2022-07-28 11:41:19At present, stainless steel backing is divided into two processes: back argon filling and non argon filling. Back argon filling protection can be divided into solid wire + TIG process and solid wire + TIG + water-soluble paper process; The back non argon filling protection is also divided into flux cored wire backing welding and welding rod (flux coated wire) backing TIG welding.(V) the profitability of the steel plant has declined month by month. In the first half of , the metallurgical industry realized a profit of . billion yuan,ManzanilloPrice of 316L stainless steel pipe, a year-on-year increase of %, of which the ferrous metal smelting and rolling processing industry realized a profit of . billion yuan, a year-on-year increase of %. From January to may, the profitability of key large and medium-sized iron and steel enterprises was far lower than the overall level of the industry, and showed a downward trend month by month. Although the profit increased by %, it was only . billion yuan, with a profit margin of .%. In May, key large and medium-sized iron and steel enterprises realized a profit of only million yuan, falling month on month for five consecutive months, of which suffered losses, with a loss surface of %.The operators are mainly plumbers and argon arc welders with the cooperation of other types of work, and the argon arc welder shall have the certificate issued by relevant departments.Direct material,Stainless steel is usually divided into stainless steel pipe,ManzanilloTitanium mirror stainless steel plate, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel.Design and research of high precision stainless steel pipe stainless steel pipe has many advantages, 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 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, 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 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 cutting characteristics of the intermittent stainless steel pipe cutter in the cutting process are analyzed, and the cutting force in the cutting process is calculated. Secondly, the overall cutting scheme of the intermittent stainless steel pipe cutter is determined, and the structure is designed. Then, the finite element analysis is carried out for the important parts of the intermittent stainless steel pipe cutter, The reliability of its strength and stiffness is verified. In the design process of intermittent stainless steel pipe cutting machine the combination of theoretical analysis and computer simulation is used to verify the feasibility of the design, complete the tasks of scheme determination theoretical analysis and structural design, and verify the rationality of the structure. This paper aims to design a pipe cutting machine with high automation, compact structure and high cutting precision, so as to improve the cutting quality of stainless steel pipe and bring more economic and social benefits to the enterprise. This paper comprehensively analyzes the research on stainless steel pipe cutting machines at home and abroad, draws lessons from the advanced structural design of relevant foreign pipe cutting machines, and based on the structure of the existing planetary pipe cutting machine, A planetary double symmetrical eccentric installation intermittent cutting is proposed. The cutting can not only realize its own main motion and feed motion, but also reduce the deformation of stainless steel pipe in the cutting process. Professional L stainless steel pipe, s stainless steel pipe and L stainless steel pipe have large quantity, excellent quality and low price, fire resistance, water resistance, high temperature resistance, safe and reliable, and improve the quality of cutting surface.Brinell hardness in stainless steel pipe standards, and the hardness of the material is often expressed by indentation diameter, it is not suitable for steel pipes with hard or thin steel.
Stainless steel pipe, which was produced and used in China at the end of the s, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Quality recommendation,Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure,ManzanilloStainless steel tape magnetic, in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.In the past few years, the United States has imposed anti-dumping and countervailing duties on a variety of steel pipe products exported from China, including ring welded pipe, rectangular pipe pipeline pipe, welded stainless steel pressure pipe, oil well pipe and seamless steel pipe. These foreign double back pressures have greatly reduced the number of steel pipes exported by China.In engineering, the following methods are often used to prevent intergranular corrosion: reduce the amount of carbon in steel so that the amount of carbon in steel is lower than the saturated solubility of austenite in equilibrium, that is, fundamentally solve the problem of precipitation of chromium carbide (crc) on the grain boundary. Generally, the requirement of intergranular corrosion resistance can be met when the amount of carbon in steel is reduced to less than .%.Manzanillo,Brinell hardness in stainless steel pipe standards, Brinell hardness is widely used, and the hardness of the material is often expressed by indentation diameter, which is intuitive and convenient. However, it is not suitable for steel pipes with hard or thin steel.Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.
