What are the common pipe fittings and pipe connection methods?

Common pipe fittings and pipe (welded pipe) connection methods include the following:

1. Threaded connection
This is a common connection method in which internal and external threads on pipes and fittings are screwed together to create a tight connection. It is simple and easy to operate and suitable for low pressure and small diameter piping systems.

2. Welding connection

Pipes and fittings are welded together to create a permanent connection. Common welding connection methods include butt welding, fillet welding and socket welding. Welded connections are commonly used in piping systems with high pressures and temperatures.

3. Pressure connection
This is a common connection method that uses special pressure tools to compress sleeves or sleeves on pipes and fittings to form a sealed connection. Common pressure connection methods include ferrule connection, pressure sleeve connection and link connection. Pressure connections are suitable for piping systems made of many different materials.

4. Tension connection
Connections are made by clamping pipes and fittings together using bolts and nuts. This connection method is suitable for large pipelines and high-pressure pipeline systems.

5. Flange connection
Pipes and fittings are held together by pipe flanges and flange gaskets. Flange connections can be divided into flat welding flanges and butt welding flanges, which are usually used in large and high-pressure pipeline systems.

6. Clamp connection
Use clamps to clamp pipes and fittings together to create a connection. This type of connection is suitable for smaller diameter pipe systems such as water pipes and irrigation systems.

7. Quick connection
Quickly connect pipes and fittings to create a connection using quick connectors or quick connectors. This connection method is suitable for occasions that require frequent disassembly and replacement, such as liquid transmission and gas transmission.

The above are common ways of connecting pipe fittings and pipes. Choosing the appropriate connection method should be determined based on the specific pipeline system requirements and application scenarios. Before proceeding with installation, be sure to refer to relevant design and specification requirements and follow the installation guidelines provided by the manufacturer.
