PTFE Heat Exchanger Using Advanced Welding Process
PTFE heat exchanger with polytetrafluoroethylene thin-walled capillary, to make up for the shortcomings of plastic thermal conductivity low, to overcome the liquid laminar flow phenomenon, that is, to play a strong corrosion resistance of PTFE, but also improve the heat transfer efficiency And the same size of the heat transfer area. Heat exchanger using advanced welding technology, to overcome the previous polytetrafluoroethylene heat exchanger welding leakage problem, PTFE Tetrafluoroethane Heat Exchanger the welding strength of up to 1.5MPa.
PTFE heat exchanger is divided into tube-type and shell-and-tube; tube bundle is the heat exchanger is installed directly in the heat exchanger solution to the container, to achieve the exchange of heat. Tube-shaped heat exchanger installation, easy maintenance, easy to use; tube-type heat exchanger with a plate (placed on the side of the groove) W-shaped, U-shaped, L-shaped (placed at the bottom), in shape or garden, Shaped and other special shape, PTFE Tetrafluoroethane Heat Exchanger can also be formed according to the requirements of customers
. Small size, light weight, compact structure, fluorine plastic thermal conductivity is low, only 0.19W / m. ℃, for ordinary carbon steel 1/250. In order to reduce the wall heat resistance, improve the total heat transfer coefficient, the general use of thin-walled tube, in order to ensure the strength of thin-walled tube, should adopt a small diameter tube. As a result of the use of a large number of small diameter tube, the volume of heat transfer per unit volume is large. Example: the same 10 square meters of tetrafluoroethane heat exchanger and metal or non-metallic graphite heat exchanger compared to the weight and volume of tetrafluoroethane heat exchanger is only the other two of the two or so. It can be seen that this heat exchanger can be small and lightweight, thus saving transportation, PTFE Tetrafluoroethane Heat Exchanger installation and operation costs.
PTFE heat exchanger adaptability. As the fluorine plastic pipe is soft, the bending fatigue life is 100,000 times, the impact strength is 1.09J / cm³ at -57 degrees, and 1.63J / cm³ at 23 degrees, so the tube bundle can be made into various special shapes , PTFE Tetrafluoroethane Heat Exchanger And in the fluid impact and vibration conditions, long-term reliable operation. This is graphite, glass, ceramics and rare metals and other corrosion-resistant materials difficult to do.
Tetrafluoroethane heat exchanger life, easy maintenance, tetrafluoroethane heat exchanger research and development of a great foundation and improve the heat exchanger is prone to aging, corrosion and other components step by step gradually improved in the original Based on the further update, better to adapt to our customers, so far, many manufacturers use tetrafluoroethane heat exchanger more than 5 years, PTFE Tetrafluoroethane Heat Exchanger so that only the heat exchanger in this regard to save a large part of the expenditure The Second, the tetrafluoroethane heat exchanger easy maintenance, if the use of leakage in the process, you can directly in the field maintenance, test pressure. Thus saving the customer back to the factory maintenance of the time round and its parking caused by the loss of production, which is difficult to do other heat exchanger.
Cost objective, as the heat transfer element of fluorine plastic, although the current price is still expensive, but the use of small diameter thin-walled tube, the overall heat transfer coefficient can be as high as 500W / ㎡. ℃, in a better manufacturing process conditions for mass production of this change Heaters, and more importantly, superior corrosion resistance can replace rare metals, thus saving a lot of rare metal consumption. In addition, due to fluorine plastic heat exchanger corrosion resistance and anti-fouling, etc., PTFE Tetrafluoroethane Heat Exchanger in the course of the use of other economic benefits can be obtained. So the comprehensive manufacturing, installation, operation and maintenance and other factors, the actual cost is lower.
The above advantages have been used in industrial production of fluorine plastic heat exchanger completely confirmed that in foreign countries it has long been widely used in a variety of media.
