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.

 

Main Date

Material: E355

Other material aviable: E235

Standard: EN10305-2

Technique: Cold Drawn

Od:6-80

Wt:0.5-10

 

Delivery Condition

 +C No heat treatment after the final cold drawing process

 +LC After the final heat treatment there is a suitable drawing pass
 +SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
 +A After the final cold drawing process the tubes are annealed in a controlled atmosphere
 +N After the final cold drawing operation the tubes are normalized in a controlled atmosphere

 

 

Advantage (compare with seamless cold drawn tube)

Better shape

Improved quality surface

Tight Excentricity and wall thickness tolerances

Good toughness at low temperature

USA Market: 90% of the cylinder in the USA market are produced with welded tubes

Cost fix Lengths More Cheaper
