Small cylinders or rectangles can be welded to the spiral plate heat exchanger. Its function is to maintain the distance between spiral plates and keep the distance between them consistent. It can greatly improve the rigidity, stability and strength of the spiral plate, and can also promote the flow of fluid and enhance its heat transfer effect. When most manufacturers use a fixed distance, it is caused by the concentricity of automobile manufacturing. Its center part will leave a residual bulge. In the volume of the spiral plate, the damage of the plate surface to the plate is very large, and the bearing capacity can be reduced. Semicircular simplified body. The blanking and shaping industry can effectively solve this problem.

The settlement column is usually arranged in a triangle. The distance between them is related to the design pressure. The smaller the pressure, the smaller the distance between them. On the other hand, the smaller the pressure is, the smaller the distance is. We usually use 100 × 200, 150 × 150, 100 × 100 and 80 × 80。 The distance between the diameter and height of the cylinder is usually equal to that of the cylinder. The distance deviation between the fixed distance of the spiral plate of the spiral plate heat exchanger and the column is+2.0mm, and the fixed distance is the distance between the center of the column and the joint edge of the plate. S is less than 20mm.

Welding slag and other impurities shall be located clearly before rolling the spiral. When the spiral plate heat exchanger rolls, the distance column cannot fall off. If it falls off, it should be repaired.
