Brief introduction: Copper is light, strong, corrosion-resistance, long lasting and maintenance free. Its high thermal conductivity and ease of joining, bending and handling often make it the metal of chopice for tubing. Copper tube will not burn or support combustion or decompose to toxic gases. Therefore, it will not carry fire through floors, walls and ceilings. Volatile organic compounds are not required for installation. The high-accuracy inner grooved copper tube produced by the world advanced continuous casting and rolling production process is one of our leading products, which features uniform and compact structure, high dimensional accuracy, standard and complete tooth shape, low inner cavity residue and so on. Its internal surface area is 65-100% more than that of the plain copper pipe with the same specification. Its heat transfer coefficient is 1.8-2.0 times higher than that of the plain pipe with the same specification. It is widely used for air conditioning and refrigeration industry, and adapts to the efficient, energy-saving and healthy development trend of air conditioners.
