About Us

Our company

Cokebusters is an international company specialising in the mechanical decoking and in-line inspection of process piping within fired heaters, HRSG/OTSG boilers, transfer lines and pipelines from a 2½” – 12″ internal diameter. From our two headquarters in the United Kingdom and the United States, we are able to consistently deliver high quality services to the oil and petrochemical industries worldwide.


Our industry leading scraper pigs have been developed to be tough enough to effectively remove fouling but also retain a degree of flexibility to avoid damage to tube walls, navigate plug headers and other restrictions.

Our Merlin in-line inspection tool or “Smartpig” was developed to overcome difficulties with inspecting certain furnace types.

Thanks to its narrow passageway capability, it can be used to inspect furnaces with plug headers featuring a central crossover passage with a 3″ diameter, as well as 3″ schedule 160 tubes with an internal diameter of 2.5″ (63.5mm).


In addition to our scraper and inspection pigs, our bespoke double pumping units are developed and manufactured at our Technology Centre in the UK and our Houston facility in the US.  Our highly-skilled welders and fitters work alongside the experienced site operators to ensure that each unit is manufactured to exacting standards.

Our story

Back in 1993, the founding members of the Cokebusters team worked on the first mechanical decoke in Europe.  Keen to find a way to prove the process worked, they began research and development of a new “Smartpig” in the late 1990s and the first patent application was made in May 2000.

Having already accrued over a decade of experience in the field, Chairman John Phipps MBE incorporated Cokebusters Ltd. in April 2005 bringing “pigging” and tube inspection together under one roof.  The company has been going from strength to strength ever since and is still the only option for clients seeking this combined service.  Our team of engineers and operators continuing to develop innovative solutions which enable us to best serve our clients around the world.

“We are getting better all the time. We’ll continue using our experience and revenue to invest in research and development as we help make the energy industry cleaner and more efficient, develop export performance and create good quality employment opportunities.”
