Condenser tube series, mainly used in rivers with suspended solids greater than 500PPM, sea water or coastal groundwater as the cooling medium of various heat exchangers and condenser condenser tube series. The main chemical composition of the alloy is: Cu, As, and the balance is Zn. This product is generally used in inland power plants with fresh and clean water in rivers, lakes, and springs without corrosion by suspended solids, and can also be used in other liquid and juice processing equipment.
In addition, the product is also widely used in the sugar and food industries. In these environments, arsenic can prevent the leaching of zinc, and after full annealing, it can also prevent stress corrosion cracking, pitting and erosion. Condenser tube series, the main chemical composition of the alloy is: Ni, Fe, Mn, the balance Cu. The addition of Fe and Mn in the alloy greatly improves the corrosion resistance of this material. In clean seawater, the alloy can accept water flow rates up to 2.2-2.5%/s. The acceptable speed can reach 4m/s in the salt solution. The alloy can avoid stress corrosion cracking and high temperature point denickel.
Therefore, the alloy has good corrosion resistance to clean or polluted sea water and river bay water, and is widely used in heat exchangers that use sea water such as power stations, desalination and petrochemical plants. The characteristic of Hsn70-1B pipe is that it can form a smooth, uniform, firm and dense protective film on the inner surface of the copper pipe under the water quality conditions of the power plant. Long-term use in fresh water, it is not easy to scale. The brass tube is beneficial to increase the heat conduction efficiency of the copper tube and improve the service life. 2) The Hsn70-1AB new alloy condenser is based on the single type 2 alloy Cu-Zn-Sn system, and uses the synergistic effect of As, B, Ni, and Mn to achieve multiple small solid solution strengthening and improve corrosion resistance and resistance Technology for erosion corrosion performance.
Condenser tube series, the main chemical composition of the alloy is: Ni, Fe, Mn, the balance Cu. The addition of Fe and Mn in the alloy greatly improves the corrosion resistance of this material, and can avoid stress corrosion cracking and high temperature spots Denickeling. Therefore, the alloy has good corrosion resistance to clean or polluted sea water and river bay water, and is mainly used for heat and heat in condensers for nuclear power generation, water supply heaters, distillers, oil coolers, distilled water devices, etc. Switch. Brass tubes are mainly used in electronic technology, construction, pen-making and other industries. Brass tubes use brass as raw materials, and brass is a yellow copper-zinc alloy. In addition to copper, some also contain other If you use brass with high impurity content to make brass tubes, it will definitely affect the quality of brass tubes. The quality of brass directly determines the quality of brass tubes. Especially during the Eleventh Five-Year Plan period, the slogan of environmental protection and energy saving was put forward, and environmentally friendly products have risen to a high level again, and brass tubes made of brass with more impurities are not environmentally friendly, and environmentally friendly products that meet environmental protection standards are the company’s Favorite.
