Many people who engage in construction industry are concerned about a kind of main raw material that is welded steel pipe. Nowadays, this pipes occupy majority part of the steel pipe market and the widely application scope makes it more and more popular. Its main properties are good quality, high hardness, heavy load as well as corrosion resista...

There are many different types of steel which require different types of welding tools and techniques, assuming it can be welded in the first place. Low carbon steel is most suitable for spot welding. High carbon content and alloy steels tend to form hard welds that are brittle and could crack, though this tendency can be reduced by tempering. W...

In the early stage of steel pipe production, butt-welding is one common manufacturing method adopted for carbon steel pipe. At that time and even a long time, the butt-welding process was one quite elementary processing method in that it merely rolled a piece of heated steel plate into pipe form and created a longitudinal weld through compressio...

There are different types of welded steel pipe and it can be divided into general welded pipe, galvanized welded pipe, oxygen blowing metric welded pipe, welded steel pipe, wire casing, electric welding thin wall pipe, spiral welded pipe and so on. Now we will talk about something about these specifications. General welded pipe is often used for...
