ABSTRACT:
A process for removing accumulated meltable matter from a pipe includes introducing inside a pipe a cylindrical travelling element or pig made of low density, high elasticity foam. A mixture of reagents which, after a certain period of time will cause a highly exothermic reaction to occur, is introduced inside the pig so that by displacing the pig the meltable deposits within the pipe will melt and will be carried by the pig to a place from which they will be removed together with the pig.
