High temperature steam heating heat transfer oil conditions, how would you choose a plate and shell heat exchanger and a shell and tube heat exchanger

At present, among the many types of heat exchangers, the working conditions of high-temperature steam heating heat transfer oil are generally two, one is the shell-and-tube heat exchanger, and the other is naturally the plate heat exchanger.A plate and shell heat exchanger with the advantages of a heat exchanger and a shell-and-tube heat exchanger. How should I choose these two heat exchangers?


Let’s talk about the shell-and-tube heat exchanger first. This working condition is nothing more than the fact that the detachable plate type cannot be used because of the stable operation of the high-temperature steam. The advantage of the shell-and-tube heat exchanger lies in its fully welded form and no rubber strips.
It can meet the requirements of high temperature and high pressure resistance, but because of the internal structure, heat exchange efficiency and cleaning will be its weaknesses, but the overall price of the shell-and-tube type will be relatively low.

What about plate and shell heat exchangers?
From the welding form, it has all the advantages of the tube heat exchanger. The two versions of fully welded and detachable can not only meet the requirements of high temperature and high pressure resistance and disassembly and cleaning, but also cannot achieve the heat exchange effect in the shell and tube type.
Under the disadvantages of the herringbone corrugated plate structure, the medium forms turbulence during the heat exchange process, and has the characteristics of high efficiency of detachable plate heat exchange. However, in terms of price, the production of plate and shell heat exchangers
It is technically difficult to achieve the heat exchange effect while ensuring that the equipment does not leak, which is currently impossible for many manufacturers.


In recent years, among the customers that we have contacted Qingdao RPT, in the working conditions of high temperature steam heating heat transfer oil, everyone has begun to generally prefer to choose plate and shell heat exchangers with good heat exchange effect and long service life.
At the same time, you are also pursuing the improvement of efficiency. You who are in need of heat exchangers, are your ideas also following the development of the times and coincide with the development trend of the market?
