HSn70-1AB Brass Tube For Corrosive Liquids In High Strength And Corrosion Resistant Condenser
1. Description
HSn70-1AB alloy condenser tube is a new type of alloy pipe. It is based on copper, tin and zinc alloy, with the synergistic effect of arsenic, boron, nickel and manganese elements. It has high corrosion resistance and erosion corrosion resistance.
It's belonged to condensing tube series, the chemical composition of the HSn70-1AB alloy tube is copper and arsenic, and the residual is zinc. Its superior performance is to prevent stress corrosion cracking, pitting, and erosion. The product is generally used in rivers, lakes and springs, as well as inland power plants with fresh and clean water. In addition, it can also be used in liquid and juice processing equipment, and also widely used in sugar and food industry.
Our company's brass tube grades mainly include HAi77-2,HSn70-1, HSn70-1B, HSn70-1AB, H68A copper tube, fin tube and U-tube. The products are produced in strict accordance with the standard, and the finished products can be tested by the third party according to the customer's requirements. These copper tubes are mainly used in power plants, desalination, petrochemical, mechanical ships and automotive heat exchangers. We have rich production experience, professional technology, excellent equipment, superior quality, reasonable price, high-quality service, so that our products sell well all over the world, well received by customers.
