Welded Carbon and Alloy Steel Tube Production Method:
DOM, ERW+ Cold Drawn
ID Honing + Roller Burnish+ Skiving
Appearance of Welded Carbon and Alloy Steel Tube:
The internal and external surface finish of the tubes is smooth, while the Weld Seam is somehow not visible or tangible.
The ID surface with roughness Ra≤4μm, the best ID smoothness we could reach Ra≤0.8μm
The inner surface can be measured and reported if this is requested by the purchaser before PO.
