Name: Cu-Ni (Stainless Steel) Grooved Pipes 

Grade: Cu-Ni (a new grade of stainless steel especially designed for air conditioning industry)

Dimension: OD7x0.4mm, OD7x0.35mm, etc.

Refrigerants: Compatible wih all common refrigerants such as R410/R32/R22, etc.

Features: Cu-Ni chemical composition is higher Cu content, lower C and N contents in order to achieve exceptional ductility and corrosion resistance. Compared with copper pipes, it’s with better corrosion resistance and same (even better) ductility. The inner groove designs also increasingly improve the heat transfer efficiency. More importantly, it’s able to save energy (under heating mode) and great costs than copper pipes. Cu-Ni is a perfect substitute for copper for air-conditioning industry.
