Disclosed is a method for connecting pipes, capable of efficiently connecting a connection part between the pipes in which high airtightness and binding force are required by a simple method to pressurize the connection part through a hole with the diameter smaller than the connection part without a welding work or using a separate connection unit. In the method for connecting a first end unit to form one end of a first pipe and a second end unit to form one end of a second pipe, the first and second end units form the connection part while the second end unit is inserted into the first end unit. A gap between the first end unit and the second end unit is connected by being pressure welded in a pressure transformation process in order for at least one part of the circumference in the connection part to be inserted into the pipe. |
