What is carbon steel pipe?

carbon steel pipe

It is a kind of steel tube alloy, which is made of solid round steel or steel ingot as raw material, and then made into capillary by perforating process, and then made by hot rolling or cold drawing technology. The carbon steel pipe on the market is divided into three kinds according to the different carbon content, different types, its performance and use range are not the same, we should choose according to the actual use environment

How to distinguish the quality of steel pipe

1. observe in detail whether there is folding on the surface of the steel pipe, if there are many different lines on the surface of the steel pipe, it means that the product is inferior. If the manufacturer in the production process, in order to pursue production efficiency, choose to reduce the amount of material, it will lead to the broken line phenomenon when the steel pipe is rolled, and once the steel pipe is broken, it is prone to cracking when it is bent in the later period

2. observe in detail whether the surface of the steel pipe is pocked, if there is pocked surface on the surface of the steel pipe, it means that the product is inferior. The reason why the steel pipe is pocked is generally because the rolling groove is worn too seriously, resulting in irregular problems on the surface of the steel pipe. Many bad manufacturers in order to pursue interests, often appear the phenomenon of excessive rolling groove

3. observe in detail whether there are cracks on the surface of the steel pipe, if there are cracks on the surface of the steel pipe, it means that the product is inferior. The reason why the steel pipe cracks is generally because the manufacturer uses bad soil when producing the steel pipe, and the soil bad pores are generally more, and it is easy to crack during the cooling process, and when it is rolled, it will naturally leave cracks

4. observe in detail whether the surface of the steel pipe is scratched, if the manufacturer's production equipment is very simple, it is easy to appear burrs, scratch the surface of the steel pipe, if the surface of the steel pipe is deeply scratched, it will lead to the strength of the steel pipe is reduced, affecting the performance and service life of the steel pipe
