Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.Editor's note on the causes of steel rusting: chloride ions exist widely, such as salt, sweat stains, seawater sea breeze, soil, etc. stainless steel corrodes rapidly in the presence of chloride ions, even surpassing ordinary low-carbon steel. Chloride ions form complexes with Fe in alloy elements, reducing the positive potential of Fe, and then being stripped of electrons and oxidized [].Reed inkrisThe pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles, then slightly tighten the piece, and then rotate it for two circles until it is cut off. It must not be enough to allow personal strength to be in place at one time to lock the piece to cut off the pipe, otherwise the pipe end will be cut off, and the pipe fittings or rubber rings cannot be inserted; After the pipe above DN is cut, the internal and external burrs must be removed with a hand grinder, and an appropriate outer slope opening shall be opened at the same time to avoid damaging the sealing ring.Austenitic stainless steel has good resistance to uniform corrosion, but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content, intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix, which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.Franca,Raw materials -- strip splitting -- welded pipe making -- heat treatment -- Correction -- straightening -- end repair -- pickling -- Hydrostatic Test -- Inspection (spray printing) - packaging -- delivery (warehousing) (pipes for welded pipe industrial piping).When the addition of chromium reaches %, the atmospheric corrosion resistance of steel increases significantly, but when the chromium content is higher, it is not obvious. The reason is that when alloying steel with chromium, the type of surface oxide is changed to be similar to that formed on pure chromium metal. This tightly adhered chromium rich oxide protects the surface from further oxidation. This oxide layer is very thin. Through it you can see the natural luster of the steel surface, which makes the stainless steel have a unique surface. Moreover, if the surface layer is damaged, the steel surface will react with the atmosphere to repair itself, re form this passive film and continue its protective effect.Stainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.

At 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.Allowable depth of straight track: hot rolled and hot-rolled steel pipes with diameter less than or equal to mm shall not be greater than % of the nominal wall thickness, and the large depth shall not be greater than .mm; cold drawn (rolled) steel pipes shall not be greater than % of the nominal wall thickness, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.Installation works,Water preparation, storage, transportation, purification, regeneration,Reed inkris304 large diameter stainless steel pipe, seawater desalination and other water industry excellent materials. The demand is about tons.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.After that, the second widely used steel is mainly used in food industry,Reed inkris304 stainless steel pipe, pharmaceutical industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than stainless steel pipe, it is also used as & ldquo; marine steel & rdquo;. SS is usually used in nuclear fuel recovery devices. Grade stainless steel Steel pipes usually also meet this application level.

After molten steel casting, stainless steel pipe fittings generally adopt the same vertical, vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle the ladle to be poured is transferred above the tundish mouth through the rotary table, and then the molten steel is tundish through the long nozzle. The molten steel in tundish enters the mold through the submerged nozzle for forming, condensation and continuous downward movement.How many?,Good ductility,Reed inkrisStainless steel seamless welded pipe, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.Shop around and choose affordable stainless steel water supply pipes. Comparing the prices of pipes sold by various companies, we should choose carefully and should not buy them. However, the transmission energy consumption of stainless steel pipe water supply pipe is low, which saves the transmission cost, so the price will not be too expensive.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.Reed inkris,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)Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.The back is not protected by argon, and good economic benefits have been obtained.
