How to prevent gas leakage in gas pipeline connections?

Common pipe connection methods:
Gas pipeline connection methods generally include wire connection, flange connection and socket connection. Among them, wire connection is the most common and the most prone to air leakage.

Reasons for gas pipe joint leakage:

Reasons for gas pipe joint leakage may include loose pipe joints, aging seals, poor pipe quality, etc. If joint leakage is not dealt with in time, it will pose a threat to people's lives and property.

Common types of gas pipe joints:

In the installation and use of gas pipelines, it is crucial to ensure that there are no air leaks. Choosing the right connector and the correct connection method are key steps in achieving this goal. Here are some common types of gas line fittings:
1. Flange type interface: This type of joint uses flanges and bolts to connect pipelines. Because of its excellent sealing performance, it is usually used in large pipelines and high-pressure systems.

2. Threaded interface: The threaded interface tightly connects the joint to the pipe through matching threads to achieve a sealing effect. Unlike flange-type interfaces, it is more suitable for applications in small pipelines and low-pressure systems.

3. Compression-type joint: This type of joint uses compression sleeves and washers to fix the pipe on the joint, and is compressed by nuts to achieve a sealing effect. It is mainly suitable for small and medium-sized pipelines and medium and low pressure systems (boiler tube).

4. Welded interface: The welded interface directly connects the pipes together through welding technology to form a strong and leak-proof connection. This kind of joint is usually used in pipeline systems that require long-term stable operation and high sealing.

No matter which joint is used, it is necessary to choose high-quality joints and sealing materials, and strictly follow safe operating procedures for installation. In addition, sealants or gaskets can be added appropriately at pipe connections to enhance their sealing performance.

Commonly used leakage prevention measures for gas pipeline joints:

1. Leak-proof wire connection: Before installing the pipeline, you can use high-temperature and corrosion-resistant sealing materials to ensure that the sealing links will not be damaged or aged. At the same time, when making wire connections, strengthen the strength to ensure fastening. .

2. Flange connection is leak-proof: Flange connection is suitable for pipe brackets, elbows, joints and other parts. This connection method requires the selection of high-quality flanges and sealing gaskets to ensure a tight and leak-free connection.

3. Socket-type connection is leak-proof: Socket-type connection is to insert a pipe into a section of pipe, and use sealing materials to ensure sealing. It is suitable for pressure maintenance, pressure reduction, etc., and needs to be installed in strict accordance with the installation requirements.

Routine maintenance of gas pipelines:
In addition to choosing appropriate pipe connection methods and taking leakage prevention measures, you also need to pay attention to the following points in daily use:
1. Ensure compliance with pipeline usage regulations and operating specifications.
2. Regularly check the pipe connections for leaks and looseness, and repair and tighten them in time.
3. Environmentally friendly pipelines must be installed and tested using professional equipment.
4. Pipeline inspection and repairs are best done by professionals.
5. It is forbidden to modify the pipelines at will, and strictly control the gas usage.

Summarize:

Gas pipe joint leakage accidents often bring great safety risks to our production and life. Choosing the appropriate gas pipeline connection method and taking leakage prevention measures are key. At the same time, we also need to pay attention to pipeline maintenance and safe use in daily use. Hope this article can be helpful to you.
