Hot-dip galvanized steel pipe: reacts a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pi...

Seamless steel pipes and welded pipes are mainly formed by different molding processes. Ordinary steel pipes, such as tap water pipes, are usually welded by bending the flat plate. You can find a weld...

A spiral welded steel pipe is a steel pipe which is welded and formed by a steel strip or a steel plate to be deformed into a circular shape or a square shape and has a joint on the surface. According...

The seamless steel pipe is a hollow section steel. The hollow pipe means that the steel pipe is hollow. It is for this reason that the seamless pipe is used in a large amount in transportation, and th...

First of all, the stainless steel seamless steel pipe is processed and hardened in the form of cold working at the time of production. For example, when it is bent, it has an opposite nature, that is,...

1. Cold-rolled steel allows partial buckling of the section, so that the bearing capacity of the bar after buckling can be fully utilized; and the hot-rolled steel does not allow local buckling of the...

In recent years, the demand for steel products by automobile and real estate enterprises has been large, which has greatly increased the demand for steel products, which has driven the development of ...

The steel pipe is pided into two major categories according to the molding method and the manufacturing method. The seamless steel pipe and the welded pipe (the welded pipe is what you call the seamed...

The seamless steel tubes that are common in our lives are round-tube type. So, do you know what it is used in our lives? When it comes to the use of seamless steel pipes, we are most familiar with th...
