Steel Extraction Flange For The Tyne Tunnel

Last week we received an order to produce a steel extraction flange for a company repairing the fume extraction unit at the Tyne tunnel.

There was one issue with this .. it was 1.7 metres in diameter! Larger than the standard on-shelf sheet size of 2.5m x 1.25m or 3m x 1.5m for 6mm thick steel. We do have a 4m x 2m waterjet bed though, so even though laser cutting would normally be faster (and therefore, more economical) for 6mm thick steel. We quoted to waterjet cut it from a bought in 4m x 2m 6mm thick steel sheet.

When installed, this part will connect extraction vents from the surface to the tunnel, keeping exhaust fumes from building up and keeping it’s users safe.
