The recrystallization temperature changes with the shape variable. When the shape variable is %, the recrystallization temperature drops to ℃, and the recrystallization annealing temperature of cold deformed austenitic stainless steel is ~ ℃. At ℃, it needs to be kept warm for h, fully burned at ℃, and then water-cooled.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.Chepo,　　— Ferritic stainless steel for decoration, such as automotive accessories. Good formability, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including , l, etc., with an outer diameter of about ￠ - ￠ and a wall thickness of about mm-mm (generally medium and low pressure transmission pipes with a specification of more than & phi; mm). The specific application fields are: furnace pipes, material transmission pipes heat exchanger pipes, etc.Pourham,Restate the quality of stainless steel pipe, such as stainless steel pipe, we promise & ldquo; chromium and nickel & rdquo; Penalty for false and provide quality inspection report and certificate of conformity.The petrochemical industry, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including,ChepoSus631 stainless steel belt, l, etc., with an outer diameter of about ￠ - ￠ and a wall thickness of about mm-mm (generally medium and low pressure transmission pipes with a specification of more than & phi; mm). The specific application fields are: furnace pipes, material transmission pipes, heat exchanger pipes, etc.The slab solidified on the surface continues to be rapidly cooled through the secondary cooling section until the core becomes solid, and the whole continuous casting process of stainless steel pipe fittings is completed.

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, the time for application has come.However, some people will still communicate online or by telephone to ask whether the stainless steel pipe we produce can be used as a water pipe.Good ductility, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.Quality risk,Chloride ions exist in the service environment. Chloride ions exist widely, 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.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr%Ni.;- Ferromagnetism due to m transformation shall be considered in use (such as in instrument parts).

The welding of stainless steel pipe is usually composed of backing welding, filling welding and cover welding. Backing welding of stainless steel pipe is a key link in stainless steel pipe welding, which is not only related to the quality of engineeringSales Department,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.Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x..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, 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,ChepoStainless steel plastic lined pipe, the colored film of stainless steel industrial pipe has more uniform surface color, good reproducibility, and significantly improved wear resistance and corrosion resistance.Chepo,W = (outer diameter wall thickness) & times; wall thickness & times; . = KGM (weight per meter).Continuous casting shall be adopted for stainless steel pipe fittings, and cooperate with out of furnace refining, which significantly improves the production efficiency, omits the blank opening process and saves a lot of energy consumption.Add a small amount of sulfur and phosphorus to make it easier to cut.
