Description of the Related Art When a machine such as a synthetic resin molding die or a metal die casting die is provided with a cooling water circulation path (pipe) inside the molding apparatus, the inside of the cooling water pipe is stored. It is well known that oxidative corrosion occurs inside pipes when a small amount of water remaining in the air comes into contact with air.

止することができなかった。As means for preventing these oxidative corrosion,
A means to prevent oxygen from flowing through the pipe was installed by attaching a plug called a "sealing coupler" to the end of the pipe, but in this method, air was not introduced into the pipe after the plug was attached. Although it can be prevented from flowing in, it was not possible to prevent the occurrence of oxidative corrosion caused by oxygen contained in the water remaining in the pipe.
