Curves or tube bending in refrigeration and air conditioning systems

This operation is widely used, because the union of the components of the refrigeration systems is not always processed in linear stretches, in this way it is necessary to perform the folding of the pipes according to the path of the pipes, always promoting the interconnection of the components with the minimum quantity possible curves.
The "bending" of tubes is done through the use of bending machines which may be of the lever type as well as of the spring type.

The bending machines comply with the application for different pipe diameters and can not be used to bend another pipe smaller or larger than its nominal diameter. In addition to presenting a specific diameter for each tube, the bending curves present as one of their main characteristics the radius (r) of the curve that is desired to perform, for the most part this radius is fixed.
The degree of curvature of the tube can be observed by means of a
engraved on the side of the bender, curved guide, and can present from 0 ° to 90 ° or 0 ° to 180 °.
