When chemical cleaning reaches its limits, high-pressure automated hydroblasting restores your heat exchangers, piping, and tanks — faster, safer, and without confined space entry.
With automation, our highly trained operators and technicians can run several high-pressure water pumps and hydroblasting hoses simultaneously, from a safe distance. It's different from autonomous cleaning, which involves robots (and which is also a service we offer). With automated hydroblasting, our technicians are making cleaning decisions and performing the cleaning using highly specialized equipment. The result is that your equipment is optimized for heat exchange and pressure, and downtime is kept to a minimum.
Scale buildup, hydrocarbon fouling, and debris accumulation inside your heat exchangers and piping doesn't just reduce efficiency — it accelerates wear and can force an unplanned shutdown at the worst possible time.
When injection treatment and chemical cleaning can't restore your assets, hydroblasting is often the last option before a costly replacement. Sierra mobilizes quickly and gets your equipment back online.
Hydroblasting isn't always the first solution — but when these situations arise, it's typically the fastest and most effective path back to normal operations.
Sierra's automated hydroblasting equipment is a step beyond traditional hand lancing — here's how it changes the job.
Sierra tailors the approach to your specific equipment and fouling challenge. All services are available as part of a custom cleaning plan.
The StoneAge AutoBox ABX-2L eliminates hand lancing — one operator runs two lances simultaneously, forward and back, with engineering controls that make the process hands-free and far more consistent. Also available in hand-lancing configuration for interference issues and smaller exchangers.
Clears pipes fouled with hydrocarbons, scale, or unknown sources. Pipe diameter is not a limitation — Sierra handles 1/2-inch to 40-inch pipe using two specialized tools: the BJV slow-rotating 2D tool on a tracked centralizer, and the 2-inch Badger high-speed swivel for U-tubes and long-radius elbows.
Two different shotgun heads allow surface-level and tube-bundle-depth cleaning. The rotating two-head tip removes seating surface scale and fouling effectively. All shotgunners are protected by a 40,000 PSI shroud and TurtleSkin PPE — engineered for safety at extreme pressures.
Sierra's 3D-head tank cleaner eliminates the need to enter the tank or vessel entirely — no Permit-Required Confined Space Entry, no standby rescue services required. High-volume, high-pressure jet streams reach all interior surfaces. Unique advantage: H₂S and explosive gas chemical inhibitors can be added to the cleaning process.
Sierra offers all three methods and will recommend the right approach for your equipment and fouling situation.
| Criteria | Manual Hand Lancing | Automated Hydroblasting ★ Recommended |
|---|---|---|
| Operator position | ✗ Near or inside vessel | ✓ Safe standoff distance |
| Simultaneous lanes | ✗ One lane at a time | ✓ Multiple simultaneous |
| Pressure consistency | ✗ Inconsistent — fatigue dependent | ✓ Consistent pressure & angle |
| Operator fatigue/risk | ✗ Higher fatigue = higher risk | ✓ Less exposure & fatigue |
| Complex fouling flexibility | ✓ Good for small areas | ✓ Ideal for large exchangers & tanks |
| Best use case | Small, hard-to-reach areas | Large exchangers, tanks, piping systems |
"Our exchanger was completely clogged with mol sieve dust and heavy hydrocarbons. Replacing it meant 7 months of lead time and $500,000 in parts — plus over $4 million in lost revenue from the shutdown. Sierra had it cleaned and returned to us in 12 hours."
Sierra's hydroblasting team will evaluate your equipment, fouling type, and site conditions to recommend the best combination of methods. We'll discuss all options with you to maximize safety, speed, value, and cleaning effectiveness.
