PVC Coated Copper Tubes

-- Steady & Reliable Manufacturer --

Advanced Protection for Harsh Environments

PVC coated copper tubes are the ultimate solution for installations where the copper pipe is exposed to corrosive external elements. While copper is naturally corrosion-resistant, certain environments—such as underground burials, chemical plants, or coastal areas with high salt spray—can accelerate the degradation of bare copper. To combat this, we apply a high-grade, UV-stabilized Polyvinyl Chloride (PVC) jacket over the copper tube. This outer layer acts as a physical and chemical barrier, preventing direct contact between the copper and aggressive soils, concrete, or moisture. The coating is applied through a precision extrusion process, ensuring a consistent thickness and a tight bond that doesn't easily peel or crack, even during bending or installation in extreme temperatures. This product effectively combines the superior fluid-carrying capabilities of copper with the ruggedness of industrial plastics.

In addition to chemical protection, the PVC coating serves several functional purposes. It provides a level of thermal insulation, reducing heat loss in hot water lines and preventing condensation on cold water lines. It also acts as a vibration dampener, making it ideal for gas lines or industrial air systems where mechanical noise needs to be suppressed. We offer the PVC jacket in various colors, which serves as an easy identification system—for example, yellow for gas lines, blue for water, and white for HVAC applications. This color-coding is essential for safety and maintenance in large facilities. At Zhejiang Jingliang, our PVC coated tubing is manufactured to withstand the test of time, ensuring that even in the most demanding industrial or residential environments, the integrity of your piping system remains uncompromised. This proactive approach to protection significantly extends the service life of the system and reduces the need for costly retrofits.

Applications in Corrosive & Exposed Areas

PVC coated copper tubes are primarily used in three sectors: gas distribution, underground plumbing, and industrial fluid transport. For gas lines, the yellow-jacketed copper is the standard for both LPG and natural gas, providing protection against mechanical damage and soil acidity when buried. In domestic and commercial plumbing, blue or green coated tubes are used for water lines that pass through concrete slabs or masonry, where the alkaline nature of the concrete would otherwise corrode the bare copper. In industrial environments, these tubes are used in chemical processing plants to protect air and fluid lines from acid fumes and chemical splashes. They are also popular in marine environments, where the PVC layer protects against the corrosive effects of salt air. Furthermore, the insulation properties make them suitable for simple solar thermal installations and domestic hot water circuits where basic heat retention is required without the bulk of traditional foam insulation.

Key Advantages of PVC Jacketing

The most significant advantage is the extended lifespan of the piping system in aggressive environments. By isolating the copper from the external atmosphere, you virtually eliminate the risk of "pitting" corrosion and external oxidation. This makes it a "fit and forget" solution for underground installations. Another major benefit is the ease of installation; the smooth PVC surface makes it much easier to pull pipes through conduits or tight structural openings. The color-coding simplifies troubleshooting and ensures compliance with local building codes, which often mandate specific colors for gas and water lines. Additionally, the PVC layer provides a soft "cushion" that protects the copper from accidental scratches or dents during the construction phase. For the end-user, the reduced condensation on cold pipes prevents water damage to ceilings and walls, while the thermal barrier provides a minor but measurable improvement in energy efficiency.

Logistics, Customization, and Payment

We provide PVC coated copper in both pancake coils (for easy handling) and straight lengths. We can customize the coating thickness and color based on your specific project requirements or local national standards. For payment, we offer the standard T/T and L/C options, and we are capable of handling high-volume OEM orders where custom branding can be printed directly onto the PVC jacket. Shipping is handled with care to ensure the PVC surface remains un-scuffed; coils are often shrink-wrapped and palletized, while straight lengths are bundled in protective sleeves. We have a dedicated quality control team that tests the adhesion and thickness of the PVC coating for every production run, ensuring that the product you receive meets the exact technical data sheet specifications provided at the time of order.

  • Q: Can I use PVC coated copper for high-temperature solar applications?
  • A: The PVC coating is rated up to 95°C. For standard domestic solar systems, this is sufficient. However, for high-stagnation-temperature collectors, we recommend our specialized insulated pipe sets.
  • Q: Does the PVC coating contain lead?
  • A: We offer both standard and lead-free PVC coatings to comply with environmental regulations such as RoHS and REACH, depending on your market's requirements.
  • Q: How do I join PVC coated pipes?
  • A: You simply peel back the PVC coating by about 2-3 inches to expose the bare copper, perform your brazing or soldering, and then seal the joint area with specialized PVC tape or heat-shrink sleeves to maintain protection.
