Heidelberg201 stainless steel plate squareWhat misunderstandings should be avoided in maintenance

The deformation and leveling of stainless steel plate are as follows: extension hammering; Cooling and cold striking method; Smothering method.

Folding editing the principle of this paragraph when the steel or sample is stretched, when the stress exceeds the limit, even if the stress is no longer increased, the steel or sample continues to undergo obvious plastic deformation, which is called yield, and the small stress value when the yield phenomenon occurs is the yield point. Let PS be flexure

Heidelberg.Organic substances (such as melons and vegetables, noodle soup, phlegm, etc.) adhered to the surface of stainless steel constitute organic acids in the presence of water and oxygen. For a long time, organic acids will corrode the metal surface.

It is well known that the stainless steel plate bellows compensator is actually quite different from the torsion free tube compensator. The root cause of this difference is that

.When transporting stainless steel plates the products shall be fixed in the carriage to prevent the products from colliding with each other or other sharp objects during transportation, resulting in pits on the surface of the plates, which will not only affect the use, but also affect the appearance.

Carbon steel pipe and stainless steel pipe are classified by material, while seamless steel pipe is classified by forming method. As the name suggests, carbon steel pipes are made of carbon steel, drawing and rolling, and a few are forming, among which drawing, rolling

Flux coated welding wire is used for backing welding and argon gas is not used inside the weld. The welder is easy and fast to operate, and has the characteristics of low cost. At the same time, it can also well ensure the welding quality (in the capacity expansion and reconstruction project of Urumqi petrochemical, we use this method to weld 28 junctions and repair junctions,

The general production process of the pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product tubes stainless steel product tubes: generally, the surface of stainless steel product tubes is also a bright surface, and a small number of tubes will have acid pickling industrial surface. As mentioned above, stainless steel product tubes are used for stainless steel products

The stainless steel surface contains acid, alkali and salt substances (such as alkali water and lime water splashing on the decoration wall), causing local corrosion.

The production mode is divided into seamless pipe and welded pipe. Seamless steel pipe can be divided into hot rolled pipe, cold drawn pipe and pipe, etc. cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Welcome to inquire.Equipment manufacturing and maintenance consume more than 20000 tons of stainless steel pipes. Sanitary or grade stainless steel pipes are mainly used in such industries. The sanitary seamless pipe made of imported sus30316l can meet the special requirements of various media in food and biopharmaceutical fields. Stainless steel fittings

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.

The formed iron oxide continues to oxidize,Heidelberg304 stainless steel plate 1.5 THK square, so that the corrosion continues to expand and eventually forms holes. Paint or oxidation resistant metals (e.g., zinc, nickel and chromium) can be used to

The basic principle of installation and the total area of the movable annular force bearing surface of the stainless steel plate corrugated compensator are exactly the same as the cross-sectional area of the expansion pipe. When the pipe compensator works, under the effect of material pressure,Heidelberg321 stainless steel coil,Heidelberg4mm stainless steel roll, the working pressure of the annular surface and the cross-sectional area of the expansion pipe is

middleman.In general, the alloy elements of duplex stainless steel are well balanced, which contains ferrite elements such as chromium and molybdenum, and austenite elements such as nickel and manganese. 4362 duplex stainless steel plate can be used to replace 316L and tensile strength: about 700 yield strength: about 350 elongation: About

Low temperature embrittlement --- in low temperature environment, the deformation energy is small. In low temperature environment, the phenomenon that elongation and reduction of area decrease is called low temperature embrittlement. Most of them are produced on the body centered cubic structure of ferrite series.

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.

Heidelberg.Stress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel. Austenitic stainless steels are prone to stress corrosion in corrosive media containing chloride ions. When

Steel pipes are made of steel billets of acid and heat resistant grades through heating, perforation, sizing, hot rolling and cutting.

In general, the
