Abstract
The invention provides a Cu-Al pipe joint. The Cu-Al pipe joint is characterized in that: a stainless steel pipe of which the melting point is between that of a copper pipe and that of an aluminum pipe is selected; the copper pipe is welded at one end of the stainless steel pipe; and the aluminum pipe is welded at the other end of the stainless steel pipe. Therefore, the Cu-Al pipe joint is manufactured. Through the Cu-Al pipe joint, a plurality of problems caused by directly welding copper and aluminum are solved, and the requirements on the air tightness and the mechanical strength of the joint in the environment with low temperature and high humidity can be effectively met.
Description
One, technical field:
A kind of copper-aluminium tube joint belongs to the machine industry field.
Two, background technique:
The present copper-aluminium tube joint that uses generally is that copper pipe and aluminum pipe directly weld, because the potential difference of copper aluminium does not wait, so form electrochemical corrosion easily, two kinds of metal easy deformation of copper and aluminium are out of shape problems such as the easy leakage in joint, back.
Summary of the invention
The present invention provides a kind of copper-aluminium tube joint.
It is characterized in that a kind of a kind of metal between copper aluminium material matter fusing point of joint selection, like stainless steel.At one of which end welding aluminum pipe; The other end welding copper pipe; Its remarkable advantage is the problems that can overcome copper and the direct welding of aluminium; Can guarantee the airtight requirement and the mechanical strength of joint again, through copper-aluminium tube joint reliable welding quality under the environment of low temperature and high relative humidity of this copper-aluminium transition welding production of experimental verification, usability is stable.
Description of drawings
Figure is the copper-aluminium tube joint structural drawing
Aluminum pipe 1, stainless steel 2, copper pipe 3 among the figure
Three, embodiment
With Stainless Steel Tube one end and Al pipe butt welding and copper-aluminium tube joint is formed in the other end and copper pipe welding.This copper-aluminium tube joint can be widely used in the refrigeration system, and aluminum pipe replaces in the pipeline of copper pipe, thereby can save a large amount of copper materials, the good product of benefiting the nation and the people.
Claims (1)
1. copper-aluminium tube joint is welded to form by copper pipe and aluminum pipe and Stainless Steel Tube, and it is characterized by Stainless Steel Tube one end is copper pipe, and the other end is an aluminum pipe, adopts socket gas welding mode between the tube and tube.
