Heavy plant surface preparation and chemical line flushing.
Heavy plant surface preparation and chemical line flushing.
Manufacturing & Heavy Industrial Facilities
Heavy plant surface preparation, chemical transfer line flushing, and foundry scale abatement.
Manufacturing complexes, automotive assembly plants, and heavy fabrication mills endure relentless carbon fouling, chemical scale, and resin buildup across critical heat exchangers, storage tanks, and structural foundations.
Chow Marine provides engineered decontamination packages designed to restore plant components down to white metal specifications without causing abrasive media contamination to precision machinery. Utilizing water-only ultra-high pressure hydro-blasting at pressures up to 40,000 PSI, our mobile systems eliminate hardened resins, chemical scale, polymer deposits, and metallurgical slag without damaging the substrate steel.
Our teams operate specialized positive-pressure air apparatus and continuous 4-gas atmospheric monitors to safely perform work in permit-required confined spaces, reactor vessels, dip tanks, and chemical line headers. All wastewater and dislodged solids are routed directly into high-volume closed-loop vacuum recovery units rated at 3,500 CFM, preventing hazardous runoff and ensuring total regulatory compliance with provincial and federal environmental mandates.
By replacing traditional sandblasting with zero-spark hydro-demolition, Chow Marine enables manufacturing plants to conduct critical maintenance during planned turnaround outages while surrounding operations continue without explosion hazard or airborne particulate risks.
Atmospheric & Substrate Survey
Continuous 4-gas analysis, LEL verification, ultrasonic wall thickness gauging, and hazardous waste profile logging before any technician entry.
Containment & Vacuum Isolation
Installation of chemical-resistant berms, splash curtains, and high-vacuum recovery hoses to ensure 100% effluent capture.
40,000 PSI Hydro-Jetting
Deployment of automated rotary lances and magnetic crawlers to strip polymerized chemical cakes and mill scale down to bare steel.
Inspection & Return-to-Service
SSPC-SP 12 / NACE No. 5 surface cleanliness verification, certified waste manifests, and formal release for immediate plant recommissioning.

How does UHP water jetting protect precision manufacturing machinery?
add
How does UHP water jetting protect precision manufacturing machinery?
Unlike sandblasting or abrasive grit, ultra-high pressure water jetting leaves no abrasive particles behind that could enter bearing assemblies, gearboxes, or hydraulic systems. The pure water jet removes coatings and scale while leaving parent metal completely intact.

What permits and certifications do your industrial crews carry?
add
What permits and certifications do your industrial crews carry?
All Chow Marine technicians are certified in Confined Space Entry & Rescue, Working at Heights, Hazardous Material Handling (WHMIS), and operate under strict ISO 9001 quality management procedures.
03
Can cleaning be performed while adjacent production lines remain operational?
add
Can cleaning be performed while adjacent production lines remain operational?
Yes. Our specialized negative-pressure containment enclosures and zero-spark equipment allow us to isolate the work zone completely, preventing water mist or chemical odors from affecting surrounding production cells.
