Capillary Copper Tube

Capillary copper tube is a kind of copper tube with very thin inner diameter and outer diameter, which is widely used in household refrigerators, electric freezers, high-precision instruments, electronic equipment meters, etc.; The material is usually made of high-quality copper such as TP2 and TU1, which has excellent thermal conductivity and corrosion resistance. The application scenarios of copper capillary tube include:

(1) refrigeration system: capillary copper tubes are widely used in small freon refrigeration devices below 10KW, which can meet different working conditions and refrigeration capacity requirements by changing the length and diameter of the pipe;

(2) Gas transportation: suitable for cold water engineering and environmental protection engineering;

(3) Daily life: In the building water supply system, capillary copper pipes are widely used because of their good thermal conductivity and high low temperature strength.

What is Copper Tube used for?


Copper tube is a type of pipe made from copper that is used in a wide range of applications. Copper tubing is known for its excellent thermal conductivity, corrosion resistance, and durability, which make it a popular choice for a variety of industries.
Some common uses of copper tube include:

Plumbing
Copper is used for plumbing tubes principally because of its corrosion resistance, machinability and high level of heat transfer. Copper tubing is often used in residential and commercial plumbing systems for carrying hot and cold water, as well as gas lines.

HVAC systems
Inner grooved copper tube and other kind of copper tubing are commonly used in air conditioning and refrigeration systems for its superior heat transfer properties.

Electrical wiring
Copper tubing is sometimes used in electrical wiring for its excellent conductivity properties.

Industrial applications
Copper pipe for sale is applied to a variety of industrial applications, such as in the production of heat exchangers, boilers, and other equipment that requires a high level of thermal conductivity and corrosion resistance.

Transportation
Copper Tube applications for copper in the transportation industry are automotive and truck radiators, air-conditioning systems and hydraulic lines.

What is the Difference Between Copper Pipe and Copper Tubing


Copper pipe is typically used for plumbing and water distribution systems. It has a thicker wall and is available in various lengths and diameters. Copper pipes are usually sold in straight lengths and may have threaded ends or be connected using soldering or compression fittings.

Copper tube wholesale is often used for refrigerant lines in HVAC systems. Many types of copper tube have a thinner wall and is available in longer lengths than copper pipe. Copper tubing is commonly sold in coils, which makes it easier to handle and bend without the need for additional fittings.

Overall, copper pipe and copper tubing are both made of copper and can be used for similar applications, but their differences in wall thickness, length, and availability of fittings make them better suited for specific purposes.
