Advantage:
Good mechanical properties
Because the steel bundy tube is made of high quality low carbon steel, it is easy to bend, easy to weld and easy to process in various shapes.
High strength
The steel bundy tube is welded along the 360° joint surface of the pipe wall to ensure that the Bondi pipe has the characteristics of high bursting strength and high anti-vibration fatigue limit, which can effectively prevent damage and leakage;
Application:
Precise Welded Single Wall Steel Bundy Tube is also important part of refrigeration system ,mainly used in refrigerator, freezer ,condenser, evaporator etc.
The steel 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.
First, the steel bundy tube can greatly reduce the cost of the refrigerator condensing tube;
secondly, the strength of the steel bundy tube is much ahead of the copper tube, which can effectively reduce the deformation of the refrigerator condenser product during transportation and use, and improve the service life of the refrigerator.
