● Service Overview
What Is Composite Wrap Repair?
Composite wrap repair is an engineered, non-intrusive method of restoring structural integrity to degraded, corroded, or damaged pipelines and pressure vessels. A high-strength fibre-reinforced polymer (FRP) sleeve is applied directly over the damaged zone while the asset remains in full operation — eliminating costly shutdowns and production deferral.
At Niger Delta Engineering Limited, we deploy industry-leading composite systems backed by rigorous engineering analysis, certified by international standards, and executed by our highly trained field teams across onshore and offshore Niger Delta environments.
● How It Works
Our Repair Methodology
A rigorous, standards-based workflow from initial assessment to final acceptance — executed with precision by NDEL's certified technicians.
● Scope of Application
Where We Deploy Composite Wraps
Our composite repair capability spans the full spectrum of upstream, midstream, and downstream infrastructure across the Niger Delta region.
● Technology
Composite Wrap Systems We Deploy
01
Glass Fibre Epoxy (GFE) Wrap
Cost-effective, high-strength solution for moderate pressure and temperature service. Excellent chemical resistance and flexibility for complex geometries.
02
Carbon Fibre Reinforced Polymer (CFRP)
Ultra-high tensile strength system for maximum MAOP restoration and structural reinforcement. Preferred for critical high-pressure gas service and large-diameter pipe.
03
Aramid / Hybrid Composite Systems
Combination fibre architectures tailored for impact resistance, vibration damping, and mixed loading environments.
04
Metallic Composite Sleeves
Steel-reinforced composite sleeve repairs for high-temperature / high-pressure service and axial load transfer applications where polymer-only systems are insufficient.
05
Clock Spring® / Pre-cured Tape Systems
Rapid deployment pre-cured composite bandage systems for emergency live-line repair — full strength achieved within hours of installation.
● Why Composite Repair?
Advantages Over Traditional Methods
- →No hot work — eliminates fire and explosion risk in hazardous areas
- →Live-line repair capability — zero production downtime
- →Lightweight application — no heavy rigging or scaffolding required
- →Corrosion-resistant repair that outlasts parent metal in aggressive environments
- →Proven design life of 20+ years per ISO 24817 qualification testing
- →Significantly lower overall cost versus cut-out-and-replace spool repairs
- →Applicable to complex geometries: bends, tees, flanges, and reducers
- →Fully traceable engineering calculation package for regulatory submission
- →Compatible with cathodic protection and external coating systems

● Client Feedback
What Our Clients Say
"
NDEL's team completed a critical 20-inch crude line repair in a remote swamp location within 72 hours of notification — full engineering pack and pressure test certification included. Exceptional work.
AO
Adebayo Okonkwo
Pipeline Integrity Manager, Major IOC
"
The composite repair held under full operating pressure. The ASME PCC-2 documentation was accepted by our asset integrity team without any queries. Highly professional.
CI
Chidi Ibezim
Senior Integrity Engineer, E&P Operator
"
We had a significant external corrosion defect on a high-pressure gas riser. NDEL's carbon fibre wrap allowed us to maintain full throughput while the long-term spool replacement was planned. Outstanding result.
