  Nowadays, many people like to use stainless steel pipes in the whole process of applying pipelines. This is even more due to the corrosion resistance of stainless steel pipes. So what do you know about the corrosion resistance of stainless steel pipes? All metal materials react with the co2 in the air and produce an oxide film on the surface. The tragedy is that the iron oxide produced on ordinary carbon steel is oxidized again, which causes the rust to continue to develop and eventually produces holes. Can use paint Or oxidation-resistant metal materials (such as zinc, nickel and chromium) are electroplated to ensure the surface of carbon steel, but, as everyone knows, this type of maintenance is only a plastic film. If the thickness of the protective layer is reduced Destroyed, the steel underneath has just begun to rust.   The corrosion resistance of stainless steel industrial pipes lies in chromium, but because chromium is one of the components of steel, the maintenance ...

  ​Stainless steel pipes  have a lot of functions, which is the reason why stainless steel pipes are widely used. So what are the functions of stainless steel pipes? Let's take a look.   The corrosion resistance of stainless steel pipes depends on the alloying elements contained in the steel. Chromium is the fundamental element that makes the stainless steel tube corrosion resistant. When the chromium content in the steel reaches about 12%, the chromium and the oxygen in the corrosive medium form a very thin oxide film (self-passivation film) on the surface of the steel, which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements of stainless steel pipes include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the arrangement and function of stainless steel pipes.  　　   Stainless steel pipe is a hollow long round steel, which is widely used in pet...

Stainless steel plates   can be processed into many types of stainless steel products, and the application fields are becoming wider. Although the constituent elements of stainless steel plates are mostly the same, but stainless steel plates classification are different. Therefore, when purchasing stainless steel plates, you must be clear about the classification of stainless steel plates in order to find the stainless steel plates you need. Here are the common types of stainless steel plates on the market: 1. Classification by thickness: thin plate, medium plate, thick plate, extra thick plate 2. Classification by production method: hot rolled steel plate, cold rolled steel plate 3. Classified by surface characteristics: galvanized sheet (hot-dip galvanized sheet, electro-galvanized sheet), tin-plated sheet, composite steel sheet, color coated steel sheet 4. Classification by purpose: bridge steel plate, boiler steel plate, shipbuilding steel plate, armor steel plate, automobile s...

The  stainless steel plate  will be pasted with a protective film after processed. This film is to protect the surface of the board from scratches. We must pay attention when sticking film, to not damage the surface of the plate. So how to choose film, and what to take care? First, the common films are black and white film, blue film, transparent film, etc. The thickness is 5 to 7 filaments, and the viscosity ranges from low to high . Customers can choose according to their needs. Second, In terms of viscosity, generally snow sand should choose a higher viscosity film, while filaments can choose a lower viscosity film. The viscosity should be increased in winter and reduced in summer. It is to prevent those phenomenon: a. the film fall off when the viscosity is not enough. b. the film will be difficult to tear or even degumming if the viscosity is too large. Third, from the production process, the rubber particles in the film are difficult to avoid, but the rubber particles ha...

The use of   stainless steel pipes   is very extensive in our daily life. It plays different roles in different industries, maybe you will unfamiliar with it's usage in boiler, so let's focus on this knowledge. 1. Stainless steel pipes also have certain limitations. For example, round pipes are not as strong as square and rectangular pipes when flat bending. Agricultural machinery frameworks, steel and wood furniture, etc. use square and rectangular pipes. According to different purposes, special-shaped stainless steel pipes with different cross-sectional shapes are required. 2. Stainless steel high-pressure boiler pipes are mainly used to manufacture superheater pipes, reheater pipes, air guide pipes, main steam pipes, etc. of high-pressure and ultra-high pressure boilers. 3. Boiler pipes are mainly used to make water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arched brick pipes. HC...

 Although the longitudinal cracking phenomenon of  stainless steel seamless pipe  is a very serious problem and vary to seen, but it happened sometimes, and will make the pipe unusable. So, what causes this phenomenon? When the stainless steel seamless pipe has longitudinal cracking, the stainless steel pipe appears to penetrate the pipe wall longitudinally, which is sudden. Usually it occurs on the whole body of the stainless pipe, and sometimes occurs at the end of the hammer. Here are the reasons: 1. If the reduction in large, the degree of uneven deformation will increase, and the residual stress will increase. 2. There are too many consecutive drawing passes during the air drawing, and the steel pipe has a large residual stress and work hardening. 3. Improper annealing includes too low temperature, uneven temperature or too short time. 4. The pipe wall of the transition part after the hammer head is partially recessed too deep or the end of the stainless steel seamle...
