Decorative stainless steel pipe: usually the outer wall is relatively bright, so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe, the price also varies greatly. The general production process of decorative stainless steel pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product pipe stainless steel product pipe: generally, the surface of stainless steel product pipe is also a bright surface, and a small number of pipes with acid pickling industrial surface. As mentioned above, stainless steel product pipe belongs to the purpose of stainless steel products, because the outer diameter size, mechanical properties, acid, alkali and corrosion resistance of stainless steel pipe are relatively good, Therefore, stainless steel pipes are generally used as anti-corrosion materials or hardware products in large-scale production enterprises. The production process of stainless steel pipes is one-time forming, and nitrogen protection is also added during welding.Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series),The steady creep rate is usually used to evaluate the long-time creep performance of materials. For the application of long-life materials, the steady-state creep rate of stainless steel pipe under high temperature and stress is the key index of the material, and can be extrapolated. The following are the test results of stainless steel pipe under different test conditions. The results show that the steady-state creep rate of stainless steel pipe sample is in the order of magnitude after creep at ℃ (mpa ℃ (mpa) for h; when the temperature condition increases to ℃ (the stress decreases to MPa), the creep performance of stainless steel pipe sample is good, and creep fracture occurs. See for the change of steady-state creep rate of stainless steel pipe sample under several conditions. When the temperature increases, s creep deformation rate does not increase,Gibara5mm thick stainless steel plate, which shows little influence on the temperature and stress, and creep fracture occurs under this condition Compared with several other common structural materials,GibaraStainless steel hot and cold water pipe, it can be seen that the creep performance of several materials is better than that of ordinary materials under all test conditions. After hours of test, the total strain does not exceed .%. The curve is relatively stable and the fluctuation is small, indicating that the test data is stable and reliable. Stainless steel pipes are widely used because of their excellent corrosion resistance It is widely used in petrochemical industry, pipeline transportation and other working conditions with strong corrosive media. The main reason for the corrosion resistance of stainless steel pipes is the addition of a large number of elements CrNi, and Cr is the main element determining the corrosion resistance of stainless steel pipes. The electrode potential of stainless steel pipes jumps with the increase of Cr content. However, stainless steel pipes are in the subsequent heat treatment During the treatment, Cr element will precipitate into the matrix in the form of carbide. On the one hand, the hardness of Cr carbide is larger than that of the matrix and the service wear process can improve the wear resistance of stainless steel pipe. On the other hand, the precipitation of Cr containing carbide will lead to Cr Element dilution zone in some parts of the matrix, increase the number of batteries of the material, reduce the electrode potential of stainless steel pipe and reverse the corrosion Therefore, in order to obtain good corrosion and wear resistance the combination of mechanical properties and corrosion resistance of stainless steel pipe materials needs to be considered. At present, some scholars have studied the effects of austenitizing temperature and time, tempering temperature and time on the mechanical properties of stainless steel pipe by heat treatment to change the corrosion resistance of stainless steel pipe And corrosion resistance, it is found that austenitizing temperature can change mechanical properties, but has little effect on corrosion performance, while tempering temperature has a great effect on the corrosion resistance of materials. Appropriate austenitizing temperature and tempering temperature can improve the corrosion and wear resistance of materials. Some scholars use surface treatment to improve the corrosion and wear resistance of materials, It is concluded that low-temperature nitriding forms a diffusion layer on the surface of the material, improves the wear resistance of the material, interacts with Cr and chemically stable phase -fen to improve the corrosion resistance of the material.When improved, it is possible to use it in refrigeration related engineering. Recently, suslx (cr Ti, Nb LC) and susl have been applied to frozen shells. Ferritic stainless steel has body centered cubic structure. When the material properties become weaker, sharp cracks will expand rapidly and cause brittleness. Austenitic series stainless steel will not produce brittleness because it has face centered cubic structure. Austrian stainless steel SUSL (cr-ni LC) and SUSL (cr-ni-mo-lc) shows that it still has superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement due to sensitized carbide or & sigma; equal heterogeneous precipitation.Mangen, and the front weld is protected by argon, slag and alloy elements.Model & mdash; The addition of sulfur improves the processability of the material.The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag,GibaraWide cold rolled stainless steel strip, which can improve the yield of %, save energy and shorten the production cycle, so as to improve the yield of molten steel.

Meet the needs of architects and structural designers.The stainless steel strip is supplied in coils, also known as strip steel. It is divided into hot rolling and cold rolling, as well as ordinary steel strip and high-quality steel strip. There are many kinds of stainless steel belts! Wide use! There are: stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt, J stainless steel belt, S stainless steel belt, L stainless steel belt, L stainless steel belt, S stainless steel belt, stainless steel iron belt, etc! Thickness: .mm-mm, width: mm-mm, can be customized without standard!The back side is not protected by argon, and the flux coated welding wire (self protective flux cored welding wire) + TIG process is adopted. In the s, the backing welding wire has been developed. Recently, China has also developed the stainless steel backing welding wire (i.e. flux coated welding wire, such as tgftgftgftgf, etc.) It has been applied to the actual construction and achieved good results. We have successfully applied it in the capacity expansion and reconstruction project of Urumqi Petrochemical.Where is good,The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion days after it is replaced with stainless steel.Stainless steel seamless steel pipe for structure (instead of gbt-)

Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.Inspection environment, and argon gas is not used inside the weld. The welder's operation is simple and fastFor the length of welding arc, ~ mm is better for ordinary steel welding, and ~ mm is better for stainless steel welding. If it is too long the protection effect is not good.For more than years, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as the Chrysler Building in New York City. However, in many other applications, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.Gibara,Combined steel and spring steel such as CrMnTi simn, the proportion of water pipes is very small, whether it is data consumption or price. However, once the water pipes show achievements, the results will be very serious. Therefore, it is extremely important to choose water pipes with reliable quality high volatility, convenient maintenance health and environmental protection. With the development of the national economy and the progress of people's living standards, people's requirements for domestic water pay more and more attention to health and environmental protection. A good water source escort pipeline has become a careful choice.
