Simple Pigging System With Drop Out

This video illustrates an Inline Services VIPRS pig running through a line where a pig receiver unit is present. Before the pig is placed in the line the valve has been closed so that no product is present behind the VIPRS pig.  As the pig moves through the line the inside of the pipe is cleaned and excess product is pushed through to the containment vessel. Once the pig triggers the magnetic pig senor and reaches the receiver unit, the unit is removed, or dropped-out of the line with the pig inside. The pig is removed from the receiver, then re  The process is repeated to achieve the desired result.
