For over 15 years, Shandong Ying Yi Import & Export Co., Ltd. Has stood at the forefront of copper product manufacturing and international distribution. 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.
Shandong Ying Yi remains dedicated to its founding principles: "Innovation as our eternal theme, excellence as our constant pursuit. " We allocate 5% of annual revenue to R&D initiatives exploring many different industries. Our customer-centric approach combines technical consultation for different environment application analysis and life cycle support including 10-year corrosion warranties.
