Problems solved by technology
[0002] In actual production activities, there are many ways to connect pipes, among which the most widely used ones include welding type and compression type. The so-called welding type is to insert the pipe into the socket of the pipe joint and weld the joint part. , using this method requires a certain welding process, which has high requirements for workers and equipment, and the high temperature generated during welding will change the material properties of the heating part, thereby affecting the strength of the joint
[0003] Compared with welding, the clamping type is to set a ring of ribs on the pipe joint, and place a sealing gasket in the groove inside the rib. When the pipe is inserted into the socket of the joint, special tools are used to squeeze the socket so that It deforms and bites on the pipe; at the same time, the convex ribs are also deformed, compressing the gasket to make it fit closely with the outer wall of the pipe, so as to achieve the purpose of fastening and sealing, but this tool is expensive and complicated to operate, and needs to be adjusted before use Operators are trained, so it is not convenient for fast and efficient installation. Most importantly, it is easy to cause extrusion failure due to improper operation in this way, which affects the connection effect between pipes and seriously affects production efficiency.
