.
