Composite Repair Systems
Non-metallic, high-strength repair for pipelines and structures — no welding, no shutdown, suitable for live systems, and engineered to recognised international standards.
Structural Reinforcement Without Hot Work or Shutdown
JST Group delivers composite repair systems for pipelines and structures requiring structural reinforcement without hot work or shutdowns. Composite repairs offer a lightweight, high-strength solution for corrosion damage, mechanical defects, and wall-thickness loss.
Applied cold to the external surface of the asset, composite systems restore pressure capacity and structural integrity to operating pipelines and structures — engineered and documented to ISO 24817 and ASME PCC-2 standards.
Why Composite Repair?
A proven alternative to welded repairs and pipeline replacement — faster, safer, and applicable to live and pressurised systems.
No Welding or Hot Work
Cold-applied composite systems eliminate the need for welding, grinding, or hot work — safe for live and hazardous-area assets.
High Strength-to-Weight Ratio
Fibre-reinforced composite systems deliver structural performance comparable to steel at a fraction of the weight.
Rapid Installation
Systems are typically installed within hours — reducing downtime and production loss compared to conventional repair methods.
Suitable for Live Systems
Composite repairs can be applied to pressurised and operating pipelines and structures without shutdown or isolation.
Where Composite Repair Systems Are Used
Pipelines with Corrosion Damage
External corrosion, pitting, and wall-thickness loss on buried, aboveground, and subsea pipelines.
Pressure Pipes & Fittings
Reinforcement of corroded, dented, or mechanically damaged pressure piping and fittings.
Structural Steel Reinforcement
Strengthening of corroded or mechanically damaged structural steelwork without welding or replacement.
Offshore & Subsea Structures
Riser repairs, jacket members, and subsea pipeline sections requiring structural reinforcement.
Industrial Plant Piping
Process piping, headers, and manifolds in operating refineries, chemical plants, and production facilities.
Emergency Repair
Rapid-deployment composite repair for emergency situations requiring an immediate, temporary or permanent solution.
How We Deliver It
From engineering assessment through to quality-controlled application — a fully managed composite repair service.
Engineering Assessment
Defect characterisation, fitness-for-service evaluation, and determination of repair design parameters including pressure rating and required reinforcement thickness.
Repair Design
Engineering calculation and repair system selection in accordance with recognised standards (ISO 24817, ASME PCC-2) — documented and client-approved.
Surface Preparation
Substrate cleaning and preparation to the required standard, including rust removal, degreasing, and profile preparation for composite bonding.
Application & Quality
Composite system application by trained technicians, with documentation of laminate thickness, cure monitoring, and post-installation inspection.
