The large loose disc internally threaded copper pipes and air conditioning tubes produced by our company have bright surface, compact structure, high-precision size and stable annealing performance, and are easy to produce and package, and are widely used in air conditioning and refrigeration, pipeline HVAC, mechanical power and rail transit and other market fields.
It 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.
High strength and good mechanical properties, different annealing processes can be customized according to the requirements of different customers to ensure that the copper tube can withstand different pressure and tensile force to meet different use environments; At the same time, the good mechanical properties ensure that the copper tube is not easy to be damaged during processing and use, and prolong the service life of the product;
Excellent thermal conductivity, large loose coil copper tube has excellent thermal conductivity, especially suitable for fields that need rapid heat dissipation, such as air conditioning, refrigeration, HVAC, etc. So as to effectively improve the heat dissipation efficiency of the system, reduce energy consumption, and improve the overall thermal conductivity and heat dissipation performance of air conditioners, fans, HVAC and other equipment;
Suitable for large-scale production, the production process characteristics of large loose coil copper pipes perfectly solve the problems of small weight of a single coil (generally 80~180kg for a single coil) and cumbersome handling in the traditional process.
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.
