There are many materials for seamless steel pipes, such as 20#seamless pipes and relatively common is these two types. What kind of distinguishing between spicy? Simply speaking, the foreign labels they choose to choose It is completely different, and other effects are completely different. For example, the second steel pipe is tightly used in an environment where it is winding, cold deformation and shaped, and the thickness of the time is relatively small. There is a harsh request, otherwise it will easily find a signs of cracks. In the ordinary environment, there will always be a higher request in the limited limit. The first seamless steel pipe is to tighten the high -pressure seamless steel pipe 20g of steaming booths with higher parameters. It is probably to be applied in the process of production of high pressure. It is probably in the gas pipe in the cold wall pipe, and if the seamless tube is used to do wall temperature, it should be at least less than 450 degrees. The probability is short and high, but many people are probably not inquiring. The a little characteristics of the steel pipe are tightly tightened. It really represents its characteristics. Thinking, it can reach the inevitable support result, and the load is also very energetic, so the broad benefits are in the fluid pipeline. After the expert’s certification seamless steel pipe, if the seamless tube is placed under the local appearance, after the large -scale car is crushed, it will not find any changes or any deformation signs. Therefore, it has become a very good selection of fluid pipelines. In the process of selection of the investment, everyone will also think that the Ning Shen is doubled. In our survival, its chances of discovery are relatively high.
