The present invention relates to a connection pipe for an expansion tank and a coupling method for the connection pipe for an expansion tank and, more specifically, to a connection pipe for an expansion tank and a coupling method for the connection pipe for an expansion tank, in which the connection pipe is mounted on an expansion tank by applying pressure thereto and the connection pipe is fixed to the expansion tank by pressure, simultaneously enabling sealing for preventing fluid leakage. The present invention comprises: an expansion tank having at least one receiving hole wherein the receiving hole includes a burring tap protruded inwards or outwards; a connection part made of a hollow cylindrical member, inserted into the receiving hole of the expansion tank so as to be fixed therein, and capable of connecting the expansion tank with an external device; and a sealing part formed between the connection part and the expansion tank so as to prevent fluid leakage to the outside of the expansion tank. |
