On site repairs are not the most desirable because testing, following the repair is not always possible until the equipment is up and running again , but sometimes we must go with the flow.
This unit was not possible to be decommissioned for repair without astronomical expense because of the size of the unit and its location , but fortunately only the return bends had been damaged upon installing into its new location , if it had been the headers which were damaged it would have been a whole different ball game.
Always ready to help where possible
