Fouled boiler tubes can cripple plant efficiency and rack up costly maintenance bills — but Curran International has perfected a proven solution.
The Costly Impact of Fouled Boiler Tubes
Boiler tube fouling is a common headache for plant maintenance teams. Without a reliable cleaning procedure, tubes quickly accumulate hard deposits and scales, causing:
- Reduced heat transfer efficiency
- Increased fuel consumption and energy costs
- Accelerated under-deposit corrosion
- Frequent shutdowns and expensive maintenance
Many plants struggle with repetitive cleaning cycles that revisit the same tubes every few days — an inefficient and costly approach.
Why Curran’s Dry Grit Blasting is the Superior Tube Cleaning Method
With over 30 years of experience, Curran International has refined dry abrasive grit blasting to deliver predictable, thorough, and damage-free tube cleaning. Unlike water blasting, dry grit:
- Does not react with sulfur deposits that can form sulfuric acid and damage tubes
- Works safely around existing refractory linings
- Effectively removes thick, rock-hard scale and bulk deposits in as little as 30 seconds per tube
- Scours tube interiors at high velocity, cleaning even pits and crevices deep down the tube
This results in tubes cleaned to NDE (Near Dry Exhaust) standards, enabling more accurate inspection and better maintenance planning.
Innovative Anti-Fouling Coatings: Curramix for Long-Term Efficiency
After cleaning, Curran offers Curramix, an advanced thin film (less than 50 microns) anti-fouling coating designed for many non-aqueous services. Curramix:
- Cures at ambient temperatures
- Withstands temperatures up to 2000°F
- Maintains heat transfer efficiency due to its ultra-thin profile
- Significantly reduces deposit buildup and fouling
- Mitigates under-deposit corrosion to extend tube life
Ideal for application on new units or cleaned tubes during planned turnarounds, Curramix helps maintain peak heat exchanger performance between maintenance cycles.
