State is the country of copper resource relative shortage, bauxite resource relative abundance, and in order to reduce cost, being using aluminum pipe on portions can
Capable, but since copper pipe differs about 400 DEG C with aluminum pipe fusing point, it often needs to use copper aluminium in the junction of copper pipe and aluminum pipe
Connector realizes that the pipeline between different tubing connects.Generally required in refrigeration piping section it is smooth as possible, without unexpected undergauge or expansion
The case where, therefore, existing copper-aluminium joint generally requires the internal diameter of joint structure equal or close with aluminum pipe internal diameter, copper-aluminium joint
Outer diameter and aluminum pipe outer diameter it is essentially identical.Existing copper-aluminium joint is using outer diameter same or similar copper pipe and aluminum pipe socket joint type knot
The connection of structure, copper and aluminium is by the way of hot extrusion, and in copper aluminium junction, tube wall is than relatively thin, and the bond strength of copper and aluminum pipe is not
Height is easy to be torn, and copper pipe is made to be separated with aluminum pipe section.
