Built for
Uptime.
Proven in
the Field.
International fast-track commissioning and cleaning specialists. Steam blowing, oil flushing, chemical cleaning, hydro jetting, nitrogen, and mechanical completions — engineered first, deployed with zero deviation, and reported to your team every day.
Seven Service Lines. One Call.
From first flush to final turnover — proprietary equipment, certified crews, and engineered procedures for every phase of startup, maintenance, and shutdown.
Pre-Commissioning & Commissioning
Clean systems, on schedule, before first fire. We engineer the procedure, bring the equipment, and prove the result — so startup happens on the day it was planned.
- QuietBlow™ near-sonic steam blowing with custom silencing and targeting
- Air and nitrogen blowing with LOK's Full Flow Silencer™
- High velocity water flushing of complex piping systems
- Hydrostatic testing integrated into cleaning phases
- Site-specific pre-engineering and CAD procedures
- Standards
- ISA 77.70 / ASME B31.1
- Steam Blows
- Near-sonic velocity
- Testing
- Integrated, not standalone
- Verification
- Post-flush inspection
Oil Flushing
High velocity flushing that reaches cleanliness targets fast — and proves it with real-time particle data, not a guess.
- High velocity lube oil flushing for new builds and in-service systems
- Hot oil flushing to accelerate contaminant removal
- Hydraulic system flushing and oil conditioning
- Real-time filtration with electronic particle counters
- Documented cleanliness sign-off before startup
- Filtration
- 1–30 micron, real time
- Monitoring
- Electronic particle counts
- Acceptance
- ISO cleanliness verified
- Systems
- Lube, hot oil, hydraulic
Chemical Cleaning
End-to-end chemical cleaning under a written, stage-by-stage procedure with hold points — so every step is controlled, contained, and signed off before the next begins.
- Degreasing, descaling, and iron oxide removal
- Passivation to protect cleaned surfaces
- Boilers, exchangers, columns, towers, tanks, and vessels
- Closed-loop circulation and soak procedures
- Segregated waste streams with manifested disposal
- Procedure
- Written, with hold points
- Containment
- Fully enclosed
- Waste
- Segregated & manifested
- Scope
- Startup, TA, or in-service
Hydro Jetting & Milling
Containerized high-pressure units and LOK-engineered rotary nozzles that cut through the hardest deposits — with results in as little as two days.
- Exchanger bundles — tube side and shell side
- Process lines, drains, and sewers
- Tanks, vessels, and towers
- Hydro milling of hardened deposits and scale
- WJTA-certified operators at 20,000 PSI
- Pressure
- 5,000–40,000 PSI
- Power
- 100–400 HP units
- Tooling
- LOK rotary nozzles
- Results
- In as little as 2 days
Nitrogen Services
Inert, dry, and safe — nitrogen work that takes systems in and out of service without delay, from process units to the well site.
- Nitrogen purging and displacement — LEL and oxygen freeing
- Drying and preservation of lines and vessels
- Pneumatic and leak testing
- Nitrogen blowing for debris removal
- Well-site nitrogen support and well remediation
- Purging
- LEL / O₂ verified
- Blowing
- Full Flow Silencer™
- Testing
- Pneumatic & leak
- Deployment
- Plant or well site
Mechanical Completions & Inspection
The paperwork that closes a system out — captured in the field, witnessed on the spot, and handed over clean. No chasing signatures at turnover.
- Hydrostatic test records captured at the test
- Witness joint registers, signed in the field
- Flange management and joint-by-joint tracking
- Borescope inspection to verify internal cleanliness
- System-by-system turnover documentation
- Capture
- Digital, at the joint
- Witness
- Signed on site
- Inspection
- Borescope verified
- Handover
- Turnover-ready packages

Field-Ready.
Engineered First. Proven Last.
Every LOK job runs the same five-step sequence — whether it's a two-day jetting call or a full commissioning scope.
- 1EngineerSite-specific procedures and CAD drawings, with hold points, built before a single hose is laid.
- 2MobilizeCertified crew and LOK equipment on site within 24–48 hours, anywhere in the USA.
- 3ExecuteLOKed-in safety on every task. No step moves forward until the one before it is signed off.
- 4VerifyParticle counts, pressure holds, borescope checks, and witnessed joints — proof, not promises.
- 5ReportDaily site reports in your client portal, and a clean turnover package the day the job closes.
Why LOK
Proprietary equipment. Certified crews. One call. Full scope. Full visibility.
You See the Job
