seamless steel pipe,welded steel pipe,abter steel,china steel

Mar 30, 2020Metallographic method is one of the main methods to distinguish welded steel pipe from seamless steel pipe. High frequency resistance welded steel pipe does not add welding material, so the weld of welded steel pipe is very narrow, if the method of rough grinding and corrosion is adopted, the weld can not be clearly seen. Once the high frequency resistance welded steel pipe is welded and octagonal welded steel pipe, octagonal welded steel pipe high frequency welded tube 3pe coatedOctagonal Steel Pipe/Tube 1.Size:specified dimension 2.Surface:galvanized,paint,annealed etc. 3.Section:octagon,hexagon,ellipse,other profile pipe/tube special shaped steel pipe/tube custom profile steel hollow section special section steel pipes/tubes thickness:0.5-20mm OD:20-600mm custom design & demension special design & demensions can be customized,please send letter with attaching your high frequency welded tube 3pe coatedWhat is EFW steel pipe - pipelinedubaiHigh-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating.
