RE: Fouling of Pipes

Hello Pete

Usually, the pipes are in diameters of 3" up to 12", in lengths of upto 20 feet.
They are removed from the plant, placed on the ground in a safe place. Using diesel fuel blow torch, driven by compressed air, the flames and hot gases are directed into the pipe.
The steel pipe expands and most of the calcium based scale slouches off. The stubborn scale that remains in the pipe is hammered to dislodge it. Works like a charm.

Ahmed,
I am mostly a non-contibuting reader on this forum. I don't have a suggestion now, but I am very curious about the "burning " part of your calcium scale. If you could elaborate a little about that, I would appreciate it.
Thanks
Pete
