Steel tubes - the use of tubes in industry is very wide.
Generally, from stainless steel balustrades and constructions, to gas pipelines or refinery pipelines, the scope of projects is much bigger than you can imagine. In the VIRGAMET's offer we have available:
| Standard description | Hot finished structural hollow sections of non-alloy and fine grain steel. |
| Manufacturing | Hollow sections should be manufactured as non-welded or welded sections. |
| Steel grades used | Non-alloy steel: S235JRH, S275JOH, S275J2H, S355JOH, S355J2H Fine grain steel: S275NH, S275NLH, S355NH, S355NLH, S460NH, S460NLH |
| Dimensions and tolerances | Outside diameter D +/- 1% with minimum +/- 0,5mm and maximum +/- 10 mm wall -10%/ upper deviation limit restricted by mass deviation Mass +/- 6 % |
| Pipe lengths | Any length between 4000 – 16000 with the maximum difference of 2000
per one order item Approximate length 4000 – 16000 +/- 500 Precise length 2000 – 6000 -0/+ 10mm More than 6000 -0/+ 15mm |
| Tightness | No requirement to conduct leak detection testing. |
| Tests | Mandatory requirements: ladle analysis tension testing resilience testing (wall area of 6mm) (J2, N, NL groups) external surface quality and dimensions. non-destructive joint testing. Optional requirements: check analysis ladle analysis: extended (non-alloy only) resilience testing (JR and JO) (non-alloy only) The maximum carbon equivalent content must be met. The material should be weldable The material should be suitable for galvanizing. Repair through welding (weld overlaying) on the section body is not permitted. |
