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, 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.Ferritic and martensitic stainless steels are represented by series numbers. Ferritic stainless steel is marked with and ,Geel304 stainless steel round pipe, martensitic stainless steel is marked with and C, dual phase (austenite ferrite).Geel,In the building water supply pipe system, since the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. The professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have advanced technology, strict testing more affordable price and more preferential treatment. Welcome to consult. However, there are still some deficiencies in various pipes to varying degrees, It is far from fully meeting the needs of water supply pipeline system and national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the standard requirements.Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.Bako,Application: utility boiler industry, mainly in key parts such as high temperature section of superheater and reheater.Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.This material without titanium and niobium has an inherent tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust free

Model & mdash; other properties are similar except that the risk of weld corrosion is reduced due to the addition of titanium.Cold rolled steel strip for deep drawing is a low-carbon high-quality carbon structural steel cold-rolled steel strip for deep drawing complex drawing parts.In many construction sites, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties. Therefore,Model & mdash; The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.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.There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection modes have different application ranges according to their principles, but most of them are easy to install, firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber, nitrile rubber and EPDM that meet the requirements of national standards. L stainless steel pipe, s stainless steel pipe, L stainless steel pipe and other brand products are provided for a long time. The designated products are complete and the quality is guaranteed, which eliminates the need for use

There shall be a special storage rack. The storage rack shall be a wooden or painted carbon steel support or padded with rubber pad to isolate it from carbon steel and other metal materials. During storage, the storage position shall be convenient for lifting and absolutely isolated from other data storage areas. Protective measures shall be taken to avoid purification, collision with other components, purification and damage of iron metal.where, the maintenance of stainless steel pipe should be strengthened in each process of consumption mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.Surface treatment difference: surface treatment is usually divided into polishing, and the cost is about yuan and meter. If it is thrown into the lens barrel, the cost per ton will increase by yuan.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 .%.Geel,Geel302 stainless steel strip,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.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.In many construction sites, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties. Therefore, careful and skilled welders should be selected for this work.
