Exploring pipeline pigging techniques and how Ice Pigging can be utilised

Types Of Pigging

Pipeline pigging, a critical maintenance practice in many different industries, involves the use of devices called pigs to clean, inspect, and maintain pipelines. Various pigging techniques exist, each tailored to specific pipework conditions and maintenance requirements.

Understanding Pipeline Pigging

Pipeline pigging is a versatile process employed in various industries to ensure the efficient and safe operation of pipework. Pigs, which come in different shapes and sizes, are inserted into the pipeline and pushed through by the flow of the product or an external propellant. The primary types of pipeline pigging include cleaning pigs, batching pigs, and inspection pigs.

  1. Cleaning pigs: Cleaning pigs are designed to remove debris, sediment, and deposits that accumulate in pipelines over time. Nivalis's innovative Ice Pigging technique uses ice as the "pig". These pigs ensure thorough removal of contaminants to maintain optimal pipeline efficiency.
  2. Batching pigs: Batching pigs are used to separate different products within the pipeline, preventing cross-contamination. These pigs are particularly valuable in pipelines that transport multiple products sequentially.
  3. Inspection pigs: Inspection pigs, equipped with advanced sensors and cameras, play a crucial role in assessing the integrity of pipelines. They detect anomalies, corrosion, and structural issues, enabling operators to proactively address potential problems and prevent costly failures.

Ice Pigging – An Innovative Technique

Among the various pigging techniques, Ice Pigging stands out as a revolutionary method that combines the principles of traditional pigging with the unique properties of ice. Unlike traditional pigs, Ice Pigs use a slush ice mixture to clean and remove deposits without causing damage to the pipeline.

Key Characteristics of Ice Pigging

  • Non-abrasive cleaning: Ice Pigging is non-abrasive, making it ideal for delicate pipelines and those transporting sensitive materials.
  • Minimised waste generation: The ice slush used in this technique melts during the process, leaving behind minimal waste and reducing environmental impact. There is very low risk - at the very worst the ice melts!
  • Versatility: Ice Pigging is can be used in various pipework, including metal, plastic and composite, making it a versatile solution for diverse industry needs.

Benefits of Ice Pigging

  1. Efficient deposit removal: Ice Pigging efficiently removes stubborn deposits, ensuring pipelines operate at maximum capacity and efficiency.
  2. Reduced downtime: The non-destructive nature of Ice Pigging minimises the need for extensive downtime, contributing to increased operational efficiency.
  3. Cost-effective maintenance: The reduced environmental impact and minimal waste generation make Ice Pigging a cost-effective and environmentally friendly maintenance option.
