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, 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.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Intibuca, — Add a small amount of sulfur and phosphorus to make it easier to cut.Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.Xingang,Duplex stainless steel product description: This stainless steel has good corrosion resistance in urea carbamate solution and high stress corrosion cracking resistance in chloride environment. At the same time, the duplex stainless steel has excellent mechanical properties and can be used in plant construction with high safety requirements.Stress relief treatment. Stress relief treatment is a heat treatment process to eliminate the residual stress of steel after cold working or welding. It is generally heated to ~ ℃ for tempering. For steels without stabilizing elements Ti and Nb, the heating temperature shall not exceed ℃, so as to avoid intergranular corrosion caused by chromium carbide precipitation. For cold worked and welded parts of ultra-low carbon and stainless steel containing Ti and Nb, they need to be heated at ~ ℃ and then cooled slowly to eliminate stress (the upper limit temperature is taken for eliminating welding stress) which can reduce the tendency of intergranular corrosion and improve the stress corrosion resistance of steel.Application fields: chemical industry, construction industry.
When the stainless steel fixed port is welded, how to ensure the argon filling protection on the inner side of the weld has become a difficult problem. For a long time, facing the national high price, the reasonable price and perfect service of all kinds of stainless steel plates,Intibuca310S stainless steel welded pipe, stainless steel coils, stainless steel belts and stainless steel pipes have been recognized by the majority of customers. In the actual construction on site, we use two welding joints The above problems were successfully solved by plugging with water-soluble paper on the side, ventilation from the weld center and sealing with adhesive tape on the outside (see Table ).Stainless welded pipe (grade y) gb- stainless cold plate (grade I)The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling which is connected by special thread for important threading pipe). For some special pipes, in order to make up for the impact of thread on the strength of pipe end, the pipe end is usually thickened before threading (inner thickening, outer thickening or inner and outer thickening).Quality assurance,The protection mechanism of stainless steel backing wire + TIG process is that the back weld is protected by the metallurgical reaction of slag produced by welding wire melting and its alloy elements and the front weld is protected by argon, slag and alloy elements.Design and research of high precision stainless steel pipe stainless steel pipe has many advantages, such as high strength,IntibucaStainless steel cooling pipe, 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, recently, the research on pipe cutting machine with high precision, high automation, 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.

Among the important pressure parts of ultra (supercritical) boiler, superheater and reheater are the parts with high working temperature and bad working environment. Previously, all such materials used in China were imported from abroad, while only steel material manufacturers in the world have limited capacity. Such materials have a large gap, expensive import prices, difficult procurement and short supply, which seriously affected the production of ultra supercritical boilers and the development of electric energy in China. At present, China's demand for utility boiler tubes is about tons, and with the continuous improvement of ultra (supercritical) power generation technology, the demand is expanding. Several large domestic enterprises have invested a lot of human and financial resources in the R & D and production of such products, and have made considerable achievements. On the one hand, it has made its own contribution to the development of national electric power industry, but also brought considerable economic benefits to enterprises.Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware, kitchen, water heater, water dispenser, etc. Some foreign businessmen also test the corrosion resistance of products: use NaCl aqueous solution to warm to boiling.
