We understand that Ice Pigging may be a new technique for many of our customers. We therefore work with you throughout the process, explaining how it works, where it can be applied and the potential benefits to your operation.
Our aim is simple: to provide an effective, practical cleaning solution that saves time, reduces resource use and improves process performance.
Why Choose Ice Pigging?
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 can be used in various pipework, including metal, plastic and composite. Ice can negotiate topologies that traditional pigs can’t, such as valves, pumps and changes in diameter, making it a versatile solution for diverse industry needs.
Benefits of Ice Pigging
- Efficient deposit removal: Ice Pigging efficiently removes stubborn deposits, ensuring pipelines operate at maximum capacity and efficiency.
- Cost-effective maintenance: The reduced environmental impact and minimal waste generation make Ice Pigging a cost-effective and environmentally friendly maintenance option.
- Reduced downtime: The non-destructive nature of Ice Pigging minimises the need for extensive downtime, contributing to increased operational efficiency.
- Low risk: Ice Pigging is lower risk than traditional pigging - traditional pigs can get stuck or even break apart in the line whereas ice will just melt!
What Is The Process?
It all starts with a chat.
We want to know what your challenges are so that we can give you the right solution. From here we can then build you a bespoke plan of action.
Ice Pigging utilises the special properties of an ice slurry mixture, manufactured by Nivalis designed and built machinery. The ice that is produced has an additive to maintain the freezing point below zero (usually around -5 degrees Celsius). There are different options when it comes to this additive which we will discuss with you to ensure the right type is used for your system.
We will also need to talk through the system's pipe layout with you to ensure we calculate the volumes of ice required for your system.
There are also several different ways in which we can deliver the ice slurry to your system - we will talk through all the options with you working to overcome any logistical issues where possible.
Once the plan is in place, Nivalis can:
- Deliver ice production and delivery equipment to site for the duration of work.
- Work with the customer and other contractors on any enabling works.
- Supply ice delivery and waste removal hoses, along with interface adapters as required.
- Work with the customer on pre and post condition assessments as part of cleaning validation.
- Carry out pre Ice Pigging flow and integrity testing.
- Run Ice Pigging production and delivery operations.
- Work with the customer and contractors to carry out post Ice Pigging flushing and system reinstatement.
- Produce detailed post operation technical analysis and reporting.
