With the rapid development of the pipeline industry, there are more and more ways to connect pipelines. Do you know how many commonly used pipeline connection methods do you know? I will show you the common pipe connection methods.
1.Threaded connection
The threaded connection connects pipes and pipes, pipes, and valves through internal and external threads. This connection is mainly used for the connection of steel pipes, copper pipes, and high-pressure pipelines.

2.Welding connection
As the most traditional connection method, the welding connection is also the most commonly used connection method in daily life. Its main characteristics are that the interface is firm and durable, and the sealing degree of the interface is high. It does not require frequent maintenance. There are many commonly used welding methods.

3-Socket connection
In chemical pipelines, cast iron pipes used for water conveyance mostly adopt socket connections. The socket connection is suitable for cast iron pipes, ceramic pipes, plastic pipes, etc. It is mainly used in upper and lower water pipelines with low pressure.

4.Adhesive connection
The adhesive connection is to use adhesive as bonding filler to bond homogeneous pipes and pipe fittings together to play a sealing role. The adhesive connection has the advantages of simple construction and fast curing speed and is widely used in drainage

5. Flange connection
Flange connection is to fix two pipes, pipe fittings, or equipment on a flange plate respectively, then add a flange gasket between the two flange plates, and finally, tighten the two flange plates with bolts. It is a detachable joint that is tightly integrated.

6. Pipe connector
The pipe connector is a new type of pipe connection device. It breaks through the traditional connection concept. It uses stainless steel and rubber to make a component combination device to achieve the sealing and pressure bearing function. There is no need to do any treatment on the pipe end during construction, as long as the connector is sleeved. At the two pipe ends to be connected, tighten the side bolts, so that the clamping teeth bite the pipe end surface to a limit and fix, and the sealing sleeve is tightly attached to the pipe to achieve a tightly sealed and locked state.

7. Groove connection
Groove connection is to process an annular groove in the pipe joints and other parts. A sleeve types quick joint composed of clamp parts, rubber sealing rings, and fasteners, etc., when installing, cover the adjacent pipe ends with special-shaped rubber sealing rings After that, it is connected with a split type clamp piece, the inner edge of the clamp piece is positioned in the groove and fastened with fasteners to ensure the sealing performance of the pipeline. This connection method has the advantages of not damaging the steel pipe galvanized layer, quick construction, good sealing performance, and easy disassembly. It can be used in pipeline projects such as building water supply, fire water supply, and production water.

8. Card sleeve connection
A connection method in which the pipe is pressed against the pipe fitting with a lock nut and an open pressing ring. Features: The card sleeve-type pipe fittings have a short sealing surface, convenient and simple installation, and can be disassembled without special tools. Generally used in tap water and gas systems with specifications below 2632.
The above are some of the most common pipe connection methods. Which method is used to connect depends on the working conditions.
