The application of seamless steel tube in the field of solar energy: seamless steel pipe has been expanded a little bit in the application field, and its various characteristics have been fully played in various fields. Now it is also being used in solar power production and manufacturing. However, because the asset energy and technical energy of manufacturers are different, the requirements for seamless steel tubes are not uniform.
At the present stage, there are three kinds of key commodities in the sales market of electric water heater, which are natural gas water heater, household water heater and solar power electric water heater. Solar electric water heater is generally composed of hot plate, insulated water storage tank, connecting pipe, support frame and automatic control system. Among them, the vacuum solenoid valve, water storage tank and other accessories are rectangular frame seamless steel tube. But each processing technology is not the same, the requirements for seamless steel pipe are not the same. Today’s requirements are that some famous brand companies require relatively stable seamless steel pipes, and the way is smooth, so the quality is also ensured. Straight welded steel pipe can be divided into round, square or special-shaped pipe according to its shape.
For seamless steel tube produced in the hooves and crystal defects, parts and other crystal defects, generally use heat treatment or heat treatment and other heat treatment methods to eliminate all aspects. The purpose of heat treatment is to promote crystallization, eliminate microstructure defects, reduce compressive strength, improve plastic deformation, and facilitate cold drawing. In the processing and manufacturing of cold-drawn seamless steel tubes, heat treatment machinery and equipment should not be lacking. Therefore, to formulate the appropriate annealing process is a necessary condition to ensure that the seamless steel tube structure is qualified and the product does not crack defects. If the processor in order to better reduce the product cost and reduce the heat treatment process, it will eventually have a bad impact on the product quality.
