We specialize in comprehensive product lines including insulated copper pipes, air conditioner connecting pipes, air conditioner copper tube, copper plates, Copper strips, Copper bars, and Copper sheets - all engineered to exacting international standards for critical applications across refrigeration systems, HVAC, power transmission, electrical engineering, shipbuilding, mechanical manufacturing, and rail infrastructure etc.

Our core manufacturing philosophy combines material science innovation with rigorous quality control. The insulated copper pipes feature a multi-layer construction: C12200 copper cores (ASTM B280 compliant) cold-drawn to ± 0.03mm tolerance, surrounded by cross-linked polyethylene foam insulation and finished with UV-stabilized PVC jackets. Similarly, our air conditioner connecting pipes undergo precision electropolishing to achieve internal surface roughness below Ra 0.8μ M, ensuring optimal flow dynamics for R410A and R32 refrigerants while maintaining brazing-ready ends for leak-proof installations per specifications.
