Abstract
Repair of borehole centrifugal pumps involves complete disassembly and removal of steel parts from a long steel casing made of thick-walled pipes. In this paper, the technology of removal of steel parts from the pipe using a pneumatic hammer with impactor portion 400 kg in weight at the compressed air flow rate not more than 3 cubic meters per minute is discussed.
