Coatings - Internal Tube Cleaning

  • Park Derochie has been successfully abrasively cleaning the vertical reactor tubes at Dow Chemical for over 15 years.
  • In 2006, Esso approached Park Derochie to abrasively clean the horizontal tubes inside three sulfur condensers. Upon completion, Park Derochie was informed that in 30+ years of utilizing different contractors, PD had completed the sulfur condensers in record time with a state of cleanliness that no other contractor had previously been able to achieve.
  • Since then Park Derochie has also performed "Abrasive Internal Drill Blast &Tube Cleaning" for Shell Canada and Semcams inside their large gas facilities.


Park Derochie has developed a Push/Pull method to abrasively blast clean the inside of various sizes of tubes.

This method employs the use of a conventional abrasive blasting unit installed on one end of the exchanger and a VecLoader vacuum installed at the other to achieve the push / pull.

This allows Park Derochie to abrasively clean an exchanger while other contractors are in the immediate area without causing any health or safety concerns.
