Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, pressed connection, or solder.
Jun 13, 2017· Copper refrigerant lines play an essential role in air conditioning systems: They are responsible for carrying the refrigerant between the condensing unit and the evaporator coil. There are two copper lines that run between the condenser and the evaporator coil. The larger line is known as the suction line, return line, or vapor line. It carries cool gas, so it must be insulated with tubing.
Jun 29, 2021· Add Copper Tube to Fan. Coil the copper tubing and add it to the fan's protective grid.

When you silver solder you will need an oxy/ acyt. torch with a very small tip. i agree with Flukecej, no O/A till you're proficient, use a air/acetylene or a MAPP torch, the O/A can melt the Cu tube way fast and in a hurry if you aren't watching. Comment.
This tubing comes cleaned and capped to prevent moisture and dirt from contaminating the inside. It is also known as refrigeration and air conditioning tubing. Tubing has good corrosion resistance and excellent heat transfer qualities. It is seamless, which provides a smooth interior for unrestricted flow. It can be flared without splitting.. Note: Copper tube size is an accepted industry ...
systems, not closed central heating systems. Although failures of copper and brass fittings can occur in central heating systems, they are extremely rare as the dissolved oxygen content of the water is normally insufficient to cause corrosion. That is not to say that copper corrosion failures are common in domestic (drinking) water systems.
