Q:What factory uses industrial stainless steel tube to be more?
The electric power industry including nuclear power industry, the demand for stainless steel tube is large, the industry mainly uses the stainless steel seamless pipe, specific application fields: boiler pipes, water pipes, power tubes etc..According to the World Nuclear Association reports, China has 5 power stations under construction, 6 included in the plan, 19 are planning, it is estimated that power plant construction and maintenance of various types of stainless steel pipes each year about 25600 tons.
Q:310 stainless steel resistance to high temperature?
American brand 310S, also known as 2520, used in high temperature furnace tube manufacturingMain features: austenitic stainless steel
Q:Mechanical properties of stainless steel tubes
The phenomenon of deformation due to external forces increases with time is called creep. At a certain temperature, especially at high temperature, the greater the load, the faster the creep occurs. Under a certain load, the higher the temperature and the longer the time, the greater the possibility of creep. On the contrary, the lower the temperature and the slower the creep rate, the less creep is when the temperature is low to a certain temperature. This minimum temperature varies according to the type of steel. In general, pure iron is at about 330 degrees, while stainless steel has been strengthened by various measures, so the temperature is above 550.
Q:Disadvantages of stainless steel tubes
Galvanized iron pipe is the most widely used material at present. Because of the corrosion of galvanized iron pipe, the content of heavy metals in water is too high, which affects the health of human body.
Q:What is sanitary stainless steel pipe?
Surface finish: the pipe inside and outside surface polishing treatment, the pipe surface is bright; it is a mirror. We often say is mainly to prevent the tube away the fluid material formed within the tube wall, a long time is easy to pollute and formed pipe plug.
Q:How about stainless steel 2520 and 316?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. Uses: marine equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Q:Why can it stainless steel be put together with carbon steel tube?
Potential difference: the stainless steel pipe with a more positive potential and the carbon steel pipe with negative potential are even connected. The stainless steel tube is cathode, and the carbon steel tube is anode. The greater the potential difference between the two, the greater the galvanic corrosion tendency.
Q:How can the inner walls of stainless steel tubes be polished?
Electropolishing is thrown to the workpiece as anode, insoluble metal poles at the same time as the cathode, immersed into electrolytic cell, with the direct current produced anodic dissolution selectively, so as to achieve the surface brightness increasing effect. Specific can be used to search "what is electrolytic polishing" can understand!
Q:Why does the 304 stainless steel pipe leak?
Austenitic stainless steels are extremely sensitive to chloride ion and can occur in a very short time if the temperature and concentration are appropriate. Therefore, the relevant standards and specifications in the clear requirements for austenitic stainless steel pressure vessels for hydraulic pressure test, there are strict requirements on the chloride ion concentration of the water, and after the test to put water clean, dry. In order to avoid residual moisture in the chloride ion corrosion of stainless steel.
Q:How can galvanized steel pipe to be connected with stainless steel pipe?
Welding flanges respectively, with flange connection, but galvanized pipe according to specifications, dynamic welding after two times galvanized,
