Curran - Exchanger Tube Cleaning
Curran tube ID dry grit blast cleaning method has elevated expectations of tube cleanliness for Non-Destructive Evaluation (NDE). Never again compromise PEI data with poor inspections as a result of “dirty tubes.” Using high velocity, high pressure air, Curran is expert at scouring tenacious scale and deposits from tube substrate and pits. Curran tube ID cleaning has facilitated high integrity NDE data acquisition of air coolers, SRU exchangers, and surface condensers. Curran crews are expert at performing work in-situ, during turnarounds and equipment maintenance outages, providing vacuum containment to eliminate nuisance dust, and capture all waste debris.
- Refinery air coolers, hydrocarbon condensing units
- Surface condensers, cooling water exchangers
- SRU – Claus boilers, WHBs, tail gas units, condensers
- Furnace tubes, tubular reactors
- All metallurgy, and U tube type
- Cleaner tubes allow a greater probe fill factor and more accuracy in sizing small defects
- Reduced “background noise” and faster data acquisition and analysis time
- In-situ scope execution, containment of dry waste and airborne debris
- Minimize impacts to other planned work in vicinity of Curran cleaning
Cleaning the ID of air cooler tubes for inspection using Curran cleaning method overcomes the issues associated with hydro blasting. Curran crews can execute work on existing catwalks, use vacuum tight containment, and bridge headers using proprietary tube-end to tube-end pitch and catch system. Curran cleaning of air coolers has become a best practice at many refineries across the globe.
At many refineries Curran provides “operational cleaning” of tube IDs too, returning heat transfer duty by effectively cleaning scale from tubes not captured in the NDE scope of work. Contact Curran to discuss your tube NDE and maintenance cleaning strategy.
Refinery clients and NDE inspection companies around the world have found Curran cleaning as a “best practice” for tube surface prep:
