Classification: Condensing tube series, mainly used in suspended matter more than 500PPM of rivers, seawater or coastal groundwater for the cooling medium of various heat exchangers and condenser condensing tube series, the main chemical composition of the alloy is: Cu, As, the margin is Zn. The product is generally used in inland power plants without suspended solid corrosion of fresh and clean water in rivers, lakes and springs, and can also be used in other liquid and juice processing equipment.
In addition, the product is widely used in the sugar and food industries, where arsenic prevents leaching of zinc and, when fully annealed, prevents stress corrosion cracking, pitting and etching. Condensing tube series, the main chemical composition of the alloy is: Ni,Fe,Mn, margin Cu. The addition of Fe and Mn in this alloy greatly improves the corrosion resistance of this material. In clean seawater, the alloy can receive a flow rate of 2.2-2.5%/s. In a slightly saline solution, the acceptable speed can reach 4m/s. The alloy avoids stress corrosion cracking and nickel removal at high temperature points.
Therefore, the alloy has good corrosion resistance to clean or polluted sea water and river and bay water, and is widely used in power stations, desalination, petrochemical plants and other heat exchangers using sea water. Hsn70-1B pipe is characterized by the formation of a smooth, uniform, strong 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, not easy to scale, brass pipe is conducive to increasing the thermal conductivity of copper pipe, improve the service life. 2) The Hsn70-1AB new alloy condensate pipe is based on a single type 2 alloy Cu-Zn-Sn series, and adopts the synergistic effect of As, B, Ni and Mn elements to achieve multi-component solution strengthening and improve the corrosion resistance and erosion corrosion resistance. Condensing tube series, the main chemical composition of the alloy is: Ni, Fe, Mn, margin Cu. The addition of Fe and Mn in this alloy greatly improves the corrosion resistance of this material, avoiding stress corrosion cracking and high temperature point nickel removal. Therefore, the alloy has good corrosion resistance to clean or polluted seawater and river and bay water, and is mainly used in heat exchangers for thermal and atomic power generation condensers, water supply heaters, stills, oil coolers, and distilled water devices. Brass tube is mainly used in electronic technology, construction, pen and other industries, brass tube is made of brass as raw materials, and brass is a yellow copper zinc alloy, in addition to containing copper, some also contain other metal impurities, if the use of high quality brass to make brass tube, swear will affect the quality of brass tube, brass quality directly determines the quality of brass tube. In particular, China put forward the slogan of environmental protection and energy saving during the eleventh Five-Year Plan period, environmental protection products have risen to a height again, and brass pipes made of brass containing more impurities are not environmentally friendly, and environmental protection products that meet environmental protection standards are the favorite of enterprises.
