1. Introduction of stainless steel pipe Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. Stainless steel pipe is an economical type of steel. It is an important product of the iron and steel industry. Usually accounts for about 8%-16% of the total steel. It has a wide range of applications in the national economy. It is an economical profile of economical metal steel and an important part of high-efficiency steel, especially suitable for oil drilling, smelting and transportation industries. Geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing, boiler, medical equipment, furniture and bicycle manufacturing also require a large number of various stainless steel pipes. Due to its hollow section, stainless steel pipes are suitable for pipelines that transport liquids, gases and solids. At the same time, compared with the round steel of the same weight, the steel pipe has a larger section coefficient and higher resistance to bending and torsion, so it has become a variety of mechanical structures and building structures. Significant material on structures and components made of stainless steel tubing has a greater section modulus than solid components. 2. What are the advantages of stainless steel pipes?  1. The stainless steel pipe has excellent mechanical properties, super wear resistance, and a thin and dense chromium-rich oxide film on the surface, which makes the stainless steel pipe have good water resistance in water including soft water, even if it is buried underground. Corrosive substances are underground. It also has excellent corrosion resistance. Rusty steel pipes can withstand high-velocity water erosion up to 30 m/s. The diversion stainless steel pipes used in high-head power stations still have a service life of more than 100 years at the end of the nozzle with a water flow rate of more than 60m/s.  2. The tensile strength of stainless steel pipe is greater than 530N/mm, which is 2 times that of galvanized pipe, 3-4 times that of copper pipe, and 8-10 times that of PPR pipe. It has good ductility and toughness, which is conducive to saving water. Resource, beautiful, clean and fashionable appearance, 100% recyclable, good safety and hygiene performance, good temperature resistance, good thermal insulation performance, smooth inner wall, low water resistance, can work safely for a long time at -270℃-400℃, high temperature or No harmful substances will be precipitated at low temperature, and the material performance is quite stable.  3. The thermal insulation performance of stainless steel pipe is 24 times that of copper pipe, which reduces heat loss, is suitable for hot water transportation, does not cause environmental pollution, is green and environmentally friendly, and is conducive to sustainable development. Stainless steel scrap also has great economic value. Safe, non-toxic, non-corrosive, non-exuding, odorless, non-turbid, and no secondary pollution to water quality. Hospital Medical airtight Sliding Door The medical automatic door is a door that is generally installed in the operating room or the ICU ward for the medical staff to push in and out of the hospital bed. The medical automatic door has the function of inductive opening and safety anti-pinch. The medical staff only needs to extend the foot into the light control foot sensing box next to the entrance, and the door will automatically close.
After a period of time, the door will automatically close after the cart and medical staff have fully entered. If someone or a cart is next to the door leaf, the door will not close to provide a safe anti-pinch. In addition, the door frame of the medical automatic door is made of sealed profile, which has the characteristics of high air tightness; the light control foot sensing is adopted for the entrance and exit, so that the medical staff can open the door [without contact", which can effectively isolate the bacteria and personnel.
