ASTM A513 1010 1020 DOM Steel Tube (DOM)Drawn Over Mandrel : The first stages of manufacturing : ERW ,but in the finishing stages : Entire flash weld is removed and the tube is clod drawn over a mandrel.which provides the tube with a better dimensional tolerances,good surface finish and the strongest weld strength achievable.ASTM A513 1010 1020 DOM Tube Size range: O.D.:6-350mm W.T.:1-12.5mm L:max12000mm Grade: 1010, 1020, 1026 Production: ERW + DOM Packing: In Hexagonal Bundles, with anti corrosion oil protection, with seaworthy packing dom TubingDeliver condition: 1.
