Since the 5th January we have been working to complete the repairs to a gas heat exchanger. The customer wanted the top 3m of the 76mm diameter tubes cut off and renewed, along with the tube plate in way. The photograph only shows half of the job that had 1,584 tubes in total, the same number of holes that had to be cut in the new tube sheet! All the tubes were screwed onto welded sockets made and fitted to the good remains of the old tubes. All carried out at the top of a cooling tower 30m up in the air, with only ladder access, exposed to the January weather.
Well done to the whole squad for a good job done safely.
