Stainless steel precision tube, also known as stainless steel high-precision tube, is a new type of precision tube with super corrosion resistance, high precision tolerance, excellent mechanical properties, etc. It is mainly used in chemical industry, electronics, machinery, precision instruments, etc. industry manufacturing. Therefore, the stainless steel precision tube standard must not only meet the quality requirements of the industry, but also meet the performance and use requirements of users.
Standard classification of stainless steel precision tubes
1. Standard types of stainless steel precision tubes: According to different material content, they can be divided into 200 series, 300 series, 400 series, 500 series, etc., of which 400 series is the best quality type.
2. Definition of stainless steel precision tube standards: Stainless steel precision tube standards include various requirements such as inner diameter, outer diameter, thickness, material, and surface.
Standard requirements for stainless steel precision tubes
1. Inner diameter: The inner diameter of stainless steel precision tubes must be processed by high-precision wire drawing, and the tolerance should be strictly controlled within 0.02mm to ensure high-precision results.
2. Outer diameter: The outer diameter of stainless steel precision tubes should be round, smooth and free of burrs, and the tolerance should be less than or equal to 0.1mm.
3. Thickness: As long as the thickness of the stainless steel precision tube meets the customer's requirements, there is no mandatory regulation, generally between 0.3-20mm.
4. Material: The stainless steel precision tube is mainly made of high-quality 304 or 316 stainless steel, and different materials can also be used according to customer requirements.
5. Surface: The surface of the stainless steel precision tube can be polished or frosted, or even a mirror surface.
Standard testing of stainless steel precision tubes
1. Visual inspection: Professional technicians use visual observation or a test tube inner and outer diameter measuring instrument to visually inspect the surface, inner diameter, outer diameter, thickness, etc. of stainless steel precision tubes. If any defects are found, they should be dealt with in time.
2. Chemical composition test: analyze various elemental compositions in the stainless steel precision tube material, and compare with the composition stated in the standard to ensure the quality of the material.
3. Mechanical performance test: professional technicians pass the mechanical performance test to ensure that the strength, ductility and hardness of the stainless steel precision tube meet the standard requirements.
the advantages of stainless steel precision tube standard
1. High precision: the tolerance range of stainless steel precision tubes can be as small as 0.02mm, which can better guarantee the high precision requirements of manufacturing.
2. Corrosion resistance: The stainless steel precision tube is mainly made of high-quality 304 and 316 stainless steel, which has super corrosion resistance and can withstand the erosion of various corrosive media for a long time.
3. Strong mechanical properties: Stainless steel precision tubes have the characteristics of high hardness, high ductility, high strength, etc., and are suitable for various complex mechanical structural parts.
5. Energy saving and environmental protection: the stainless steel precision tube adopts a production process with low energy consumption and a production method with low consumption materials, which greatly reduces the waste of energy and is more environmentally friendly.
The stainless steel precision tube standard is an important guarantee for the quality of the material and the effect of the user. If the existing standard can be properly applied in combination with the characteristics of the industry, it will not only ensure a higher quality product, but also improve the cost performance of the product and bring better benefits to the user. experience.
