Before any cleaning activity begins, our team conducts a detailed site survey to understand:

• Equipment type & metallurgy
• Severity of fouling
• Operating conditions & history
• System design, accessibility
• Safety hazards & confined space

This helps us formulate a precise and tailored cleaning strategy.

Based on survey findings, our experts select the most suitable:

• Cleaning chemicals (acidic, alkaline, neutral, solvents, foams, inhibitors)
• Corrosion inhibitors / surfactants
• Passivation agents
• Neutralizing chemicals
• Wastewater treatment chemicals

Each selection is based on equipment metallurgy, contaminant type, safety considerations, and environmental norms.

A detailed Method Statement is prepared for client approval, covering:

• Complete cleaning sequence
• Flow diagrams & circulation
• Chemical concentrations & temperature settings
• Wastewater handling methodology
• Manpower deployment & equipment list

This ensures transparency and alignment with client expectations before execution.

VESPL strictly follows “Zero Harm” principles during all projects. Safety preparation includes:

• HIRA / Risk assessment
• Tool Box Talks (TBT) before each shift
• PPE enforcement
• Isolation / LOTO procedures
• Provision of emergency equipment & rescue readiness
• Continuous supervision by certified Safety Officers

Safety is monitored throughout the entire job.

Depending on the equipment and objectives, we execute cleaning through:

• Chemical circulation
• Online cleaning
• Immersion pickling / passivation
• Hydro-jetting
• Foam cleaning
• High-flow oil flushing
• Descaling & decontamination

Adjustments are made scientifically to ensure optimum results.

All generated effluent undergoes safe treatment:

• pH correction
• Sludge settlement & filtration
• Neutralization
• Filtration and safe transfer
• Disposal as per Pollution Control Board norms

We ensure strict environmental compliance and minimal impact on the client's facility.

Once cleaning is complete, we carry out:

• Visual / Boroscope inspection
• Boroscope inspection (if required)
• Flow tests & efficiency checks
• Cooling efficiency checks
• Tube/tank surface verification
• Corrosion and passivity checks

Client representatives are involved at every stage to confirm results.

A detailed Post-Cleaning Report is prepared, including:

• Work summary
• Chemicals used and consumption
• Technical parameters & methodology
• Pre-cleaning & post-cleaning observations
• Safety compliance details
• Effluent treatment summary
• Photographs (before & after)
• Recommendations for future maintenance

This report becomes part of the client’s official maintenance records.
