Ordinary heat exchangers adopt common carbon steel or regular steel structure. They will suffer pitting corrosion, rust and perforation when exposed to corrosive medium, which threatens whole production line. It is necessary to use corrosion resistant heat exchanger for specific working scenarios. As a professional manufacturer, we sort out typical applicable conditions.
Chemical production is a main application field. Process fluid contains acid, alkali and various chemical salts. Conventional heat exchange equipment will be corroded rapidly. Wastewater treatment projects also require anti‑corrosion equipment. Waste water carries chloride ion, organic impurity and corrosive ion. Long‑term operation will destroy common metal surface. Seawater and brine cooling system belongs to high‑chloride working condition. Chloride ion easily causes pitting corrosion on ordinary steel. Some metallurgical and mining process produce corrosive process liquid, which will shorten service cycle of standard equipment.
If the medium contains corrosive components, or working environment has humid salt mist, corrosion risk cannot be ignored. Using ordinary heat exchanger will bring frequent maintenance, leakage risk and unplanned shutdown. Even if corrosion sign is not obvious in early stage, hidden damage will accumulate continuously. Customers shall evaluate corrosion risk in early project design stage. We support project assessment, and provide corrosion resistant heat exchanger for high‑risk working conditions to secure continuous production.
