た多くの欠点を有する。In piping lines such as gas pipes and water pipes, synthetic resin pipes and metal pipes are connected when branch pipes are branched out from the main pipe or when the piping line is extended. If the pressure of the transport fluid is increased in order to spread the fluid to the end of the piping line, troubles such as damage to the joint between the metal pipe and the synthetic resin pipe, resulting in leakage, often occur. In other words, various types of structures have been known for dissimilar pipe joints that connect synthetic resin pipes and metal pipes, but in general, the joints of dissimilar pipe joints between synthetic resin pipes and metal pipes are made of synthetic resin. It is inferior in strength and airtightness to joints of the same type of pipe fittings, etc., and requires time and effort to connect on-site, and there are problems with the long-term stability of joints of different types of pipe fittings. It has many drawbacks, such as:
