a. High Heat Exchange Coefficient:The threaded pipes is made of stainless steel or red copper,is the high efficient heat exchange component of integrating with inside and outside thread.It has the high heat exchange coefficient.With such threaded pipe’s help,the threaded pipe heat exchanger will form the strong turbulent flow under the condition of little fluid resistance force.Thereby the heat exchange coefficient is greatly increased for both inside and outside of the pipes.It has been confirmed that the total heat exchange coefficient reaches 3000~6000W/m2°C in the exchange test of steam to water and 2500~5500 W/m2°C in the exchange test of water to water.
b. Compact Structure:The heat transfer area of the product is bigger per unit volume.The total heat exchange coefficient is high,so it will save floor space and more materials.
c. Less Solid Fouling:the threaded pipe have full of convex concave structure specially.It causes scour effect by much flow layer and revolving flow inside and outside of the pipes.Besides this,the pipe expands with heat and contracts with cold.The impurity and fouling will not be remained in or out of the pipe wall,so it can work well for a long period of time.
d. Not easily leak: the product have short seal perimeter.The thick thread pipe just like expansion joints,have the capability of compensating themselves;the heat exchanger have little heat stress.It will not leak easily.
e.Convenient Installation: The heat exchanger has two type including horizontal and vertical styles, so it can be installed in different locations conveniently
