EN10305-2 E355 OD10 Welded Steel Pipe Powerful Welding Strength For Hydraulic System
Description:
Cold drawn welded pipe, it is the production of one of the best choice of the multistage hydraulic cylinder tube, its process and precision seamless steel tube cold drawing process, is to use precision resistance welding (ERW) precision drawing, manufacturing the EN 10305-2 eu mechanical cold drawn steel tube welding standard.
Process:
After welding of resistance welded pipe, the overall pipe body passes through the positive fire to ensure that the weld and heat affected zone are in the same quality as the other parts in the metallographic structure and mechanical properties; Cold drawing and subsequent heat treatment (eliminating internal stress) and steel pipe have good size and mechanical properties.
Main Date:
| Material: | E355 |
| Standard: | EN10305-2 |
| Delivery Condition: | +C, +LC, +SR, +N, +A |
| Size Range: | Outer Diameter:φ6-φ80 Wall Thickness: 0.5-10 |
| Application: | High Precision Steel Tube is Widely Used in Automotive Part, Hydraulic System, High-precsion Machining. |
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.
Advantage (compare with seamless cold drawn tube):
1.Better shape
2.Improved quality surface
3.Tight Excentricity and wall thickness tolerances
4.Good toughness at low temperature
5.USA Market: 90% of the cylinder in the USA market are produced with welded tubes
6.Cost fix Lengths More Cheaper
