We provide comprehensive pipeline inspection services for hydraulic pipelines as a key step in precommissioning, installation, or replacement projects, ensuring systems meet safety, reliability, and operational standards before startup.
Pipeline Inspection in Precommissioning & Installation
Purpose & Importance
Pipeline inspection serves to:
- Validate construction quality and pipeline integrity
- Detect and address leaks, deformation, or internal damage
- Certify compliance with engineering and safety regulations before operational handover
Inspection Tasks & Stages
- Visual and External Inspection
- Assess welds, supports, and external surfaces for defects, damage, or corrosion during and after installation.
- Internal Geometry & Cleaning
- Pigging: Mechanical pipeline cleaning using pigs (specialized devices) that scour internal surfaces and remove construction debris, scale, and contaminants. This is essential for accurate testing and long-term reliability.
- Caliper Pigging: Specialty pigs equipped with sensors measure internal diameter, detect obstructions or bends, and record the pipeline’s internal geometry for compliance with design specifications.
- Pipeline Integrity Testing
- Hydrostatic Testing: Filling the pipeline with water and pressurizing above its design limits to verify strength and leak-tightness at all joints, welds, and connections. Any pressure loss indicates a potential leak or fault.
- Leak Detection: Methods include acoustic emission testing (listening for fluid escape), tracer gas testing (detecting micro-leaks), and pressure decay monitoring.
- Drying & Preservation
- After hydrotesting, the pipeline is dried using compressed air, nitrogen purging, or desiccant drying equipment to prevent internal corrosion and contamination, meeting specified dew point standards.
- Documentation & Certification
- All inspection and test data are recorded, and certified reports are issued to validate pipeline readiness for commissioning.
Inspection for Replacements & Upgrades
When replacing old pipelines:
- The same standards for cleaning, gauging, hydrotesting, and leak detection apply as for new installations, often with added emphasis on detecting legacy corrosion or defects in transition areas.
