Transfer of second-hand 350 square meter stainless steel condenser

Transfer of second-hand 350 square meter stainless steel condenserThe materials used are generally carbon steel, stainless steel, and copper. When carbon steel tube sheets are used as coolers, corrosion and leakage often occur at the welds between the tube sheets and the tubes. The leaked material entering the cooling water system can cause environmental pollution and material waste.

During the production of the condenser, manual arc welding is generally used for the welding of the tube plate and the column tube. The shape of the weld seam has varying degrees of defects, such as dents, pores, slag inclusions, etc., and the distribution of weld stress is also uneven. When in use, the tube plate comes into contact with industrial cooling water, and impurities, salts, gases, and microorganisms in the industrial cooling water can cause corrosion to the tube plate and welds. Research shows that industrial water, whether it is freshwater or seawater, will have various types

The concentration changes of ions and dissolved oxygen, including chloride ions and oxygen, play an important role in the corrosion shape of metals. In addition, the complexity of the metal structure can also affect the corrosion morphology. Therefore, the corrosion of the welds between the tube plate and the column tube is mainly caused by pitting corrosion and crevice corrosion. From the outside, there will be many corrosion products and deposits on the surface of the tube plate, distributed with bubbles of varying sizes. When using seawater as a medium, galvanic corrosion can also occur. Bimetallic corrosion is also a common phenomenon in tube plate corrosion.

Transfer of second-hand 350 square meter stainless steel condenserRegarding the anti-corrosion issue of condensers, the West often uses polymer composite materials for protection, with technical products being the most commonly used. It has excellent adhesion performance, temperature resistance, and chemical corrosion resistance. It can be safely used in a closed environment without shrinkage, especially with good isolation of bimetallic corrosion and erosion resistance, fundamentally eliminating corrosion leakage in the repaired area and providing a * protective coating for the condenser.
