What Kinds of Materials for Seamless Steel Pipes?
The use of seamless steel pipes is more extensive, and the effect is better. So what kinds of materials of seamless steel pipes are there? Please follow us to see it together.
1. What kinds of materials are for seamless steel pipes?
There are many kinds of materials for seamless steel pipes. The following five kinds of materials of seamless steel pipes are common:
1. Common carbon structure
2. High quality carbon structure
3. Alloy steel
4. Stainless acid resistant steel
5. Low alloy steel
There is a hollow section for the seamless steel pipe. It can be used for fluid transport, such as gas, natural gas, water and so on. It has the strength of bending resistance and torsion resistance, which is also very good. Moreover, because the material of seamless steel pipes is not the same, the aspects of use are also different.
2. What should we pay attention to for the construction of seamless steel pipes?
In the process of welding seamless steel pipes, we should not use welded branch pipes, and there can be no weld in the bending position. It not only affects the aesthetic effect, but also is not conducive to long-term use. It is very easy to produce leakage.
We need to pay special attention to the welded junction of seamless steel pipes. It must be straight, and the weld should be in full. The surface of the weld shall not have burned through, cracking, nodulation, porosity and other defects. Otherwise, it will affect the later use and bring unnecessary troubles.
The welding wave of seamless steel pipes needs to be consistent. In the pipeline of the opposite dislocation error, we need to control about 20 percent of the wall thickness and within the scope of 2mm. If exceed this value, it will affect the later use.
In the process of welding, it is necessary to ensure that there will be no bending in the position of the welding joint, and there can be no wrong mouth. Another is the positioning of electric welding. We need to spot welding at four points. After straightening, the use of free conversion form needs to do welding work.
