Grit Blast Preparations of LP Rotor

Client

European Biomass Energy Supplier

Scope of Work

Mobilise to site to remove build up of heat scale and combustion contaminants from LP Rotor surfaces to leave a surface suitable for NDT.

Products

Abrasive: 120 Grade (0.10mm – 0.25mm) Garnet.

Substrate

Nickel based super alloy.

Method

A self contained KUE Blasting Unit was mobilised to site and situated adjacent to the work area.

Heavy duty reinforced rubber blast lines were coupled together and run from the KUE Blasting Unit to the contained framework housing the LP Rotor.

Concurrently, KUE extraction units were fitted adjacent therefore increasing the visibility and thus increasing the safety for all personnel within the working environment.

Dual shift working ensured a short downtime enabling NDT inspections to take place immediately following completion of the grit blasting operations and cleaning of the work area.
