History and Information

Graphskill foam pigs were developed in the early 1980's to be used in clearing newly fabricated pipelines of debris prior to pipe lines being commissioned.

Their versatility was recognised for use with pipe welding as purge dams and another 'breed' of foam pig was developed.

Now Graphskill supply an extensive 'breed' of foam pig products to a vast range of industries for varied uses such as:

> Cleaning pipes of old product ready to accept new

> To dry pipes after washing

> To plug drilling equipment

> Retaining inert gas for welding operations

> Scrubbing and cleaning old pipes (reducing the need for complete replacement)

> As bungs to keep out dirst whilst pipes are not in use
