Plastic-Coated Copper Tube

Plastic-coated copper pipe is a composite pipe composed of seamless copper pipe covered with wear-resistant and corrosion-resistant polyethylene plastic. These pipes are widely used in a variety of plumbing applications, including indoor hot and cold water pipes, buried and walled pipes, and pipes used in corrosive environments. In addition, the copper pipe with plastic coating is also suitable for conveying gas or other gases.

Plastic-Coated Copper Tubes Certifications

The plastic covered copper pipe has passed the ISO9001, 14001, 45001 system certification, as well as the American standard ASTM B 280, the Japanese standard JIS H 3300, the Australian standard AS 1571 and the European Union PED 4.3 and other product certifications.

Plastic-Coated Copper Tubes Performance Advantages

Corrosion resistance: Plastic-coated copper pipes can resist the erosion of chemicals and corrosive liquids and prolong the service life of pipelines;
Anti-wear: The overlying polyethylene layer increases the wear resistance of the pipe and reduces the damage caused by friction.
Good thermal insulation performance: The special concave groove design helps to intercept air to form an insulation layer, effectively prevent condensation, and is suitable for cold and hot water pipelines.

Application Fields

Insulated copper tubes are widely used in the air conditioning and refrigeration industry due to their excellent thermal conductivity and durability. These insulation copper tubes are critical components of air conditioning and refrigeration systems, as they help to transport refrigerant fluids between the different components of the system.

One of the main advantages of copper pipe insulation in air conditioning and refrigeration systems is their ability to withstand high pressure and extreme temperatures. These tubes are often subjected to significant stress and pressure, so their durability is essential for maintaining system performance and preventing leaks or other problems.

AC copper pipe insulation are also highly efficient in transferring heat. In air conditioning and refrigeration systems, heat transfer is a critical process that affects the overall efficiency of the system. Copper is an excellent conductor of heat, so insulated copper tubes help to ensure that the refrigerant fluid can efficiently absorb and release heat as it flows through the system.

Another important benefit of using insulated copper pipe air conditioning is their resistance to corrosion. Copper is highly resistant to corrosion, making it an ideal choice for use in environments where exposure to moisture or other corrosive agents is a concern. This resistance to corrosion helps to prolong the lifespan of the tubes and ensure that they maintain their performance over time.

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.
