Annealed Copper Tubes PVC Coated are high-quality copper tubes manufactured through an annealing process and protected with an external Polyvinyl Chloride (PVC) coating. These tubes combine the excellent flexibility and thermal conductivity of annealed copper with the added protection of PVC, making them an ideal choice for HVAC systems, refrigeration units, LPG gas installations, and various industrial applications.
Annealing is a heat treatment process that softens the copper, improving its flexibility and making it easier to bend and install without cracking. This characteristic allows technicians and installers to route the tubing efficiently through confined spaces and around structural obstacles. The additional PVC coating acts as a protective barrier against moisture, chemicals, abrasion, and contact with construction materials such as cement and plaster.
Because of their superior performance and ease of installation, PVC coated annealed copper tubes are extensively used in split air conditioning systems, refrigeration equipment, concealed utility services, and approved propane gas applications. Their durability and corrosion resistance contribute to reduced maintenance requirements and extended service life.
Whether utilized in residential buildings, commercial facilities, or industrial projects, annealed PVC coated copper tubes continue to provide dependable performance and excellent long-term value across a wide range of applications worldwide.
Annealed PVC coated copper tubes are soft copper tubes that have undergone controlled heat treatment to improve flexibility and ductility. These tubes are then covered with a layer of Polyvinyl Chloride (PVC) to protect the copper surface from environmental damage and mechanical wear.
The annealing process reduces hardness and internal stresses within the copper, making the tubes easier to shape and install. The PVC coating enhances resistance to corrosion, moisture, and external impacts while improving the appearance of exposed piping.
These tubes are commonly supplied in coil form, allowing long continuous runs with fewer joints and connections.
These tubes are extensively used in split air conditioning systems to transport refrigerants efficiently between indoor and outdoor units.
Refrigeration applications utilize annealed copper tubing because of its flexibility and excellent heat transfer characteristics.
Approved LPG and propane systems may incorporate these tubes to provide protected and reliable fuel distribution.
These tubes are suitable for building service installations requiring flexibility, corrosion resistance, and mechanical protection.
One of the most important features of annealed copper tubes is their exceptional flexibility, which simplifies installation and reduces the need for multiple fittings.
The PVC coating provides superior protection against moisture, chemicals, abrasion, and external damage.
Copper's excellent thermal conductivity supports efficient performance in HVAC and refrigeration systems.
The tubes maintain smooth internal surfaces, ensuring efficient refrigerant, gas, or fluid flow.
Their lightweight construction makes transportation and handling easier on-site.
The protective coating also improves aesthetics and reduces maintenance requirements in exposed installations.
