Plate heat exchanger with high safety requirements

August 31, 2023

In process industrial equipment. When the gasket is damaged, the gasket plate heat exchanger is a device with high safety requirements. The appearance of external drip is visible in the heat exchanger, heat exchanger, etc., there will be slight dripping at the beginning, and in the process equipment with large pressure shock, there may be a large leak due to the damage of the gasket. Under strong pressure shocks, the gasket can sometimes be removed from the correct position of the plate heat exchanger.
Typically, the heat exchanger sheet set can be tightened again in the event of a small amount of dripping. Thereby increasing the stress between the various gaskets, some plate heat exchangers which have found that the heat exchanger seals fail by the dripping during the cold movement of the process equipment or the dripping during the parking cooling process have the function of secondary regulation. Solve the phenomenon of dripping in a short time. In the newly assembled heat exchanger, a larger combined length dimension can be used, and when a drip occurs, the sets of plate heat exchangers are tightened, using a longer combined length dimension. The maximum combined length dimension and the minimum combined length dimension are generally visible on the nameplate of the heat exchanger and should not be less than the minimum combined length dimension. When the combined heat exchanger reaches the minimum combined length dimension and still leaks, the gasket must be changed.
A company is a professional enterprise in the commissioning service of plate heat exchangers. Developed its own unique and effective low-cost heat exchanger to provide maintenance services for the plate heat exchangers of various process companies. In cooperation with different process industry users. Heat exchanger, cleaning, inspection and rubber seal replacement technology. The main methods of rubber parts replacement technology are:
1. Inspection and testing of reuse performance. The wall thickness of the heat exchanger and the pipe is checked in case of rust.
2. Remove aging seals. The acid-alkali cleaning tank jointly developed with Haug Chemical Co., Ltd. was used for chemical cleaning according to different soils. The appearance of the parts being cleaned is not corroded by chemical media such as gasoline. The chemical medium remaining on the surface of the plate heat exchanger or the like is completely removed by a high pressure purging device.
3. Perform chemical cleaning.

4. Each heat exchanger plate is coated with a fluorescent test agent. Partially cleaned again. In addition, under the irradiation of ultraviolet light, it is checked whether there are fine cracks and corrosion holes. Also check the condition of the seal groove and trim if necessary.
5. For bonded gaskets. Re-bonding with a blending adhesive will completely remove residual material. The recombined heat exchanger chip sets are clamped in a special fixture to cure the adhesive; the heat preservation furnace is heated and insulated to achieve the best bonding effect. For non-adhesive gaskets, different devices are used to secure the gasket in the heat sink.
6. Check the bonding position and bonding quality of each plate type heat sink. Then carefully assemble the plate heat sink set carefully. Sort by device order.

Except for gasket plate heat exchanger, our main products include brazed plate heat exchanger,shell and tube heat exchanger, etc.
