Hardness test: annealed stainless steel pipes with inner diameter of more than mm and wall thickness of less than mm can be tested by w-b Vickers hardness tester which is very fast and simple, and is suitable for rapid and nondestructive qualification test of stainless steel pipes. For stainless steel pipes with inner diameter of more than mm and wall thickness of more than mm, Rockwell hardness tester shall be used to test HRC hardness. Stainless steel pipes For stainless steel pipes with inner diameter greater than mm and wall thickness less than mm, the special Rockwell hardness tester for pipes shall be used to test hrt hardness. When the inner diameter of stainless steel pipes is greater than mm, the Rockwell or surface Rockwell hardness tester can also be used to test the hardness of pipes.Model & mdash; Cheap model (British and American), is ferritic stainless steel (chromium steel).Jagodina,Before connecting the pipe fittings, mark the depth on the pipe first,Jagodina305 stainless steel square tube, so as to prevent it from being inserted in place and stuck.Solution treatment. The main purpose of water quenching after heating the steel to ~ ℃ is to dissolve the carbide in austenite and keep this state to room temperature, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion, solid solution treatment is usually used to dissolve CrC in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.Pilga,Assembly: the sealing ring shall be correctly installed in the U-groove of the pipe fitting, put the pipe into the socket of the pipe fitting and wait for crimping.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)

Assembly: the sealing ring shall be correctly installed in the U-groove of the pipe fitting, put the pipe into the socket of the pipe fitting and wait for crimping.For the manual clamping tool, the upper and lower jaw are fixed modules, and the pressure is set to output a constant pressure of MPa. The detection standard is to observe the seam of the upper and lower jaw and press it once or twice.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 .%.Welcome to inquire,Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor 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.Stainless steel has been used as a structural material for building new buildings and repairing historic sites for more than years. Early designs were calculated according to basic principles. Today, such as ANSI as of the American Society of civil engineers, are used

W = (outer diameter wall thickness) & times; wall thickness & times; . = KGM (weight per meter).new product,Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Hot dip galvanized sheet hot dip galvanized sheet, which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process, that is,JagodinaStainless steel necked pipe, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. Liaocheng Suntory stainless steel plate weighing method: stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel basic weight (density)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.Jagodina,High frequency welding high frequency welding: with relatively high power supply, it can reach a higher welding speed for steel pipes with different materials, outer diameter and wall thickness. Compared with argon arc welding, it is more than ten times its high welding speed. Therefore, stainless steel pipes for common use have a higher consumption rate. Due to the high speed of high frequency welding, it is difficult to remove burrs in welded pipes. At present high frequency welding Welded stainless steel pipe can not be borne by chemical and nuclear industries, with slightly higher carbon content which is also one of the reasons. & mdash; high strength cutting tool steel, and the hardness can reach hrc. It is one of the hard stainless steels. A common application example is & ldquo; shaving blade & rdquo;. There are three common models: C and f (easy processing type).Using CrO and hsoho as the main components and adding an appropriate amount of mnso.ho coloring solution, the chemical coloring of stainless steel industrial pipe was carried out. The effects of pretreatment process, coloring solution temperature, mass concentration and coloring time on the color film of stainless steel industrial pipe were discussed. Through a large number of experiments, a good formula and process range of coloring solution are obtained. With the increase of temperature and time, the film thickness increases, and the color changes are brown, blue, gold, purplish red and green. After curing and sealing treatment, the colored film of stainless steel industrial pipe has more uniform surface color, good reproducibility, and significantly improved wear resistance and corrosion resistance.
