At the same time, the Ministry of construction attaches great importance to the application of stainless steel pipes. The industry standard of stainless steel water pipe was issued and implemented in . The Ministry of construction has issued documents on relevant technical specifications and installation sets of pipeline engineering, which are being prepared by Tongji University. All kinds of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are qualified. Welcome to telephone inquiry and sincerely invite cooperation! At present, there are stainless steel pipes in Sichuan, Guangdong, Zhejiang, Jiangsu and other places, and the products have become mature. Therefore, the time for application has come.The best way to improve the quality of stainless steel pipe fittings is to change the process from ingot to billet. Due to the improvement of continuous casting process, this has become a necessary means to improve product quality.Monte-Carlo,　　— Ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Penticton,In many construction sites, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties. Therefore, careful and skilled welders should be selected for this work.Marking: in order to make the steel pipe complete the socket of the pipe fitting the length must be marked and marked at the pipe end.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.

Stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing the wall thickness and lowering the grid, so as to facilitate further development. In particular, the price of stainless steel pipe is not high, so the supporting connection, the reliability and price of pipe fittings are the main factors determining its development. Domestic developers have independently developed connection technology and pipe fittings in Sichuan, Guangdong, Zhejiang, Jiangsu and other places, which is a promising pipe. The Ministry of construction and relevant departments also attach great importance to this new type of pipe. According to China technology market management promotion center and gksz [] No. document on Application & ldquo; High diameter to wall ratio and high precision stainless steel medium and high pressure water supply pipes and supporting fittings and special technology & rdquo; It is learned from the notice that the application of stainless steel pipe technology and product is of great significance to improve the grade of modern buildings in China and improve and ensure the water quality of water supply.For example,Monte-CarloStainless steel strip, if the actual thickness of stainless steel round pipe is ., the weight of a single -meter-long stainless steel pipe is (-... = kg, and the theoretical weight of a -meter-long round pipe is .. For example, the weight of a single -meter-long stainless steel pipe of stainless steel square pipe with a thickness of . is [( + --... = kg). If the weight of stainless steel pipe per meter is calculated, the length can be changed into one meter.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, and nitrogen protection is also added during welding.Recommendation and consultation,Water preparation storage, regeneration purification transportation, such as high strength, good corrosion resistance, strong impact resistance and so on, which makes it widely used in various fields of life. With the continuous improvement of automation people have higher and higher requirements for the cutting quality of stainless steel pipe. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision, high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, and it is also the inevitable trend of the further development of China's industry. Firstly, the intermittent cutting method of planetary bisymmetric eccentric installation can reduce the cutting deformation of stainless steel pipe and improve the cutting accuracy; Secondly, the tool of the intermittent stainless steel pipe cutting machine is eccentrically installed on the planetary gear to complete the rotation at the same time of revolution. Therefore, only one main motor can drive two tools to rotate. The mechanical structure reduces the use of the motor, improves the use efficiency of the motor and reduces the manufacturing cost of the equipment; Then the main components of the intermittent pipe cutter are analyzed by using SolidWorks D solid software and ANSYS finite element analysis software. ANSYS software verifies the rationality of the structure and improves the service life of the pipe cutter. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development.

The product quality advantages of continuous casting billet of stainless steel pipe fittings are mainly reflected in that the non grinding rate of the outer surface of the billet except the head and tail section has reached more than %, and the total surface grinding yield has reached %. In order to achieve this goal, it is necessary to refine the molten steel, achieve low oxygen and sulfur content, do a good job in the metallurgy of the ladle and tundish,Monte-CarloStainless steel 904L plate, accurately determine the molten steel temperature, and realize no oxidation casting, Further reduce the inclusion content.Test results,Model & mdash; Add a small amount of sulfur and phosphorus to make it easier to cut.　　— The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.Refining and transportation industries are in great demand. Secondly, geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing, furniture and bicycle manufacturing also need a large number of various steel pipes. With the development of new technologies such as atomic energy medical equipment, rocket, missile and aerospace industry, stainless steel pipe plays an increasingly important role in national defense industry, science and technology and economic construction.Monte-Carlo,Typical ferritic stainless steels are Crl, Cr and Cr.Low temperature embrittlement of stainless steel pipe --- in low temperature environment, the deformation energy is small. In low temperature environment, the phenomenon of reduced elongation and area shrinkage is called low temperature embrittlement. It is mostly produced on the body centered cubic structure of ferrite series.At low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, while austenitic stainless steel or nickel base alloy does not show low-temperature brittleness. Sus (Cr) and SUS (cr) of ferritic stainless steel pipe It shows that the impact value decreases sharply at low temperature. Therefore, high purification process can be considered. With the help of C and N level, the embrittlement temperature is in the range of - ℃ to - ℃
