Stainless steel pipes have low strength and hardness and are not suitable for equipment or components that bear heavier loads and have higher requirements for hardness and wear resistance. Especially under the condition that multiple factors such as corrosion, wear and external load exist at the same time, the result of the interaction will significantly accelerate the material process and shorten the service life of stainless steel pipes. The content described in “The quality of stainless steel pipes can be inspected from many aspects” was carefully prepared by our editor for everyone. Do you still remember what was said in the previous article? These may be somewhat incomplete, and we will explain them one by one in future articles. I hope that through the introduction of this article, you can have a certain understanding of the quality of stainless steel pipes, which can be inspected from many aspects.
The quality of stainless steel pipes can be examined from many aspects, so when choosing a good stainless steel pipe, you must pay attention to how to distinguish the quality of stainless steel pipes. The steel strips of refining furnace stainless steel pipes are made from ores and other materials with refined furnace coal. It has ideal control of harmful raw materials. The material is soft, well polished, and the welds are smooth. The most important thing is that it has strong corrosion resistance, deep processing, and pipe bending. Convenient for deep processing such as welding. The steel strips of intermediate frequency furnace stainless steel pipes are poor in both material and production technology. The composition control is not easy to control, and it is also very serious for the environment. In addition, the polishing effect is poor, the hardness is high and deep processing is difficult, and most importantly, the performance is unstable and the corrosion resistance is poor.
Stainless steel plates rely on the formation of an extremely thin, strong, fine, and stable chromium-rich oxide film (protective film) on their surface to prevent oxygen atoms from continuing to penetrate and oxidize, thereby gaining the ability to resist rust. Once for some reason, this When the film is exposed to constant stress, the oxygen atoms in the air or liquid will continue to separate out, forming loose iron oxide, and the metal surface will be constantly corroded. How to bend stainless steel seamless pipe into a U shape? Some users In the process of using stainless steel seamless pipes, it is necessary to bend them into a U shape. If you follow the standard method, you must have specific operating mechanical tools, otherwise it is unlikely to get a good bending effect. Before starting work, we must understand the basic situation of stainless steel seamless pipes. For example, you need to know the relationship between the size and loading method of stainless steel seamless pipes.
Assume that there are three situations: 1. The diameter of the round tube is equal to the side length of the square tube, and the wall thickness is the same; 2. Both tubes are simply supported; 3. The loading method is the transverse concentrated force at the midpoint, and the polar inertia of the round tube If the moment is small, the deflection of the round tube will be large and the bending deformation of the round tube will be large. It is worth thinking about how we deal with this situation. If the ordinary stainless steel seamless pipe is bent without mechanical assistance, a similar method will be used: the stainless steel seamless pipe is filled with sand and then bent. To be honest, the bent stainless steel seamless pipe is very thin and does not have a machine. With assistance, the probability of success is really small. It is recommended that customers go to a stainless steel industrial seamless pipe manufacturer for processing. Stainless steel seamless pipe manufacturers generally have these machines, or you can buy the finished products directly from the manufacturer. The price should not be much different.
