Abstract
An apparatus is described, especially suitable for pipeline maintenance, able to sandblast the pipes making up the line which have had the outer protective layer removed by brushing (or similar operation). The sandblasting operation is performed by a mechanism which straddles a pipe of the line and is able to move along the pipe at constant velocity, comprising a pivoting element which carries a plurality of sandblasting nozzles at equal spacings; said nozzles receive the mixture of sand and compressed air from a physically distinct unit, comprising at least one compressor and one sandblaster; the two units are connected together by means of pipes or other means of flexible connection. Preferably, the mechanism comprises the motors necessary to make the unit move and to pivot the oscillating element. <IMAGE>
