What is stainless steel sanitary pipe

Jan 17,2022

I think we all know a lot about stainless steel, stainless steel sanitary pipe is a hollow oblong steel. Mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structure parts. The performance of stainless steel pipes varies depending on the material. So, let's understand what is stainless steel sanitary pipe together!
What is stainless steel sanitary pipe
It has changed the traditional water supply materials and connection methods, and can effectively solve the problem of secondary pollution of drinking water. The stainless steel sanitary pipe drinking water pipe and stainless steel pipe adopt the advanced German double-card crimping connection technology, which is known as "the green pipe of the 21st century".
Stainless steel pipe is a long steel with a hollow cross-section and no seams around. The technology of the product determines its limit performance, the lower the accuracy of the general seamless steel pipe. The thicker the wall thickness of the product, the more economical and practical, the thinner the wall thickness, the processing cost increases significantly, and its detection and shaping must be processed offline. 304 or 316L stainless steel pipe, sanitary steel pipe, stainless steel pipe (manufacturer, specification); Therefore, the wall thickness is uneven, the appearance of the tube is low, the cost of sizing is high, and there are pitting spots on the inner and outer surfaces, and the black spots are not easy to remove; In high pressure, high strength, mechanical structure materials show its superiority.
People mainly put forward requirements for the surface gloss, passivation layer and oil prohibition of stainless steel sanitary pipe: stainless steel sanitary pipe is mainly used in beverage, wine, biological engineering, food and other production equipment and pipelines.
1. Surface finish: mainly to prevent the fluid material moving in the tube from forming a wall in the tube, which is easy to be polluted after a period of time. The inner and outer surfaces of the stainless steel sanitary tube are ground to make the surface of the steel tube smoother. The so-called mirror. Blockages can also form inside the tube.
2. Passivation layer: after grinding, in order to achieve the anti-corrosion effect of steel pipe. The steel pipe needs to be immersed in the passivation tank, and the surface of the steel pipe is oxidized with acidic passivation solution to form a passivation layer.
3. Oil prohibition degree: oil prohibition cleaning is carried out after passivation is completed, mainly to prevent the oil pollution of the pipe wall itself from the fluid flowing in the pipe. Remove oil stains on the surface of the steel pipe. It needs to be checked with a grease analyzer after completion.
Features of stainless steel sanitary pipe
Most stainless steel sanitary pipe products are made of high-quality imported 304 stainless steel to ensure that the pipes are hygienic, non-toxic and non-polluting.
Stainless steel sanitary pipe as one of the widely used steel, no heat treatment hardening phenomenon (non-magnetic, the use of temperature -196~800). It can be used for household goods (one or two kinds of tableware, cabinets, indoor pipes, water heaters, boilers, bathtubs), auto parts, medical equipment, building materials, chemistry, food industry, agriculture, ship parts. 304L stainless steel sanitary pipe belongs to low-carbon Austrian stainless steel. 304 stainless steel sanitary pipe has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, and has good stamping, bending and hot workability. It also has certain anti-corrosion ability to alkali solution and most organic acids and inorganic acids. The steel is suitable for the manufacture of deep drawing parts, has general grain boundary corrosion resistance and excellent corrosion resistance and cold working stamping performance, has strong corrosion resistance to nitric acid and other oxidizing acids, and acid delivery pipes, acid storage containers, etc. 304H has good corrosion resistance and welding performance, and good heat resistance.
