Insulated Copper Pipe Sets

-- Steady & Reliable Manufacturer --

The Efficient Solution for Modern HVACR

Insulated copper pipe sets, often referred to as "pre-insulated line sets," have become the standard for modern air conditioning and heat pump installations. The efficiency of a cooling or heating system is only as good as its thermal management, and uninsulated or poorly insulated refrigerant lines are a major source of energy waste and system performance degradation. Our insulated pipe sets feature high-purity C12200 copper tubes encased in a high-performance, closed-cell polyethylene (PE) or elastomeric foam. This insulation is not just a cover; it is a precision-engineered thermal barrier that minimizes heat gain/loss and prevents the formation of condensation, which can lead to mold growth and structural damage in residential and commercial buildings. By integrating the insulation and copper at the factory level, we provide a consistent, high-quality product that saves installers hours of manual labor on the job site.

At Zhejiang Jingliang, we focus on the "Twin-Tube" system, which includes both the liquid and suction lines pre-insulated and joined together. This design facilitates a much faster and cleaner installation, especially for split-system air conditioners and VRF units. The outer layer of our insulation is typically embossed with a UV-resistant film, protecting the foam from degradation when exposed to sunlight on rooftop or outdoor wall installations. We pay close attention to the "Fire Rating" of our insulation materials, ensuring they meet international safety standards such as Class 1 or Class B1. This is critical for meeting building codes in the US, Europe, and Australia. Whether you are a large-scale distributor or an HVAC contractor, our insulated pipe sets provide a professional, energy-efficient, and safety-compliant solution that enhances the reliability and aesthetics of any climate control installation.

Applications in Climate Control Systems

The primary application for insulated copper pipe sets is in the installation of residential and commercial "mini-split" air conditioners. These systems require a connection between the outdoor condenser and the indoor evaporator; our line sets provide this link with minimal energy loss. They are also used extensively in Air-to-Water and Air-to-Air heat pumps, which are a cornerstone of the global transition to renewable heating. In commercial settings, these sets are used for VRF/VRV systems, where multiple pipes are bundled together in ceiling voids. Because of the high-quality insulation, they are perfect for cold-room and refrigeration applications where maintaining a specific temperature delta is critical. They are also increasingly used in solar thermal systems to transport heated fluids from rooftop collectors to basement storage tanks. The versatility and ease of use make them the go-to choice for HVAC contractors working on both new constructions and retrofitting older buildings with modern energy-efficient systems.

Advantages of Factory Pre-Insulation

The most immediate advantage is the massive reduction in installation time. Manual insulation of copper pipes on-site is tedious, prone to gaps, and often results in an unprofessional finish. Our factory-applied insulation is perfectly concentric and continuous, ensuring there are no thermal bridges or air gaps. The closed-cell structure of the foam provides a built-in vapor barrier, which is essential for preventing condensation that can drip and damage ceilings. Another key benefit is the durability; the UV-resistant outer skin protects the insulation from the "birds-pecking" and sun-rotting common with standard black foam tubes. For the wholesaler, these pipe sets offer a high-value, high-margin product that is easy to stock and sell as a complete "installation kit." For the homeowner, the result is a quieter, more efficient air conditioner that looks sleek and professional on the exterior of the house. Most importantly, our insulation is lead-free and non-toxic, ensuring indoor air quality is maintained in residential environments.

Packaging, Payment, and Shipping

We pack our insulated pipe sets in reinforced, high-strength cardboard boxes to ensure they are not crushed or damaged during shipping. Each box is labeled with the length, tube diameters, and insulation thickness. We offer custom branding (Private Labeling) for large distributors, including custom box designs and printing on the insulation itself. Payment terms are typically 30% T/T deposit and 70% before shipment or against the B/L. For established partners, we can offer more flexible arrangements. We ship these globally, optimizing container loading by nesting smaller coils inside larger ones where possible. Our location near major ports like Shanghai and Ningbo allows us to maintain consistent shipping schedules. Every batch is tested for both copper quality and insulation fire-rating to ensure 100% compliance with the destination country's regulations.

  • Q: What is the benefit of the "embossed" film on the insulation?
  • A: The embossing provides extra mechanical strength and a higher degree of UV resistance compared to smooth foam. It also makes the pipe easier to pull through wall holes without tearing the insulation.
  • Q: Do you offer the pipe sets with flared ends and nuts?
  • A: Yes, we can provide "ready-to-install" kits that come pre-flared with high-quality brass nuts, further reducing installation time for technicians.
  • Q: Is your insulation fire-rated?
  • A: Yes, we provide various grades of insulation that meet B1 (China), M1 (Europe), and UL (USA) fire safety standards. Please specify your local requirement when ordering.
