seamless copper pipe for air conditioner – Various types of dental patterns is produced to meet different customers’ need. It is of high-precision and efficiency. Compared with a plain copper tube, its heat transfer coefficient can be 2.5-4 times as that of it.
Internal thread copper tube refers to the outer surface is smooth, the inner surface has a certain number, certain rules of thread thread TP2 copper tube. Due to the increase in the inner surface area of the internal thread copper tube, its thermal conductivity is 20 to 30 percent higher than that of the light pipe. With the world energy shortage and domestic energy efficiency than the implementation of air conditioning access system, the internal thread brass will be widely used in air conditioning and refrigeration industry.
