En10305-2 Cold Drawn Precision Steel Tube Welded Carbon Steel Pipe

EN10305-2 E155,E195,E235,E275,E355 +C +LC +SR +A +N Cold Drawn Welded Precision Steel Tubes, is produced by cold drawing over mandrel and die on the ERW welded steel tube, to achieve better tolerance and good concentricity, both outside and inside weld seam is completely removed during the cold drawing process.

Production Process:
Cold rolling by Cold pilger machine and Cold rolling machine

Cold drawing by cold drawn machine
Size: 20-350mm

Please specifiy the final heat treatment when sending the enquiry.
