The service life of this pipe is as short as 5 years and as long as about 20 years. This is because metal pipes are mainly used for conventional pipes and are easily affected by water quality, smoke damage, electrolytic corrosion and the like. Therefore, in recent years, piping using hard vinyl chloride has been used instead of the metal pipe.

ることを目的とする。However, when piping is performed using a synthetic resin material, the durability of the piping itself is extremely long. However, since a joint is used in a joint portion of the piping, this portion is exposed to ultraviolet rays and oxygen. However, there is a problem that the water leaks due to the peeling of the adhesive due to the water hammer phenomenon and the like.
Here, of course, the resin pipe to be joined is also joined by plastic welding, but there is a possibility that the material is changed by heating, and furthermore, the work is extremely troublesome, so the workability is poor. There is a problem. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of connecting a synthetic resin pipe with improved workability using a method similar to the conventional method, and a joint cover used therefor.
