Intelligent Pigs or Smart Pigs are used to inspect and collect a variety of data about the condition of a pipeline, this is called an In-Line Inspection or ILI.
Examples of the data collected during an ILI are:
A clean pipeline surface is needed in order to run an intelligent pig, and imperative to the integrity of the data collected.
Making assumptions that the pipeline is clean, using the wrong type of pig, or not performing enough pre-cleaning pig runs, can be detrimental to the pigging program and lead to costly problems when running smart pigs, or needing to re-run the smart pig, which immediately eliminates any gains which may otherwise have been made.
The types of pigs used for pre ILI cleaning depends on a variety of factors including the type and size of line, product running through the line, the existing maintenance pigging program. An experience pigging expert, like our team at Inline Services, can design a pre ILI cleaning program to meet your specific needs.
Our team will review your historical pigging information and provide guidance to ensure optimal performance of your intelligent pigging program such as recommending the best type of pipeline pig and most effective run frequency of each pig to ensure effective cleaning of the internal pipeline surface.
Inline Services specializes in helping customers determine the most effective pre ILI cleaning and ongoing pigging maintenance programs for any application.

Simple Pigging System with Drop-Out
Simple Pigging System Closure
This animation demonstrates a simple pigging system closure. Inline’s VIPRS pig is positioned in the launcher as the product is run through the pipeline. At the end of the product run, the VIPRS pig is launched to remove all product from the line. The pig will trigger the indicator to alert that the pig has reached the end of the line.
Bi-Directional Pigging
This animation demonstrates Bi Directional Pigging. Inline’s VIPRS pig positioned in the launcher as product is run through the pipeline. At the end of the product run, the VIPRS pig is launched to remove all product from the line. When the VIPRS pig reaches the JB receiver, the propelling media is turned-off. When this happens the VIPRS pig is resting at the jail bar in the JB receiver; propellant is used on the receiver side of the pig to return it to the launcher.
Automated CIP System
This animation demonstrates a fully automated VIPRS bi directional pigging process system with CIP. Inline’s VIPRS pig is first positioned in the pig launcher. The product is pumped from the storage tank to the destination. The VIPRS pig is then launched to push the remaining product to the destination and captured in the VIPRS wash chamber at the destination station. Next, the CIP solution is pumped through the line to wash the chamber and pig. Finally, the pig pushes the CIP solution out of the piping and leaving the pig clean and ready for the next product run.
