Pigging is a process that enables product regaining after it has been transferred through pipes. The “pig” cleans the pipeline enabling maximum product recovery after each production cycle. The pigging process lets these, often undervalued, leftovers to be recycled and reused.
As an example:
DN 50: 2 litres per meter
DN 80: 5 litres per meter
DN 100: 8 litres per meter
DN 150: 18 litres per meter
DN 300: 80 litres per meter
Pigging installations have the following benefits:
After the pigging process the pipeline is free of the product:
This significantly reduces the usage of cleaning solutions. Product dumping is nearly eliminated and the cost of re-processing very low. The pipeline requires less cleaning time in the CIP cycle which effects in higher efficiency.
Piping line optimization
The Piping line is often dedicated to only one product. Pigging system enables transferring different products through the same line without the concern of mixing the products.
-one pipeline for different paint colours
-one pipeline for different types of wine
Production stoppage reduction
Pigging systems are the prefect tool for SMED (Single Minute Exchange of Die) projects. The time of moving from current product to the next one is significantly reduced through shortening or even eliminating the CIP process.
By adding all benefits (reduction of wastewater, increase of efficiency, pipeline usage optimization and stoppage time reduction) we achieve a very high ROI (return on investment).
