Copper tube is one of the components that is needed in air conditioning and refrigerant system. The tube is used as a path for the refrigerant to flow between system components and to contain it from escaping to the atmosphere.
Sizing, installation layout and fittings must be done properly to ensure that the system runs efficiently. In the growth of air conditioning and refrigeration market the need for copper tube had increasing significantly.
There are basically two types of tube namely the hard-drawn and the soft type.
Hard Copper
This type of tubing is rigid, hard and stiff. It is not easily bent and should not be bent. Fittings are used to obtain the configuration needed for the installation. The length commonly available is 5.8meter
Soft Copper
The soft copper is flexible and comes in rolls of 15meter. The typical outer diameter ranges from 1/4 inch to 13⁄8 inch. Markings of ACR are done on the tubing to indicate that it is used for air conditioning and refrigeration purposes. During production, these parts are cleaned and dehydrated to remove the moisture from the tube. It is then filled with nitrogen gas before being capped.
Types of Copper Pipe Fitting:
A range of pipe fittings are made of copper. Some of the common pipe fittings commonly use in refrigeration system include:
- Copper elbow 45° / 90°
- Cooper Reducer,
- Cooper Reducer TEE
- Copper TEE,
- copper coupling,
- copper pipe
