Precision antibacterial stainless steel pipe is a kind of pipe fitting that has higher quality requirements than conventional pipe fittings. This high-quality requirement is mainly reflected in dimensional accuracy, pipe orifice roundness, pressure resistance, etc. This type of pipe is classified by pipe wall thickness, pipe orifice size, pipe cross-sectional shape and material, and the type of pipe directly affects use.
1. Pipe wall thickness
According to the wall thickness, it can be divided into thin-walled pipes and thick-walled pipes. The ratio of wall thickness to outer diameter of thin-walled pipes is less than 6%. The thinner the pipe wall, the better the heat dissipation performance. It can generally be used as a heat exchange pipe. The inner pipe wall It is required to be smooth and not easy to scale; suitable for central air conditioners, boilers, refrigerators, etc. The ratio of wall thickness to outer diameter of thick-walled stainless steel pipes is greater than or equal to 6%, and the welds must be completely penetrated. They have good pressure resistance, mechanical properties, abrasion resistance, etc., and can be used for textile equipment, electroplating Equipment, parts and components of dyeing equipment.
2. Nozzle size
According to the size of the pipe opening, it can be divided into small diameter and large diameter precision pipes. The diameter of small-diameter pipes is between 0.7~8mm. It has good corrosion resistance and tensile strength, and has very strict control over the pipe mouth error. It is mostly used in optical scale lines, thermal instruments and automation instruments; large-diameter pipes Pipes are generally used for fluid transportation. In addition to the requirements for the smoothness of the inner pipe wall, bright solid solution and pickling passivation are also required to improve the corrosion resistance of the pipe. They are mostly used in industrial pipelines, nuclear energy, electric power and sewage treatment equipment. middle.
3. Pipe cross-sectional shape
According to the cross-sectional shape, it can be divided into round tubes, square tubes and special-shaped tubes. Round tubes and square tubes are very commonly used, and can be used in drinking fountain outlet pipes, water purification equipment filter cartridges, lighting parts, etc. Most people don’t know much about special-shaped precision stainless steel tubes, which can be divided into fan-shaped tubes and triangular tubes. , elliptical tubes, grooved tubes…can be used for bathroom shower rack fittings, faucet tubes, gas water heater heat exchange tubes, mechanical equipment structural tubes, etc.; special-shaped tubes have very high precision on the nozzles, and once the deviation is too large, post-processing will be impossible Processing and installation.
4. Material
The more common materials are 304 antibacterial stainless steel and 316 antibacterial stainless steel, which are corrosion-resistant, safe and healthy, so they are widely used in bathroom, food, chemical and other industries. 310S stainless steel contains high percentage of chromium and nickel elements, has creep strength and can continue to work at high temperatures; 321 precision stainless steel pipe has high temperature stress breaking performance, high temperature resistance to creep degeneration and resistance to grain boundary corrosion. These two pipes with special properties can be used in high-temperature chemicals, steelmaking equipment, petroleum industry equipment, heat exchangers and boiler pressure vessels.
The above are the specific uses of different types of precision antibacterial stainless steel pipes, which can cover electrical appliances, bathrooms, food, industry, etc. Different uses can be customized and produced according to needs.
