Hard-Drawn Copper Round Pipe 10mm-50mm, ASTM B88, Industrial
Refrigeration Systems
Our hard-drawn copper round pipes, compliant with ASTM B88 standards, are precision-engineered for industrial refrigeration and
high-pressure cooling systems. Available in diameters from 10mm (≈0.39") to 50mm (≈1.97"), these pipes combine exceptional strength, leak-proof performance,
and thermal efficiency. Manufactured from phosphorus-deoxidized
copper (Cu-DHP), they withstand extreme temperatures and mechanical
stress, making them ideal for ammonia, CO₂, and Freon-based
refrigeration applications.

3. Competitive Advantages
① ASTM B88 Compliance
Guaranteed adherence to global refrigeration-grade specifications,
ensuring compatibility with ammonia, hydrocarbons, and synthetic
refrigerants.
② High-Pressure Durability
Hard-drawn temper (H80) provides superior resistance to vibration,
thermal cycling, and mechanical wear in harsh industrial
environments.
③ Zero-Leak Guarantee
Seamless construction and ultrasonic testing eliminate risks of
cracks or pinholes, critical for maintaining refrigerant integrity.
④ Rapid Customization
Tailored lengths (up to 12m), end finishes (flared, grooved), and
insulation-ready surfaces to meet OEM or retrofit project needs.
⑤ Global Compliance
Certified for use in EU, North America, and Asia-Pacific markets,
reducing import delays and compliance risks.
4. Key Applications
- Industrial Chillers: High-pressure refrigerant lines for large-scale cooling in
manufacturing plants.
- Cold Storage Facilities: Reliable ammonia (NH₃) piping for freezer warehouses and food
logistics centers.
- Heat Pump Systems: Durable connections for geothermal and air-source heat pumps in
commercial HVAC.
- Chemical Processing: Corrosion-resistant tubing for CO₂ and glycol-based cooling
circuits.
- Marine Refrigeration: Saltwater-resistant copper pipes for shipboard refrigeration and
AC systems.
