E355 DOM High precision tubing DOM steel tubing for
telescopic cylinders steel tubes
Size Range: OD: 6-329mm, WT: 1-15mm, Length: 5.8m/6m, maximal 11.8m
Standard:EN10305-2 Welded Precision Steel Tubes, is produced by cold drawing over mandrel
and die on the ERWwelded steel tube, to achieve better tolerance and good concentricity, both
outside and inside weld seamis completely removed during the cold drawing process.
Materials:E355 full aluminum killed fine grain practice.
Process:Welded, cold Drawn-Over-Mandrel (DOM), Stress Relieve Annealed (SRA; BK+S), round
precision tubing. The welded tube must be full body normalised in case of stretch reduction
after welding and prior to cold drawing. Otherwise only weld seam normalised is accepted.
