A brief introduction to the application characteristics of fully welded plate heat exchangers
2020-07-02
Due to the good welding process used in fully welded plate heat exchangers, there are no non-metallic sealing materials between the heat transfer elements, resulting in high temperature, pressure, and corrosion resistance. The working temperature can reach up to 500 ℃, and the working pressure can reach up to 2.5Mpa, providing a large heat transfer area in a compact space, which enhances the reliability of the heat exchanger.
Due toFully welded plate heat exchangerthe use of good welding technology, there are no non-metallic materials sealing between the heat transfer elements, so the temperature resistance, pressure resistance, and corrosion resistance are relatively high, with a working temperature of up to500℃, and a working pressure of up to2.5Mpa, providing a large heat transfer area in a compact space, improving the reliability of the heat exchanger.
Fully welded plate heat exchangerThe main characteristics are as follows:
(1High heat transfer efficiency
Fully welded plate heat exchangerThe heat transfer plates can generate strong turbulence at lower flow rates, thanks to the special stainless steel pressed material and the unique corrugated structure design of the plates, thereby increasing the heat transfer performance of the fluid and greatly improving the heat transfer efficiency. Under the same conditions, the heat transfer coefficient is generallyFully welded plate heat exchangermore than 1-3 times that of shell-and-tube heat exchangers.1-3times.
(2Low pressure loss
Under the same heat exchange area,Fully welded plate heat exchangerthe flow area is about5larger than that of shell-and-tube heat exchangers, resulting in lower pressure loss.
(3Low fouling thermal resistance
Fully welded plate heat exchangerThe plates have a soft heat transfer surface, with a higher turbulence level, significantly reducing fouling, and the fouling thermal resistance is only1/4-1/5that of shell-and-tube heat exchangers.
(4Compact fouling, small footprint
Due to the high heat transfer coefficient of the heat transfer elements, compared to shell-and-tube heat exchangers,Fully welded plate heat exchangerthe structure is lightweight and compact, requiring less installation space, greatly saving users' equipment installation space and investment costs, and facilitating the deployment and use of large heat exchangers.
Fully welded plate heat exchangerCurrently widely used in gas-gas heat transfer, gas-liquid heat transfer, and liquid heat transfer, playing a significant role in the oil and gas industry, pharmaceutical industry, power plants, metallurgical and chemical industry, automotive, pulp and paper industry, and steel industry.
