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.
