| No.3 | under 2mm ±0.15mm |
Note: For the finished seamless steel tubes the tolerances No.1 shall be applied.
The tolerances on the tube length shall be in the range of 0 to+50mm.However,when tolerances outside this range are especially required,agreement shall be made between the purchaser and manufacturer.
(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.
