ASTM A213 T5 Heat Exchange Tube Introduction:
ASTM A213 T5 heat exchange tube material is mainly composed of two elements: chromium and molybdenum. Chromium is an element with good corrosion resistance. It can effectively improve the high temperature resistance and corrosion resistance of materials, and at the same time increase the strength and hardness of materials. Molybdenum is an element with excellent high temperature resistance and corrosion resistance. It can improve the corrosion resistance of materials and has good hardness and ductility. The addition of these two elements makes ASTM A213 T5 heat exchange tubes have excellent high temperature resistance and corrosion resistance, and are suitable for various harsh working environments.
ASTM A213 T5 Heat Exchange Tube
According to the ASTM A213 T5 standard, the chemical composition of the heat exchange tubes must meet strict requirements. Among them, the content of chromium is 4.00-6.00%, and the content of molybdenum is 0.44-0.65%. In addition, the content of some other elements is also specified in the standard, including carbon, silicon, manganese, phosphorus, sulfur, etc. Reasonable control of these elements can ensure that the heat exchange tube material has good processability and mechanical properties.
The surface treatment of ASTM A213 T5 heat exchange tubes is also very important. According to the requirements of the standard, the outer surface of the heat exchange tube should be cleaned and shot blasted to remove pollutants such as rust and grease, and to improve the surface roughness of the tube. In addition, the inner surface of the heat exchange tube should be chemically cleaned and pickled to remove oxides and dimensional errors on the inner wall and improve the smoothness of the inner surface of the tube.
ASTM A213 T5 Heat Exchange Tube
In conclusion, ASTM A213 T5 heat exchange tubes, as a seamless chromium-molybdenum alloy steel pipe under high temperature and high pressure conditions, has excellent high temperature resistance, corrosion resistance and pressure resistance. It has strict requirements in terms of chemical composition, mechanical properties, processing technology and surface treatment to ensure its quality and reliability. In various high temperature and corrosive environments, ASTM A213 T5 heat exchange tubes can exert their excellent performance and are widely used in petroleum, chemical, electric power and nuclear industries and other fields.
