Field-Proven Case Studies
Real-world applications in critical oil and gas infrastructure
Corrosion Repair on 16" Crude Oil Export Line
External corrosion under damaged coating resulted in 40% wall loss over 200mm length. Platform couldn't shut down for hot work. Composite bandage restored structural integrity within 8 hours with zero production interruption.
Emergency Leak Repair on Natural Gas Pipeline
Pinhole leak from external corrosion detected during patrol inspection. Composite repair executed on live pressurized gas line in remote location with 2-person crew. Line remained in service throughout repair process.
High-Temperature Crude Transfer Line Reinforcement
Ultrasonic inspection revealed 35% wall thinning at support saddle location due to flow-accelerated corrosion. High-temperature composite system applied during unit turnaround, eliminating need for spool replacement.
Installation Process Overview
Streamlined application procedure for field technicians
Surface Preparation
Abrasive blast or wire brush to SSPC-SP3/NACE No. 3 standard. Remove all loose scale, rust, and contaminants.
Primer Application
Apply epoxy primer to ensure adhesion. Fill any pits or surface irregularities with putty.
Bandage Wrapping
Activate bandage and wrap circumferentially with 50% overlap. Apply calculated number of layers per design.
Curing & Inspection
Allow 24-hour ambient cure. Perform visual inspection and document repair per QC procedures.
Engineering Design Requirement
All repairs must be designed by qualified engineer per ASME PCC-2 Article 4.1 requirements. Design calculations should consider pipe diameter, wall thickness, defect dimensions, operating pressure, and temperature. Contact our engineering team for design assistance.
