The use of steel tubes is becoming more and more widespread with the development of the industrial and construction sectors. In some cases, it is necessary to connect two steel pipes together to form a whole. So, how to connect two steel pipes? The following methods for reference:

First, welding connection

The welding method is to butt the ends of two steel pipes, heat them to a certain temperature, and use welding wire to fix them together. This type of connection is usually applicable to the high structural requirements, the connection point to withstand the situation of strong force. The advantage of a welded connection is that it is a reliable and solid connection, but it also requires the fulfillment of certain conditions and operating skills. When welding, you need to pay attention to the protection of eyes, respiratory tract and the surrounding environment.

Second, threaded connection

Through the end of the steel pipe manufacturing thread, and then use the threaded parts of the two steel pipe threaded connection together. This connection is simple and easy, high reliability, easy to disassemble, but the need to create threads at the end, which is difficult for some large steel pipe connection. It should be noted that the corresponding threaded parts and thread specifications should be selected.

Third, sleeve connection

Sleeve connection is through a sleeve will be two steel pipe sets together, and then the sleeve and steel pipe together fixed, commonly used in larger steel pipe connection. This type of connection is relatively simple, the bearing capacity of the joint is high, but you need to choose the appropriate sleeve and fixing method to ensure that the connection is firm and reliable.

Four, ferrule connection

The ferrule connection is to first put a steel pipe into a ferrule with a clamping core and clamping ring, and then insert another steel pipe and use screws or pins to fix it. This connection can meet some special structural requirements, but need to pay attention to the selection of suitable ferrules and clamping methods to ensure a strong and reliable connection.

In short, the choice of which connection needs to be decided according to the specific circumstances. In the connection, you need to choose the appropriate tools and materials according to the connection method, and take appropriate safety measures.
