It is easy to increase or decrease the heat transfer area of ​​the tube heat exchanger. When the heat exchanger needs to increase the liquid processing capacity, the original heat transfer area will basically not increase, but the heat transfer area of ​​the heat exchanger can easily increase, thereby increasing the processing capacity.
Only the shell plate of the heat transfer plate is exposed in the air, the heat dissipation loss is negligible, and no insulation measures are required. One of the characteristics of the heat exchanger in terms of operation and maintenance is that it is relatively easy to assemble and disassemble. You can remove the plates for cleaning, replace the gaskets, and even replace the plates by loosening the pressing bolts without dismantling them. This is very important for materials that are prone to deposits in the heat exchange medium. Allowable temperature and pressure: It is used to rely on the gasket between each two plates to prevent material leakage, so the total length of its sealing periphery is very long.
The temperature, pressure and chemical stability that the gasket can withstand often become its temperature and pressure range and the allowed material range. In addition, due to the small gap between the heat transfer surfaces and the unevenness on the heat transfer surface, the pressure loss is larger than that of the traditional smooth one. In addition,Tube and tube heat exchangerWork stress is lower.
The tube heat exchanger does not use non-metal sealing materials and can have higher temperature resistance and pressure resistance. Applicable to operating temperature300℃,pressure3.0Mpaworking conditions.
