Description

Pipe compression joining apparatus The present invention relates to a pipe compression coupling device that can stably, easily, and conveniently compress and combine two pipes without tightening the coupling part with a clamp. Generally, the technology of joining two pipes has become an essential element in various industrial fields, such as construction, plants, pipe systems, and fluid and gas transfer systems, requiring both efficiency and stability. Common methods for joining pipes include screw joining, flange joining, welding, the use of adhesive, or crimping. Among these, the compression joint method is a technique in which two pipes are inserted and connected, and then the joint is firmly compressed using a clamp. It is mainly used for pipe work for the movement of fluids or gases, and is preferred in various fields because it has the advantages of simple installation, fast work speed, and application without specialized skills, as it does not require welding. However, conventional pipe compression joining methods have limitations in that they can only be applied to relatively small-scale pipe joining, as the diameter of the pipe increases, requiring a large amount of force for the worker to insert the two pipes and tighten them with a clamp. In addition, as the length of the two tubes increases, it becomes difficult to match the straightness. If two pipes are joined without proper alignment, the joint may be damaged or a uniform clamping force may not be applied when tightening the joint with a clamp, resulting in poor sealing performance and leakage.
