Hmm, a kas ir oriģinālais termins, kas te tulkots? Scrubber? Tas tiešām ir inteligent pig, varu apliecināt, man te tādi netālu mētājas navalom.

Pigs get their name from the squealing sound they make while travelling through a pipeline.
Also 'PIG' is an acronym or backronym derived from the initial letters of the term 'Pipeline Inspection Gauge' or possibly 'Pipeline Inspection Gizmo' or 'Pipeline Internal Geometry' or 'Pipeline Inspection Gadget'.
