ACR Copper Pipe

-- Steady & Reliable Manufacturer --

The Precision Standard for Air Conditioning & Refrigeration

ACR Copper Pipe is a specialized grade of tubing engineered specifically for the movement of refrigerants in thermal systems. While it may look similar to standard plumbing pipe, ACR pipe is held to much tighter tolerances regarding internal cleanliness and dimensional precision. At Zhejiang Jingliang, our ACR pipes are manufactured to meet the rigorous ASTM B280 and EN 12735-1 standards. These standards dictate that the internal surface must be virtually free of any carbon residue, moisture, or oil—impurities that can react with modern synthetic refrigerants like R410A or R134a to form harmful acids. To achieve this, our pipes undergo a multi-stage cleaning process followed by bright annealing, which leaves the interior surface with a polished, chemically inert finish.

The "ACR" designation also implies that the pipe is measured by its Outside Diameter (OD) rather than the "nominal" size used in plumbing. This distinction is vital for HVAC technicians to ensure that fittings and brazing joints fit perfectly to maintain a vacuum-tight seal. We offer ACR pipes in both "Hard Drawn" straight lengths and "Soft Annealed" coils, providing solutions for both rigid mechanical room headers and flexible line sets. Our ACR pipes are tested for burst pressure and eddy-current defects, ensuring that they can withstand the high-pressure cycles of a modern heat pump or industrial chiller. By choosing Jingliang ACR Copper Pipe, you are investing in a component that maximizes the COP (Coefficient of Performance) of the entire cooling system by maintaining a smooth, non-restrictive flow of refrigerant.

Commercial Cooling and Industrial HVAC

ACR copper pipes are the primary conduits in Commercial Air Conditioning systems, including roof-top units (RTUs) and large-scale VRF systems for office buildings. In the Refrigeration sector, they are used for supermarket rack systems, cold storage facilities, and transport refrigeration (trucks and shipping containers). They are also essential in Laboratory and Medical Cooling, where temperature stability is critical. Beyond cooling, ACR pipes are used in Heat Recovery Ventilators (HRV) and industrial-scale dehumidifiers. Their high purity also makes them suitable for certain High-Vacuum Laboratory Lines and specialized compressed air systems where oil-free delivery is a strict requirement. In residential settings, they form the "High-Pressure Side" of heat pump water heaters, providing efficient thermal transfer for domestic hot water.

System Longevity and High-Pressure Safety

The primary advantage of our ACR pipe is "Internal Chemical Stability." By removing all manufacturing contaminants, we prevent the "acid-sludge" formation that leads to valve clogs and compressor failure. "Pressure Resilience" is another key factor; our ACR pipes are designed with wall thicknesses optimized for the 500+ PSI working pressures typical of R410A systems. The "Smooth Internal Bore" reduces friction loss, meaning the compressor doesn't have to work as hard, which leads to "Lower Energy Consumption." Our ACR pipes are also highly "Brazing-Friendly," with consistent metallurgical properties that allow for deep, strong capillary joints. Furthermore, the "Permanent Marking" on our pipes (size, standard, and manufacturer) provides ease of inspection and compliance for local building codes. Finally, the "Natural Antimicrobial" properties of copper help prevent the growth of mold and bacteria in the condensation-prone environments of an AC unit.

Standardized Shipping and Documentation

Straight ACR pipes are typically bundled and wrapped in heavy-duty plastic, with the ends sealed by plastic plugs. For long-distance export, we use wooden cases or steel-reinforced crates. Payment is usually T/T (30% down, 70% before shipment) or L/C. We provide full Mill Test Certificates (MTC) for every batch, detailing the chemical composition and physical test results. We ship from the Port of Ningbo, offering optimized loading to minimize freight costs. Our ACR products are recognized globally, and we provide documentation to satisfy customs and technical regulators in North America, the Middle East, and Southeast Asia.

  • Q: What is the difference between ACR and Plumbing pipe?
  • A: ACR pipe is cleaned and dehydrated for refrigeration and measured by OD. Plumbing pipe is measured by nominal size and does not require the same level of internal cleanliness.
  • Q: Do you offer ACR pipe in 6-meter lengths?
  • A: Yes, we offer standard 10ft, 20ft, 3m, and 5.8m/6m lengths to fit standard shipping containers.
