304 stainless steel precision tube has a wide range of uses, especially in the electrical industry, where it has its presence. Stainless steel can gain a firm foothold in the electrical appliance industry due to its safety, health, and corrosion resistance. Let me introduce some representative applications.

    The first is the parts that are in direct contact with food-the outlet pipe of the electric water pump. The water pump is very suitable for people who open shops, small companies, and live alone. The price is very affordable, more cost-effective than the water dispenser, and it also saves space.

    304 stainless steel precision pipe as a water outlet is equivalent to a "faucet", and direct contact with drinking water is very particular about the safety and hygiene of the material. 304 stainless steel is recognized as food-grade stainless steel by the country. The precipitation of heavy metals arsenic, cadmium, lead, chromium, and nickel meets strict standards.

    The pipe fittings are polished to remove the excess weld height of the inner pipe wall. The pipe wall can be polished into a mirror effect, which improves the rust resistance and scale resistance of the stainless steel pipe, and removes grease. It can reach the cleanliness required by food grade and can be used with confidence.

    The ductility of 304 stainless steel precision tube is δ5(%)≥40, hardness ≤201HBW, ≤92HRB, ≤210HV; it is not easy to break when bending, and can be bent to any angle. It has superior processing performance and greatly reduces the scrap rate. Cost savings.

    In addition, it is used as a heat exchange tube in a gas water heater, which is exposed to high temperature and humidity for a long time, and has strict requirements on corrosion resistance and high temperature resistance. 304 stainless steel is resistant to high temperatures of 800 degrees Celsius, and its thermal conductivity (W·m-1·K-1): (100°C) 16.3, (500°C) 21.5, is the best choice for heat exchange tubes for gas water heaters.

    304 stainless steel precision tube adopts bright solution annealing treatment to heat the steel tube at high temperature and quickly cool down, dissolve the carbide in the structure, improve the corrosion resistance of the tube, and extend the service life of the heat exchange tube.

    Precision polishing is used to improve the smoothness of the inner tube wall, make the tube wall corrosion-resistant, anti-scaling, and heat transfer; stainless steel is easy to cut to length and can be made into thin-walled tubes. In addition to improving heat transfer, it can also save costs , Performance and economy coexist.

    The above is the application of 304 stainless steel tube as direct contact with food and as heat exchange tube in the electrical industry. After detailed analysis of material properties and processing performance, we learned that 304 stainless steel precision tube can still be used in this way.
