The stiffness of the spiral plate heat exchanger
Feb 06, 2021

The spiral body is an elastic body. For such an elastic member, when it is compressed, it is easy to be crushed, making the equipment unable to operate normally. One way is to increase the thickness of the spiral body, which is uneconomical; the other way is to increase the number of spacers. Reduce the distance between the spacers. In this way, the rigidity and pressure bearing capacity of the spiral plate can be improved. There are two methods of welding with fixed distance columns. One is to use manual welding to weld the fixed-distance column to the ten helix; the other method is to use the contact welding technology (stud welding) for the fixed-distance column, which contacts the fixed-distance column.
