During the installation and construction of
carbon steel pipes (cs pipe), it is usually necessary to connect and fix the steel pipes. So what are the three connection methods of carbon steel pipes? Next, the editor will briefly introduce it to you.
1) What are the three connection methods of carbon steel pipes?
1. Welding
Welding connection is a relatively common steel pipe connection method. Generally, the steel pipe interface and welding rod are heated, and then the weldments are connected and fixed together. This connection method has the advantages of firm welding, good sealing, good durability, low cost, and no need for frequent maintenance.
2. Thread connection
Threaded connection is also called threaded connection. Steel pipes have internal and external threads. By tightening the internal and external threads of two steel pipes, the steel pipe connection is fixed. The steel pipe threaded connection has the advantages of simple operation, convenient disassembly and assembly, and reliable connection.
3.
Flange connection
The flange connection is to fix the two flanges to the connection ports of the two steel pipes respectively, and then install flange pads and bolts to fix the pipe connection. The flange connection has the advantages of high strength, good sealing, and convenient disassembly.
2) What should be paid attention to when connecting carbon steel pipes?
1. When we connect
seamless carbon steel pipes, no matter which connection method is used, the steel pipes need to be processed in advance. For example, we want to check whether there are rust, burrs, and unevenness in the interface of a carbon steel pipe. The existence of these problems will affect the connection quality of the steel pipe, and the problem of leakage is prone to occur. Everyone should clean up the impurities on the surface of the steel pipe in advance, and the surface of the steel pipe should be clean, smooth and flat.
2. When connecting carbon steel pipes, the installation and construction requirements must be strictly followed, and the connection materials must meet the construction requirements. For example, when we use flanges to connect steel pipes, the specifications and sizes of flanges and bolts must meet the requirements. After the flange is fixed on the steel pipe, the flange gasket should be installed, and the gasket should be concentric with the steel pipe and so on. The flange bolts should be tightened, but the specified torque should not be exceeded.
