Primarily Flexicast pigs are used as separation pigs, displacement pigs or batching pigs. They are maintenance free and disposable so are often the preferred pig for cleaning and batching when mandrel or metal bodied pigs would not be suitable due to the construction of the line or where a number of short radius bends are in close proximity to each other.
Flexicast pigs are usually used in smaller sized pipelines up to 16” and are particularly useful in flexible rises as special variants can be made to accommodate dual diameters due to the internal diameter [i/d] change of the carcass of the riser and topside pipework. IPP Flexicast pigs can also be supplied with magnetic detection systems for topside or subsea tracking and location. They are not heavy and perform well in pipelines which are generally small in diameter, short in length, particularly when used in process plant pipework systems, tank farm pipework systems and are also useful for flooding and dewatering of small diameter lines during pre-commissioning. They are a very versatile tool and useful for a large number of applications.
