On the application of stainless steel pipe plate of cold coagulation apparatus, to insist on the water leaks faster than 1.5m / s, so that fresh water minerals and other solids in the tube by least outdoor the convergence failure. For the disposal of salt of the bombard equipment is not rust steel framework, is devised with the best non-narrow gap combat use of thin-walled parts.
3. Soil
Buried soil in the metal,[link widoczny dla zalogowanych], and depends on the weather and other elements, alterations in period are in the great, complex situations. Theory confirmed the subsistence of mediocre austenitic stainless steel pipe excellent corrosion resistant properties of the taint a large minority, merely in the good 1Cr13 and 1Cr17 Yang Xiao and more punctual in the detriment to occur. 0 Cr 17Ni12Mзр2 Xiao Yang stainless steel capillary pipe in entire the experiments can complete resistance to pitting.
4. Nitric acid
Not less than 14% chromium iron sordid body austenitic stainless steel pipe and pipes have excellent resistance to nitric acid corrosion. 1Cr17 stainless steel nitric acid factory namely no commonly used along industrial equipment. However, because 0 Cr 18 Ni 9 is usually good for there is cross-shaped representation and welding representation,[link widoczny dla zalogowanych], fruit He is not in the use of a large number of replaced 1Cr17 stainless steel tube.
Other austenitic stainless steel capillary pipe corrosion resistance of nitric acid to take 0 Cr 18 Ni 9 period far. 1Cr17 stainless steel pipe is usually higher than 0 Cr 18 Ni 9 of the corrosion rate slightly faster and a higher degree of temperature and light sound of their greater clash.
If only the cold steel into the handle does not apply the warm iron nitrate ambition fight dirty body austenitic stainless steel intergranular corrosion occurred. Thus,[link widoczny dla zalogowanych], the accessible proper lukewarm disposition to prevent the type of corrosion category, perhaps using the kind of species-type corrosion-resistant stainless steel pipe.
5. Sulfuric acid
A
hough stainless steel pipe itself as "will not oxidize," but encountered the emulating while several or to cautious the medium.
1. Acidic water
Acidic water is leaching from the ore and coal are not the natural purification of water, because it is a muscular acid so its corrosive than fresh water from the natural strength have tiny to lose. As the water contained in sulfide ores and coal's role in leaching of acid water usually include a large number of shopping together sulfuric acid. He during which the water contains a small amount of ferric sulfate, the corrosion of carbon steel with a very large role.
Mongolia acidic water to do with the carbon steel equipment is usually very quick to be corrupt. The role of acidic water with Mongolia by the experimental results of assorted file denote namely Beijing satellite antenna installation, is the kind of environment austenitic stainless steel capillary pipe corrosion under not more function.
Austenitic stainless iron pipe in concentrated river water and mordant corrosion in great function, special non-corrosion movie aboard the barriers to greater heat conduction. Therefore, the usefulness of communication commonly accustomed in cold stainless steel capillary pipe.
2. Saline water
Salt water corrosion resistance specifics of surface erosion is constantly the situation presented. On the stainless steel pipe to a large level of water because of salt corrosion resistance incurred merely fast portion of the damaged layer. The corrosion of steel produced Punctuality additional cause is the erasure in the stainless steel tubes accompanied to myoga arranged on fresh inorganic medium and the repose of the light oxygen may constitute good power cell. Shaped failure overnight, these batteries are very active, and the formation of a large number of corrosion and surface erosion. Salinity water in the circumstance of high-speed nailed, such as sewage pump impeller, austenitic stainless steel capillary pipe width of pipe corrosion is usually always great.
