The choice of materials and use of stainless steel pipe

DataTime:[2016-10-4]
Many variable factors are expressed in terms of corrosive medium characteristics, namely, chemical products and its concentration and atmosphere, temperature, time, so if the media do not understand the nature right to the use of materials, material selection is difficult. However, the following can be used as a guide for selection:
304 stainless steel pipe is widely used material. In the building can withstand the corrosion, can be resistant to food processing etching medium (but containing concentrated sulfuric acid and chloride component of high temperature corrosion may occur), resistance to organic compounds, dyes and a wide range of various inorganic compounds. 304L pipe (low carbon), nitric acid resistance is good, and durable medium temperature and the concentration of sulfuric acid, widely used as a liquid gas tank, used as a low temperature (304n) equipment, appliances and other consumer products, kitchen equipment, hospital equipment, means of transport and waste water treatment device.
316 stainless steel pipe than the 304 stainless steel pipe containing a little more than nickel, and contain 2% to 3% of the molybdenum, corrosion resistance than the 304 pipe well, especially in the tendency to lead the starting point of corrosion of chloride medium. Has been developed for sulfite pulp machine of 316 stainless steel pipe, because it is durable sulfate compounds. Moreover, its use has been extended to deal with a lot of chemical products in the processing industry.
317 stainless steel pipe containing 4% to 3% of the molybdenum (in this series is also the higher level), and contains more than 316 stainless steel pipe, with a higher resistance to pitting corrosion and corrosion cracking performance.
430 stainless steel pipe than 304 stainless steel pipe alloy content is low, as in the moderate atmosphere of high polishing decorative use, also can be used as nitric acid and food processing equipment.
410 stainless steel pipe in the three general-purpose stainless steel with low alloy content, selects the need for strength and corrosion resistance with high load-bearing components such as nut firmware. Stainless steel pipe corrosion medium chemical products in the moderate atmosphere, water vapor and many in ease.
2205 duplex stainless steel pipe than 304 stainless steel pipe and 316 stainless steel pipe is superior, because he has a high resistance to chloride stress corrosion cracking, and has about two times the strength. But for domestic stainless steel pipe for 201 stainless steel and 304 stainless steel is the most commonly used.
