Connecting method of copper pipe

Abstract

A copper pipe joining method is provided to securely connect a copper pipe to a connector without welding because the overlapped part between the connector and the copper pipe is pressed by a presser, and gas tightness and water tightness between the copper pipe and the connector are maintained by using adhesive to bonding the overlapped parts after the coppers pipes are inserted into two sides of the connector. The connecting method comprises the steps of: coating metal-used adhesive on contact parts of the hollow connector made by a copper material and the copper pipes inserted into two sides of an inner diameter of the connector; inserting the copper pipes into inner sides of two end portions of the connector, in order to bond the copper pipes at the two sides on the connector; and using a presser to press the connection parts of the connector, in which the copper pipes are inserted, in order to form overlapped connector pressing parts and copper pipe pressing parts, wherein the overlapped connector pressing parts and copper pipe pressing parts are arranged outside the end portions of the copper pipes, so as to prevent the end portions of the copper pipes from separating from the connector.

Description

technical field [0001] The present invention relates to a copper pipe connection, and more particularly to a copper pipe connection method in which copper pipes are inserted into both sides of a connector, and the overlapped parts thereof are bonded with an adhesive to maintain air. Airtightness and watertightness, and crimping with a crimping machine so that the overlapping part between the connector and the copper tube is inserted in a concentric direction, and the crimping part is used to prevent the copper tube from detaching from the connector, so that it is different from the previous Different, copper pipes can be firmly connected even without welding. Background technique [0002] The traditional way of connecting copper pipes is to join them by welding. That is, the copper pipes are connected by melting the copper pipe connection portion and the base material with high-temperature welding sparks of oxygen, acetylene, and liquefied petroleum gas (LPG).

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, the copper pipe connection method using the welding method has the following defects: since the copper pipe is melted by high temperature, the crystallization of the welded part is different from that of the other part that is not melted after welding, resulting in the strength of the copper pipe. Weakened, especially when copper is oxidized when it is melted, the molten part produced during welding is rapidly oxidized over time, causing severe corrosion and shortening the life

[0004] In addition, the color of the molten part changes due to high temperature and affects the appearance, which becomes a disadvantage that reduces product quality

[0005] In addition, because of the use of explosive oxygen, acetylene, and liquefied petroleum gas, the work is highly dangerous, and if an explosion accident occurs due to the gas, it will cause a large-scale property damage accident, so skilled operators are required

Not only that, many operators were burned by high-temperature welding sparks during welding operations

[0006] In addition, in this welding method, since the devices required for welding, that is, the gas tank and the hoses connected to the gas tank, etc. are heavy devices, the movement of these devices is not only cumbersome when moving the welding site, but also takes a lot of time

[0007] Most importantly, welding sparks will splash on combustibles during operation, causing large-scale fire accidents such as the recent logistics warehouse fire, which has become a serious problem that repeatedly suffers losses of precious lives and property
