The technology for laying AC copper pipes when installing air conditioning systems involves the following steps:
Copper pipes for conditioners are placed in a special box, and the drainage channel is placed at a slope, to drain condensate. Between the external and internal blocks create two highways of copper tubes. The gas line delivers the refrigerant in the form of gas (usually freon) from the compressor to the condenser and from the evaporator to the compressor, the second circuit of the conditioner copper tubes delivers the refrigerant in the form of liquid from the condenser to the evaporator. At the next stage, AC pipes and blocks are connected into a single system, the joints are checked for leaks.
Docking of conditioner pipes by soldering, preliminary cleaning and degreasing of pipes, applying a special hermetic paste, uniform heating of the joint with a torch, applying solder, cooling the joint in natural conditions and removing excess sealant.
In some cases, AC copper tubes are placed in an additional insulating channel. The use of additional insulation of copper tubes in cooling systems eliminates the risk of accumulation of condensate generated during the operation of air conditioners in critically large volumes. One of the elements of the insulation system is a special safety valve. This valve performs the function of protecting copper tubes in the temperature range from -150ºС to + 150ºС.
At AL Farid Wood and Metal Trading Company, you can buy copper tubes of any length and diameter from leading manufacturers at competitive copper pipe prices. Also customers can get comprehensive advice on their installation and maintenance in cooling systems.
For many years aluminium foil is in common use for cooking and packaging. However, there are still many rumors and guesses around its properties.
First, to tell the truth, we should admit that, as according to the laws of physics, food and bakery foil transfer their smallest particles to each other when contacting. However, this quantity is so miserable to put your health at any risk.
First of all, let’s clarify why bakery foil has dull and shiny sides. Such a difference is just a result of its manufacturing technology peculiarities.

Second, the foil paper has an Al2O3 oxide coating that protects food from oxidizing. Still, such goods as lemon and other alkaline and acidic food destroy this coating and, then, interact. The only truth here is that this can spoil the food taste.
