Precision performance of tin brass tube

High precision tin brass tube is a color metal air conditioning copper tube that has undergone precision mechanical processing. It has the characteristics of high precision size, good mechanical properties, easy cutting, high thermal conductivity, high tensile strength and good sea level corrosion resistance. Tin brass tube has good mechanical properties, as corrosion resistant parts of cargo ships and sea level, steam, vacuum residue contact plastic hose, thermal insulation mechanical equipment parts.

High precision alloy pipe widely used in electric power installation engineering (power plant, nuclear power plant, etc.) oil engine generators, petrochemical equipment transportation, seawater desalination equipment, fuqing city, production, processing and manufacturing, ship design such as industrial production in the production and processing of the sea, important for the production of processing and manufacturing to touch corrosive chemicals of all kinds of cooling tower, heat exchanger, condenser, Pipeline systems such as distribution oil pipelines, filtration systems, pumps and oil circuit boards and other prefabricated components.

With the development trend of related aspects, especially the rapid development trend of electric power installation engineering, shipbuilding and subsea industrial production, the sales market demand of high precision tin brass tube is increasing rapidly. The tin brass tube itself is particularly sensitive to intercrystalline corrosion cracking, which can be caused by the presence of abundant tensile stress and etching chemicals containing ammonia.

It has caused the cracking of tin brass tube in the air pumping area of condenser, and a part of copper tube produces large tensile stress, coupled with the high ammonia composition in the air pumping area, after a period of operation, the intergranular corrosion is intensified, and then leads to the cracking of copper tube.
