304 Stainless Steel 900mm Diameter Steam Vent Condenser

Steam Condenser,Material Is Carbon Steel,Rendering Plant Machine,For Condense The Steam

    The material of the condenser is generally carbon steel, stainless steel and copper. When the tube sheet made of carbon steel is used as a cooler, the welds between the tube sheet and the tube often show corrosion and leakage. The leakage into the cooling water system will cause Cause environmental pollution and waste of materials.

    Protective coating of polymer material for condenser Protective coating of polymer material for condenser When the condenser is manufactured, manual arc welding is generally used for the welding of the tube sheet and the tube, and the weld shape has different degrees of defects, such as depressions, pores, slag inclusion, etc., and the weld stress distribution is not uniform.         When in use, the tube sheet is partly in contact with industrial cooling water, and the impurities, salts, gases, and microorganisms in the industrial cooling water will cause corrosion to the tube sheet and welds.

    Studies have shown that industrial water, whether it is fresh water or sea water, will have various ions and dissolved oxygen. The changes in the concentration of chloride ions and oxygen play an important role in the corrosion shape of metals. In addition, the complexity of the metal structure also affects the corrosion form. Therefore, pitting corrosion and crevice corrosion are the main corrosion of welds between tube sheet and tube. From the outside, there will be many corrosion products and sediments on the surface of the tube sheet, and bubbles of different sizes are distributed.

    When seawater is used as the medium, galvanic corrosion will also occur. Bimetal corrosion is also a common phenomenon of tube sheet corrosion. In view of the anti-corrosion problem of condensers, western countries mostly use polymer composite materials for protection, and the most widely used technology products. It has excellent adhesion performance, temperature resistance and chemical corrosion resistance. It can be used safely in a closed environment without shrinking. In particular, it has good isolation of bimetallic corrosion and erosion resistance, which fundamentally eliminates the corrosion of repaired parts. Leakage provides a long-term protective coating for the condenser.
