Connection method of round tube and square tube

Connection method of carbon steel round tube and square tube:

1. Flange connection
Flange connection is a common way to connect round tubes and square tubes. It is usually used for the connection of large buildings or mechanical equipment and has high load-bearing capacity and strength. Flange connection requires cutting matching flange holes at the pipe opening, and then connecting the two pipes together through bolts and nuts. Flange connection is suitable for use when round pipes and square pipes are used at the same time, and can meet the connection needs of different angles and directions.

2. Threaded connection
Threaded connections are another common connection method. For the connection of square tubes and round tubes, threads can be provided on their interfaces, and then they can be connected through threaded connectors. The threaded connection method has the advantages of easy disassembly and reliable connection, and is suitable for occasions that require frequent disassembly and adjustment.

3. Pin connection
Pin connection is a simple and fast way to connect round and square tubes. It is usually used for connections in furniture, shelves, etc. The latch connection requires drilling a small hole at the end of the round tube and the square tube, and then connecting the round tube and the square tube together through the latch. This connection method does not require welding and bolts, so the connection speed is very fast, and it is more flexible and convenient, and can be disassembled and assembled multiple times.

4. Welding connection
Welding connection is a common way to connect round tubes and square tubes. It is usually suitable for connections in construction, mechanical equipment and other fields. Welding connection requires welding the ends of round pipes and square pipes to connect them together. This connection method does not require bolts and pins, and can provide stronger fixing force and load-bearing capacity. But welded connections require additional equipment and skills and cannot be disassembled multiple times.

5. Clamp connection
Clamp connection is a common way to connect round tubes and square tubes. It is usually suitable for connections in light construction, decoration and other fields. Clamp connections require a clamp to be placed on the pipe and then bolted together. This connection method is fast and difficult, and can be disassembled multiple times, but its load-bearing capacity is weaker than flange connections and welded connections. At the same time, due to the presence of clamps, there will be some breakpoints on the surface of the pipe, which affects the appearance.

To sum up, round tubes and square tubes can be connected using a variety of connection methods. Choose the appropriate connection method based on the usage scenario and actual needs, and pay attention to safety and fixation effects when connecting.
