Bundy Tube Double Wall GoodCorrosion Resistance Copper Coated For Refrigerator Part 3.18 mm * 0.7 mm
Describtion
The Double wall Bundy that It is a high-precision special pipe produced by a unique copper rolling and copper brazing technology. It is plated with a lower melting point than the steel strip. The steel strip of solder (usually copper) is cold-formed into a double-rolled coiled tube through a forming machine, and then welded by a special heating device to form a double-layer coil welded pipe.

Application:
Double wall Bundy Tube is also important part of refrigeration system ,mainly used in refrigerator, freezer ,condenser, evaporator etc.
The Double wall Bundy Tube has been widely used in the refrigerator for more than 20 years. From the practical application, the steel bundy tube is successful in the refrigerator and the quality is reliable.
Advantage:
High resistance to vibration cracking and high pressure resistance
Double wall bundy tube has 2-3 times higher vibration fatigue resistance than copper or aluminum alloy tubes,which can effectively reduce the deformation of the refrigerator condenser product during transportation and use, and improve the service life of the refrigerator.
The price is lower than the copper tube
The Double wall Bundy Tube can greatly reduce the cost of the refrigerator,condenser, evaporators, refrigeration, chiller, heaters, freezer.
Precise geometric dimensions
The Double wall bundy tube is made of high-precision cold-rolled high-quality low-carbon steel strip. The exquisite rolling technology guarantees the outer diameter of the pipe, the precision of the wall thickness and good concentricity.
