PVC sheathed copper tube is a type of copper tube with an outer layer wrapped in PVC (polyvinyl chloride) plastic sheath. Copper tube is a high-purity copper tube with excellent conductivity and corrosion resistance. The PVC sheath provides additional protection and enhances the abrasion resistance, acid and alkali resistance and aging resistance of the copper pipe.

　　PVC sheathed copper tubeMain advantages:

1. Enhanced corrosion resistance

Copper pipes themselves have good corrosion resistance, but in harsh environments such as humid and high salt content, long-term exposure may lead to oxidation and corrosion. PVC sheath can effectively isolate corrosive substances from the outside, such as moisture, acidic or alkaline substances, significantly improving the corrosion resistance of copper pipes.

2. Good mechanical protection

The PVC outer sheath can provide certain mechanical strength protection for the copper tube, avoiding damage to the copper tube caused by external collision or friction. Especially in places with harsh construction environments, PVC sheaths can effectively prevent problems such as pipe breakage, flattening, or scratching.

3. Excellent electrical insulation

PVC has excellent electrical insulation properties, which enables copper pipes to better prevent current leakage and ensure safety in some electrical engineering applications. This is particularly important in places that require high insulation requirements, such as power facilities, communication equipment, etc.

4. Temperature resistance performance

Has good temperature resistance performance. Copper pipes themselves can withstand high temperatures, while PVC sheaths can typically work stably within the range of -15 ℃ to+60 ℃, meeting the needs of most common industrial and building environments.

5. Economy

Although the price is slightly higher compared to pure copper pipes, their corrosion resistance, wear resistance, and extended service life make the overall cost more economical, especially in some long-term use and harsh environmental conditions.

Application areas of PVC sheathed copper pipes:

1. Electrical and Electronic Industry

In electrical engineering, it is commonly used in fields such as power transmission and equipment wiring. Its excellent conductivity and insulation make it a common connecting component in power cables, electronic devices, and communication systems. Especially in some electrical equipment that requires protective pipes, PVC sheaths can effectively protect wires and cables from external environmental factors.

2. HVAC industry (HVAC)

Widely used in HVAC systems. It is used as a refrigerant pipeline, condensate discharge pipeline, etc., with good thermal conductivity, which can improve the thermal efficiency of air conditioning and refrigeration equipment. Meanwhile, the protective layer provided by the PVC sheath effectively prevents damage to the pipeline in high or low temperature environments.

3. Construction Engineering

In construction engineering, it is also widely used, especially in water and gas supply systems such as pipes and gas pipelines. PVC sheath can effectively prevent the invasion of external corrosive substances and ensure the long-term stable use of pipelines.

4. Chemical and pharmaceutical industries

In the chemical and pharmaceutical industries, it is used for fluid transportation and pharmaceutical equipment. Due to its corrosion resistance and high temperature resistance, it is suitable for transporting acidic and alkaline substances or some special chemical drugs. In addition, due to the smooth surface inside its pipeline, it reduces material adhesion and also helps improve production efficiency and equipment cleanliness.
