Copper pipes are one of the components required for air conditioning and refrigeration systems. This tube serves as a path for refrigerant to flow between system components and prevent it from escaping into the atmosphere. Dimensions, mounting layout, and fittings must be done correctly to ensure the system operates efficiently.

During installation, it is critical to keep moisture, dirt, and other contaminants out of the system. These foreign objects can affect the performance of the system and may even cause damage to certain components.

During the production of copper pipes, the inside of the pipe has been cleaned and dried, and then both ends are sealed to ensure that it remains intact. You have to check to make sure the refrigerant you will be using will not react with the copper. Ammonia refrigerant reacts with copper and should not be used. Instead, stainless steel tube types must be used.

There are basically two types of tubes, hard-draw tubes, and hoses.

This type of tubing is rigid, rigid, and rigid. It doesn't bend easily, nor should it. Accessories are used to obtain the configuration required for installation. Typically available lengths are 10 or 20 feet. Each type is available in three standard weights with different wall thicknesses. Type K has the thickest wall, followed by types L and M. If you need a higher pressure tube, you should use a thicker tube to make sure it can handle the pressure of the refrigerant. L-shaped OD usually starts at 3/8", then 1/2", 5/8", 3/4", 7/8", 11⁄8", 13⁄8", 15⁄8", 21⁄8" and 25⁄8".

Soft copper is flexible and can be rolled into 25' or 50'. Typical outside diameters range from 1/8" to 13⁄8". The marking of the ACR is done on the tubing to indicate that it is used for air conditioning and refrigeration purposes. During production, these parts are washed and dehydrated to remove moisture from the tubes. It was then filled with nitrogen before capping.

To prevent the refrigerant from absorbing unnecessary heat from the environment, copper pipe insulation is used between the evaporator and the compressor on the low-pressure side of the system. So you will be able to see the insulation wrapped around the copper pipe for this purpose. This is also to prevent condensation on the tubes.

When cutting the tube to the desired length, make sure to use the proper tool, such as a tube cutter. Burrs created inside the cut tube must be removed from the tube as these contaminants can affect the flow of the tube. refrigerant and affect the performance of the system.

When bending is required, please note that only soft copper types can be bent. Use a suitable elbow spring to prevent squashing or kinking.

When soldering or brazing is required, make sure you are trained and strictly follow the manufacturer's instructions.

Wear safety goggles when your actions cause particles to be released into the air.

When you do the annealing process that heats the tube and lets it cool slowly, make sure to use the burning flame 1 foot away at a time instead of concentrating the heat in one spot.

Make sure the workplace is well ventilated, especially if your work produces fumes. Do not breathe in excess gas and adhesive.
