Texas Tower VCFE Platformer Tube Side Clean in Holland

Tubes Cleaned Ready for IRIS Inspection

Asset integrity is an essential part of running a plant. IRIS Standard cleanliness is historically difficult to achieve using traditional water jetting often requiring multiple passes, thereby extending the duration of a shutdown unnecessarily and often going into critical path.

On such a costly and critical item such as a VCFE / Texas Tower, it was essential for a Netherlands based refinery to achieve IRIS standard cleanliness. Tube Tech was recommended to them as the ideal specialist for this challenge. Tube Tech provided a newly developed “Enhanced IRIS Standard Cleaning System” using a novel Rotaflex process which ensured all tubes were rapidly cleaned to IRIS inspection standard first time, every time.

The Challenge

Deposit characteristics described as unknown.

  • Client reported that 95% of tubes could be fouled, and 5% of tubes blocked.
  • Client advised that a maximum of 5% of tubes could be blocked.
  • Previous water jetting contractors were unable to achieve IRIS.
  • There were severe time constraints as the refinery was in shutdown.


The Solution

Tube Tech’s bespoke Rotaflex Enhanced IRIS Standard Cleaning System which included:

  • Rapid Tube Blockage Location Technology
  • Soft Drill tube Unblocking Process
  • Multiple Tube Descaling Systems
  • High Speed Enhanced Tube Cleanliness to allow both Eddy Current and IRIS Inspection Standard.
