Welded steel pipe according to different production process

In general, according to the different production process, we can category the welded steel pipe into several types. They are general welded steel pipe, like we said ERW steel pipe and so on; galvanized ERW steel pipe which is so familiar with us; oxygen welded tube which is not so common and so on. General welded steel pipe would use mild steel as raw material. Material would determine its function. So this kind of steel pipe can be used in low pressure fluid after the water pressure test, bending and other tests. Galvanized steel pipe would be a kind of steel pipe used for enhancing the corrosion resistance. It would be divide into hot dip galvanized pipe with thicken zinc layer and electrical-galvanized pipe with low cost. And for metric system welded tube and spiral welded tube, we would talk next time. You can contact us for details about them.
