FREQUENTLY ASKED QUESTIONS
What is Pigging / Product Recovery System?
In simple words, the pig is an object which is propelled through the pipeline. The pig dimension is larger than the ID of the pipeline.
What is the objective of installing a Pigging / Product Recovery System?
» The main objective of Pigging System in product recovery.
» It also helps in cleaning the internal diameter of a pipeline at regular intervals.
» It enables multi-product transfer.
» Quick changeovers can be achieved.
» Reduces Contamination.
Which industries incorporate the Pigging / Product Recovery System in their process?
The technology of pigging is applicable to all industries whose process includes liquid transfers in pipelines.
Can high viscous liquids be pigged?
Paints, Cement, Grease, Oil etc. for industrial and Shampoo, Conditioner, Cream, Toothpaste etc. for Cosmetics and Soft Drink, Jam, Butter, Mayonnaise, Peanut Butter, Ice cream for Food and Beverages are easy piggable.
Can Pigging be incorporated into an existing plant?
Since the technology of pigging is greatly supported by the internal diameter and surface of the pipeline, it is important that the pipe and pipe fittings are designed to be piggable. Special highly polished pipes, Bends, Tees, Stoppers etc. are required to incorporate a Pigging System.
How does the Pigging logic work?

Is Pigging System compatible with CIP (Clean In Pace)?
IUS Pigging Systems are designed for overall compatibility with CIP.
Are there different types of Pigging Systems?
Since the design of a system is done as per the different processes of our customers, there are various tailored designs for inlet and outlets and automated, manual and semi-automated systems.
Are Launchers and Receivers required to use pig?
Launchers and receivers provide the easiest form for using a pig as per the design of a pig. They help a pig to perform properly. A pig is designed in such a way that the outer diameter (OD) of the pig is larger than the internal diameter (ID) of the pipe; this design standard makes it very difficult to manually insert a pig into a pipe.
What is the optimal speed of a pig?
The optimum speed for a pig is approximately 3 to 5 feet per second.
How much pressure is required for the pigging process?
We cannot exactly give a pressure range. The reason for this is because there are too many variables, including pig type, the OD of the pig, product type, product viscosity, temperature, build-up quantity etc.
