The Threaded Pipe Heat Exchanger uses efficient heat transfer pipe-threaded pipe as the component, the heat transfer coefficient reaches the 1-3 times of the bare pipe heat exchanger, with the less flow resistance and little power consumption. Because of the great improvement on the inner structure, the heat exchanger's all performance index is increased.The Threaded pipe heat exchanger has the stated water storage, and is widely used in the supply system of domestic hot water in the civil and industrial buildings like hotels, restaurants, organs, schools, hospitals, factories,mines and so on.The heat exchange component is made of stainless steel or red copper threaded pipe, the body 's material is carbon steel or stainless steel, may choose carbon steel with copperplate as inner liner or stainless steel plate, etc.The hot mediator is steam or high-temperature water, and the shell side's working pressure includes three grades: 0.6Mpa~1.0Mpa and 1.6Mpa.To prevent the equipment's operating under the hyperpressure condition, the displacement heat exchanger must setup the safety-insurance measures. There are many kinds of plans ready for choosing. We recommend you install the safety valves on the top of the heat exchanger; it will be economic, safe and do not need extra space.In order to control the outlet water's temperature to be in the requirement's scope, it is left an interface for the temperature sensor on the body close to heated water outlet, to control the hot mediator's flow rate effectively.The series of heat exchanger has complete types and many specifications, the following performance parameter and specification list of the catalogue is made out on the basis of regular parameter, we can also design the exchanger specially with different volume, working pressure, heat transfer area and quantity as per the user's requirement.

Structure FeaturesHigh heat exchange speed, high temperature resistance (400°C) and high pressure resistance(2.5MPa);High efficiency and energy conservation: The heat transfer coefficient reaches 3000-4000W/m2.°C in the transfer from steam to water and 2000-3500 W/m2.°C in the transfer from water to water.The pipes of heat transfer are stainless steel, so they have a long service life of over twenty years.Quantity of storage water is large: There are hardly dead water places in the heat exchanger, the availability of volume is high, water waste is small, and water supply is safe and stable.Designed flexibly,complete specifications, practical and funds can be saved.With the large water storage, the little cold water places in the heat exchangers, the high volume's availability, less water head loss; it has the safe and stable water supply effect. Flexible Design,complete specifications, practical and narrow target and saving the cost well.The heat exchanger is able to inspect water temperature continuously and automatically, then control the temperature accurately by instructing control valves to regulate the hot mediator's flow rate in the coil pipes. The temperature of outlet water can remain in the scope of 2°C of the set point under the condition of load fluctuation.Low maintain cost, easy operation, long period of cleaning fouling, and easy cleaning.
