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?

IUS Pigging Systems enables us to create a wide range of logic as demanded by our customer’s manufacturing process. A cost-effective and precise logic is created to suit our customer’s process needs.

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.

What is a pigging system and how does it work?

A pigging system involves using devices known as “pigs” to recover product and clean pipelines on a regular basis from inside the pipeline. The pig travels through the pipeline, propelled by the product flow or by pressure, performing cleaning, and product recovery.

Are pigging systems environmentally friendly?

Yes, pigging systems are environmentally friendly because it reduces the need for chemical cleaning agents. It also reduces wastage and thereby minimizes the environmental impact by recovering products that would otherwise be lost and unrecovered.

What maintenance is required for pigging systems?

Regular maintenance includes inspecting and cleaning pigs, checking launcher and receiver equipment, and ensuring the pipeline is free of obstructions. Routine inspections and replacements of worn parts are also necessary.

What safety measures should be in place when using a pigging system?

Though the pigging system is fail safe, safety measures include proper training for operators, use of protective equipment, regular inspections, adherence to operational procedures, and emergency response plans. Ensuring the system is designed to handle the specific pressures and materials of your pipeline is also crucial.

How do I get started with implementing a pigging system in my pipeline?

Start by consulting with a pigging system provider to assess your needs and pipeline specifications. They will help design a system tailored to your requirements, provide the necessary equipment, and offer training for your staff on proper operation and maintenance.

Is pigging safe for use with food products?

Yes, pigging systems designed for the food industry use materials and components that comply with food safety regulations and standards, ensuring they are safe for use with consumable products.

What are the hygiene standards for pigging systems in the food industry?

Pigging systems for the food industry must meet stringent hygiene standards such as those set by the FSSAI, FDA or the European Food Safety Authority (EFSA). This includes using food-grade materials and ensuring easy cleaning and sanitization of the equipment. Pigging systems for the food industry must meet stringent hygiene standards such as those set by the FSSAI, FDA or the European Food Safety Authority (EFSA). This includes using food-grade materials and ensuring easy cleaning and sanitization of the equipment.

How does pigging reduce waste in the paint industry?

In the paint manufacturing process the pipelines are long and due to this there is a lot of hold up in the pipeline after every batch manufacturing. Pigging helps to recover residual paint from the pipeline, which can be reused or packaged, significantly reducing wastage. This also helps in reducing the environmental impact of paint production.

What maintenance is required for pigging systems used in the paint industry?

Regular maintenance includes cleaning and inspecting the pigs, checking the launcher and receiver mechanisms, and ensuring that the pipeline remains free from obstructions or buildup. Routine checks and replacements of worn parts is also necessary to maintain optimal performance.

Can pigging systems be automated?

Yes, many modern pigging systems can be fully automated, including the launching and receiving of pigs. Automation enhances efficiency and reduces manual labor.
