Soluble Pigs can be used in systems where retrieval of the pig may be an issue, such as systems with no successful pigging history, or systems that are not equipped with pig retrievers. • Oil soluble pigs are used in hydrocarbon-liquid systems (condensate or oil).
They are constructed of hydrocarbonwax and are designed to dissolve in the condensate or oil.
• Water soluble pigs are used in wet gas (provided that there is sufficient free water), high water-cut oil, or water systems.
In both cases, solubility and life in the pipeline will be dependent on temperatures and fluid characteristics. Soluble pigs are available in ball or cylindrical shape to suit your application.
