Curran’s advanced dry grit blasting technology uses patented high-velocity nozzles to remove tenacious scale, fouling, and deposits from heat exchanger tube IDs. Our turbulent, high-pressure air delivery system provides 2X standard velocity for complete surface preparation, achieving NACE 1 white metal cleanliness without water introduction. This process enables superior NDE data acquisition for IRIS, RFT, and ECT inspection methods while extending equipment reliability.
Traditional hydro blasting and mechanical cleaning methods fail to achieve inspection-ready tube surfaces. Repeated cleaning cycles create project delays and compromise NDE data quality.
High-pressure water inadequate
Curran’s patented dry grit blasting delivers first-time cleanliness with predictable cleaning schedules and superior surface preparation.
Required cleaning cycles
Our advanced grit blasting technology removes fouling and scale to restore heat transfer efficiency while preparing tubes for accurate inspection. This process reduces maintenance costs, extends equipment life, and enhances system reliability through superior surface preparation.
Complete scale removal enables accurate defect detection with greater fill factor and reduced background noise for faster data acquisition.
Established per-tube cleaning times eliminate rework cycles and provide reliable turnaround planning with consistent results.
Dry abrasive process prevents moisture-related corrosion while eliminating drying time before inspection procedures.
Thorough cleaning reduces corrosion potential and maintains tube integrity for continued reliable operation.
Fouling removal restores thermal performance, reducing energy consumption and enhancing system performance.
First-time cleaning quality minimizes repeated procedures and associated downtime expenses.
