Refrigerant tube knowledge popularization

High quality refrigerant copper pipe, high cleanliness, strong pressure resistance, in the process of operation does not break due to uneven pressure. Poor quality refrigerant copper pipe is easy to be affected by external force extrusion deformation, in the process of operation may lead to refrigerant pipe rupture, affect the effect of air conditioning refrigeration/heating. How to identify copper pipes?

Look at the color: at present, the best refrigerant copper tube is copper tube, its purity is more than 99%, known as pure copper, color rose red; Other copper pipes are mostly alloy copper pipes, such as brass pipes, composed of 7:3 copper zinc ratio, the color is yellow.

Touch by hand: the inner and outer walls of high-quality refrigerant copper pipes are smooth and clean, without sand holes, oxidation, rupture and other defects.

Bending copper pipe: high quality copper pipe after bending no crease, no deformation; Poor copper pipe after bending easy to produce crease, and easy to squeeze deformation.
