The key of gas pipeline connection

The key to ensure the air tightness of gas pipeline connection is to choose suitable joints and correct connection methods. For gas pipeline connection, it is generally recommended to use special gas pipe joints. The following are some common types of gas pipeline connection joints:

flanged joint

Connect pipes with flanges and bolts. This joint is usually used in large pipelines and high-pressure systems to provide reliable sealing performance.

nipple

Sealing is achieved by connecting the threaded mating joint to the pipeline. Threaded joints are suitable for smaller pipelines and low-pressure systems.

Pressure joint

By using a compression sleeve and a washer, the pipe is connected to the joint and compressed with a nut to form a seal. Pressure joints are suitable for small and medium-sized pipelines and medium and low pressure systems.

Welded joint

Connect the pipes together by welding to provide a firm connection. This joint is suitable for pipes that need long-term use and high-strength connection.

Installation and maintenance procedures

No matter what kind of joint is used, high-quality joint and sealing material must be selected and connected in strict accordance with installation specifications. In addition, an appropriate sealant or gasket can be added at the pipe joint to improve the sealing performance. In order to ensure safety, it is recommended that professionals install and connect gas pipelines.
