In the case of pickling, the seamless steel pipe has a stripping effect on the iron oxide scale, and also diffuses into the interior of the steel billet matrix and accumulates at the impurities or por...

Heat treatment of seamless steel tubes is a process for improving the properties of metal materials and their products. Depending on the purpose, the material and its workpiece are heated to a suitabl...

The thick-walled seamless pipe cold extrusion technology has the following advantages: 1. Extrusion parts size accurate surface smoothness: At present, the cold extrusion parts developed in China gen...

Generally, stainless steel seamless pipes are subjected to a pickling passivation process. In order to make the surface texture better and the appearance is more clean and beautiful, there is a key st...

In the anti-corrosion construction process of oil and gas pipelines, the surface treatment of seamless steel pipe is one of the key factors determining the service life of pipeline anti-corrosion. It ...

With the application of precision steel pipes, precision seamless steel pipes have high precision and have very good comprehensive performance. Therefore, after heat treatment, it can be applied to ma...

Galvanized seamless pipes are pided into hot-dip galvanizing and cold-galvanizing. The hot-dip galvanized steel tube is obtained by reacting a molten metal with an iron matrix to produce an alloy laye...

Hot-rolled tube blanks in cold-drawn seamless steel tubes may have defects such as cracks. At the same time, the resulting cylinders may break during use and deform, generally brittle fractures. There...

The application of thick-walled seamless steel pipes in pipelines in recent years is very large, and it can be said that there are huge applications. In pipeline applications, because of the large amo...
