“We were trying to pull out a 30ton tube bundle off a steam generator for repair. To our surprise, we only managed to pull 12in of length before the bundle puller gave in. We even used two hydraulic spreaders 50tons each but still failed. The problem costed us 6 days of delay. Losing hope, we tried to contact AHT for an out-of-the box solution. Overnight, Neil and Don told us they knew what the problem was and provided us a detailed procedure on how to pull out the bundle. They even gave us the design faults they have experienced with these kinds of heat exchangers so we can correct them.”
