The shortcoming of the internal scab of the hot continuous-rolled seamless steel pipe is that there are dents similar to the size of soybean grains on the inner surface of the seamless steel pipe, and most of the scabs contain dark red or dark gray dirt. The influencing factors of internal scab are: metal oxide removal agent, gasifier processing technology, mandrel lubrication and other factors. Below is a look at how to manipulate the inner surface layer of seamless steel pipe with the seamless steel pipe manufacturer's network editor:

Thick-walled seamless pipes have been widely used in pipelines in recent years. In pipeline applications, due to the transportation of a large number of relatively high-viscosity liquids, its wear resistance is reflected. What are the characteristics of the wear resistance of the seam pipe?1. Wear r
