Analyzing The Common Faults Of Plate Heat Exchangers, How Do We Usually Handle Them

Due to the erosion of water, cavitation, and corrosion by trace chemical media on the tube plates of plate heat exchangers, leakage often occurs at the weld seams of the tube plates, resulting in mixing of water and chemical materials. The production process temperature is difficult to control, resulting in the generation of other products and seriously affecting product quality.

After the leakage of the tubesheet weld seam of the plate heat exchanger, internal stress is easily generated inside the tubesheet, causing leakage in other products. Repeated repair welding and experiments require 2-4 people to complete the repair in a few days. After a few months of use, the tubesheet weld seam corrodes again, causing waste of manpower, material resources, and financial resources for the enterprise, and increasing production costs. By improving the corrosion resistance and erosion resistance of polymer composite materials, as well as protecting the plate heat exchanger in advance, this not only solves the problems of welding seams and sand holes, but also prevents the use of chemical substances to corrode its metal surface and welding points. In future regular maintenance, polymer composite materials can also be applied to protect the metal; Even if leakage occurs after use, it can be repaired in a timely manner, eliminating the impact of long-term welding repairs on production.
