Rifled tube

Rifled tube is also called dry steam pipe, inner rib pipe or inner fin pipe. In the central air conditioning machine, it is mainly applied to dry evaporator, heat exchange, the water outside the tube is cooled by the refrigerant of evaporation expansion in the tube; It is also used in home and commercial air conditioning heat exchangers or in high heat pipes.

 

The inner surface area of rifled tube per unit length is 1.5-2 times that of ordinary smooth copper tube, its heat transfer coefficient is 1.5-2.4 times that of the same specification smooth copper tube, and the carrier flow resistance is only increased by 3-5%, 20-35% energy saving, and the weight of refrigeration and air conditioning machine is reduced by 10-25%. Rifled tubes are usually delivered in straight strips for easy installation. The size range of internal threaded pipe is shown in the chart below. Specific tooth shape parameters and pipe end requirements can be customized according to customer requirements.
