When pipeline is clean:

Original properties of pipeline are restored, back towards

parameters of Engineering & Design

Ri ht diti t d f i tiRight conditions are created for inspection

Mechanical Pigging

Removal of …. with mechanical pigsRemoval with pigs alone can be effective, however

risky and slow

Black powder & paraffin can stick and lodge pigs

Pigs pack solids into pits,causing errors in ILI

General 11

Oil & Gas Services

Mechanical Pigging

Good for removing free liquids

Breaks down particles to smallerBreaks down particles to smaller

particles

Smaller particles fill anomalies

Micro small particles cause downstreamMicro small particles cause downstream

nuisance problems
