　　Because ordinary seamless pipes have poor antioxidant properties. If such pipes are placed outdoors directly, it will give seamless pipes the best conditions for rusting. Because the seamless pipe rusts very quickly under normal temperature and oxygen environment. If it rains from time to time, the pipe will rust quickly. Because of this kind of pipeline, it has very superior oxidation resistance. Even if the API 5L PSL2 Carbon Steel Seamless Pipe for Oil And Gas is placed in the open air environment, the pipe will not rust. It's easy to bring about some usage problems. In terms of hardness and compressive strength, it has certain advantages. But just a few years ago, many industries that used seamless pipes did not take seamless pipes as the main piping material. Why? This is because seamless pipes have many advantages, but also have a very obvious disadvantage. That is the ordinary seamless pipe, for the use of the environment, there are certain requirements.

　　If seamless steel pipe is used, there is no need to worry about such a problem, because seamless steel pipe ensures the torsional strength of the pipeline. The reason why seamless steel pipe has such ability is that in the manufacturing technology, it has a certain gap with ordinary seamless steel pipe. Ordinary seamless steel pipe, in the process of production, will only experience a rolling, or there is no such process. The seamless pipe made in this way will have relatively weak torsional strength. As long as such pipeline undergoes some complicated processing, there will be some bad deformation. But unlike seamless steel pipes, the production of such pipes requires many times of rolling.
