Advantages of stainless steel pipes

Stainless steel classification: There are many types of stainless steel, with different uses and different production methods. The outer diameter of stainless steel pipes currently produced ranges from 0.1 to 4500mm, and the wall thickness ranges from 0.01 to 250mm. In order to distinguish their characteristics, steel pipes are usually divided into the following categories. Classification by production method Stainless steel pipes are divided into seamless pipes and welded pipes according to production methods. Seamless steel pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn pipes and cold-rolled pipes are Welded pipes for secondary processing of steel pipes include straight seam welded pipes, etc.
Classification by cross-sectional shape: Stainless steel pipes are divided into round pipes and special-shaped pipes according to cross-sectional shape. Special-shaped tubes include square tubes, rhombus tubes, elliptical tubes, hexagonal tubes, octagonal tubes and various asymmetrical cross-section tubes. Special-shaped tubes are widely used in various structures, hand tools, and mechanical parts. Compared with round pipes, special-shaped pipes generally have a larger moment of inertia and section modulus, which can save steel. Stainless steel pipes are divided into equal-section pipes and variable-section pipes according to their longitudinal cross-section shapes. Variable cross-section tubes include tapered tubes, step tubes, periodic cross-section tubes, etc.
Stainless steel pipes have very good performance in all aspects, so they can be used very well in many situations. They are also more stable because they have no cracks during actual use. Let’s take a look today. Its three major advantages.
1. It is more hygienic and reliable. There is no need to worry about the occurrence of red water, green water and other problems, and its impact resistance is very good. And the weight is relatively light, so it can be transported and constructed more easily, and its corrosion resistance and other properties can still be maintained within a certain range despite the lighter weight, and because the weight itself becomes lighter, The cost of processing has also been reduced.
2. Because stainless steel pipes will form a thin protective film on the surface. Although this protective film is very thin, it is very strong. Even if it is damaged, as long as there is oxygen next to the 304 stainless steel pipe. exists, then we can continue to regenerate to avoid rust, and we only need to understand the characteristics of stainless steel pipes and use them correctly. When the medium in the water pipe is less corrosive, it is generally not too You don’t need to worry about rust, and you don’t need to worry about some rusty protrusions appearing in the galvanized steel pipe, which will lead to a smaller inner diameter and increased resistance. You can get better results without clogging. water flow.
3. For example, in the actual construction site, due to the limitations of the construction site, it is necessary to consider the distortion factor between the pipe and pipe fitting connections.
We all know that stainless steel pipes have very good performance when used, and the reason why it can have such good performance is because the process used when it is used is relatively good. Today I will show you how Let’s take a look at the three major forging processes of steel pipes.
1. Die forging is generally a process used to make threaded tees, crosses, elbows and other small-sized pipe fittings. Because the shapes themselves are relatively complex, it is necessary to choose the die forging process for manufacturing. . The blanks used in die forging are all rolled profiles. Therefore, when we use stainless steel pipes as raw materials, we should first roll the steel ingots into bars or use them as die forging blanks after forging. This can also eliminate problems such as segregation and looseness in the steel ingots. . After the blank is heated, it is placed in the mold for forging, so that the pressure can allow the metal to flow and fill the mold cavity; if there is flash in the blank after die forging, the remaining flash material needs to be flushed away to complete the entire process. Die forging work.
2. Free forging can be used to manufacture some special-shaped pipe fittings or stainless steel pipes that are not suitable for processing by die forging. In free forging, the general shape of the pipe fitting, such as a tee, should generally be forged first.
3. Cutting processing: Some steel pipes with a cylindrical shape can be made by direct cutting of bars or thick-walled pipes. During processing, the fibers of metal materials generally flow basically parallel to the axial direction of the steel pipe. However, some tees, crosses, and elbows cannot be directly formed by bar cutting.
