Cokebusters’ mechanical pigs are purpose-designed tools developed specifically for the controlled mechanical decoking of complex process tubing and pipelines.
As a specialist mechanical pig manufacturer and supplier, Cokebusters designs, fabricates and maintains industrial mechanical pigs in-house to patented designs. This approach provides full control over performance, quality and availability, while enabling rapid response to project-specific and asset-specific requirements.
The mechanical pig portfolio includes approximately 50 incremental pig sizes, covering internal diameters from 1” to 12”. Where required, custom mechanical pigs can be manufactured off-spec to suit unique geometries, operating constraints or cleaning objectives.
All mechanical scraper pigs feature a patented construction, including a soft inner core that allows the pigs to navigate tight geometries such as 1D bends and reduced throat box headers commonly found in fired heaters.
In-house design and manufacture enables Cokebusters to maintain full control of its supply chain and to respond quickly to customisation requests. Pig configurations can be adapted to suit the specific decoking task, asset geometry and operational objectives.
Mechanical pigs are engineered to remove fouling gently and progressively, minimising the risk of tube damage while delivering effective, repeatable cleaning performance and predictable behaviour through complex piping systems.
Mechanical pigs are deployed as part of Cokebusters’ mechanical pigging systems using Double Pumping Units, allowing precise control over flow, pressure and pig movement throughout the decoking process.
Where required, residual water can be removed from process pipework following operations. A full passivation procedure for stainless steel tubing can also be provided in accordance with NACE RP0170 requirements.
Alternative pig designs and configurations can be accommodated to suit unique or non-standard applications, ensuring flexibility across a wide range of assets and mechanical pigging solutions.
Each Double Pumping Unit is fitted with Cokebusters’ proprietary InnerVision™ monitoring system.
Cokebusters operates dedicated test loops at its premises, enabling operators to be process-trained and new pig designs, materials or configurations to be evaluated and validated prior to site deployment.
This continuous development and testing capability ensures that mechanical pigs perform predictably and safely when deployed in challenging industrial environments.
