The stainless steel plate bellows compensator is a kind of expansion element composed of winding, thick wall and transverse ripple composed of stainless steel bellows and prefabricated components. Its structure makes the stainless steel plate have the function of ductility, which can make the pipeline under many natural or artificial influences

Li, these businesses really want to put an end to it.

Granby.Stainless steel pipe is widely used in petrochemical industry, pipeline transportation and other working conditions with strong corrosive media due to its excellent corrosion resistance. The main reason why stainless steel pipes have corrosion resistance is that a large number of elements CrNi are added, and Cr determines the corrosion resistance of stainless steel pipes

Argon two processes. The back argon filling protection can be divided into two processes: solid core welding wire +tig process and solid core welding wire +tig+ water-soluble paper process; Back non argon filling protection is also divided into flux cored wire backing welding and welding rod (flux coated wire) backing TIG welding.

.CO2 welding what does CO2 welding mean? It is a gas shielded arc welding using carbon dioxide as the protective gas, which is fully called carbon dioxide gas shielded arc welding.

Significant. As for the combined welding of steel pipes with high-frequency preheating the weld quality is equivalent to the conventional argon arc welding and plasma welding. The welding operation is complex, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment,Granby304 stainless steel pipe price price per ton, with low investment cost and good benefits.

Principle of non torsion pipeline compensator: the non torsion pipeline compensator adopts Pascal basic theory of fluid dynamics, and the design structure appropriately uses the closed ring steam chamber. The steam chamber has two ring force surfaces, one is the fixed hole in the steam chamber, and the other is the closed telescopic pipe shoulder ring surface in the steam chamber

In engineering, the following methods are often used to prevent intergranular corrosion: reduce the amount of carbon in the steel, so that the amount of carbon in the steel is lower than the saturated solubility of austenite in the equilibrium state, fundamentally solve the problem of precipitation of chromium carbide (cr23c) on the grain boundary

The salt spray resistance test distinguishes the advantages and disadvantages of the salt spray resistance of the samples after different surface treatments. The differences of the pitting resistance and the resistance to corrosive media of the samples after different surface treatments are compared by the electrochemical test. The film thickness of the silicon film is indirectly characterized by the film weight test

φ Medium and low pressure transmission pipes above 159mm), and the specific application fields are: furnace pipe, material transmission pipe, heat exchanger pipe, etc.

Service first.Pipe,Granby304 seamless stainless steel pipe price, 904L stainless steel pipe and other brand products, complete designated products, quality assurance It eliminates the worries of users.

Why does the stainless steel plate bellows compensator use the technology of primary hydraulic press forming and mechanical equipment forming in the hot smoke compensator stainless steel plate bellows compensator, assisted by computer reliability design, production and manufacturing, with accurate specifications, and good commodity structure

It is a low-carbon high-alloy stainless steel. Because the nickel content in its composition is less than 4%, the steel contains ferrite austenite structure, so it is called duplex stainless steel. Generally speaking, duplex stainless steel has a good balance of alloy elements, including ferrite elements such as chromium and molybdenum, as well as austenite

Stainless steel pipes and water transmission equipment for water, gas and other fluids are advanced basic water purification materials in the world today. They have strong corrosion resistance, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.

Quality assurance.Different

Better metal.

Stainless steel plate is a kind of metal material with beautiful surface and good corrosion resistance, which can give full play to the inherent surface performance of stainless steel without surface treatment such as color plating; Of which; 304 stainless steel is mainly used for corrosion-resistant containers,Granby2507 stainless steel plate customized, tableware, furniture, railings

Granby.It is concluded that the corrosion resistance of duplex stainless steel is equivalent to that of 316L stainless steel, but the mechanical properties are better than 316L, the elongation is reasonable, and the cost is lower than that of 316L and 4462.

Chlorine ion exists in the service environment. Chloride ions exist widely, such as salt, sweat, soil sea breeze, floating rust of iron foam, etc. Stainless steel corrodes rapidly in the presence of chloride ions even more than ordinary low carbon steel. So the use of stainless steel

Solution treatment. After the steel is heated to 1050~1150 ℃ and then water quenched, the main purpose is to make the carbide dissolve 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 intercrystalline corrosion, solid solution treatment is usually adopted to make
