The present invention relates to a pipe connecting device for connecting a plurality of pipes. More specifically, the present invention relates to a pipe connecting device which connects each pipe with a relatively simple structure and can improve the reliability of a pipe connection portion. The pipe connecting device comprises a pipe having a protrusion on the connection end of the pipe; a first cylindrical connecting member having a spring mount portion to which a circular plate spring is mounted, a pipe through hole through which the pipe penetrates, and a screw groove inside; and a second connecting member including an O-ring mount portion in which an O-ring is mounted on a pipe connection part, having a screw thread on the outside, and having a penetrated part having the same diameter as the pipe. The pipe connecting device does not cause deformation of the pipe. Since the structure is relatively simple, a non-skilled worker can connect each pipe easily and the reliability of the pipe connection part can be improved. More specifically, in the case of a pipe comprising a thin plate made of stainless steel and copper and having a small difference between inner and outer diameters, deformation due to the pipe connection structure can be prevented, the speed and the flow rate of a fluid flowing along the pipe can be maintained. In addition, in order to connect the pipe, it is not necessary to secure a work space and each pipe can be easily connected without any additional tools in a field. |
