When to Use Composite Repair

Composite wraps provide a permanent or temporary reinforcement for pipelines without requiring a shutdown. It is the most efficient alternative to welded sleeves or full cut-outs.

  • Cannot take line out of service
  • High-consequence areas
  • Complex geometries (tees, elbows)
  • Space-constrained environments

Defects We Address

External Corrosion

Restoring hoop strength lost to wall thinning.

Mechanical Damage

Gouges, scratches, and arc burns.

Dents

Restraining cyclic fatigue in dented pipe segments.

Proprietary System

The RRL Rapid Repair System

Raphoon uses the RRL repair exclusively for external corrosion repairs. The RRL wrap uses a filler material that cures instantly, which allows for rapid application and backfill in just a few hours — significantly less open-hole time than conventional composite systems.

What It Is

Cold Spray Metal Filler

The key difference of the RRL repair is the Cold Sprayed metal deposition that makes up the filler material. Cold Spray metal has better bond strength, compressive strength, and tensile strength than any other filler material used in the pipeline repair market.

Why this mattersConventional repair filler materials (epoxy grout, urethane) are limited in their mechanical properties. Cold Spray metal behaves more like the steel it is replacing, which means the repair does not create a soft spot in the system.
ILI Compatibility

Visible to ILI Tools

The RRL repair ensures you will not accidentally dig up a previously repaired anomaly. After repair, the defect no longer shows up on future ILI scans — instead, it appears as a thicker wall section that can be verified against records. Detectable by UT, MFL, and other ILI methods.

Why this mattersMany composite repair materials are invisible to ILI. A pipeline operator cannot manage what they cannot detect. The RRL's ILI visibility means repairs remain in your records and your integrity management program, not just in the contractor's notes.
Aerospace Origin

Patented Application Process

The RRL system uses aerospace industry technology adapted for pipeline field conditions. The filler material's chemistry closely matches the carbon steel used in pipeline construction. The patented process enables repair, cure, and backfill in hours, not days.

Why this mattersAn open excavation is an operational liability. The ability to complete a repair in the same day the anomaly is exposed reduces downtime, safety exposure, and regulatory scrutiny.

Engineering Standards

Our evaluation and consulting approach strictly follows ASME PCC-2 Article 4.1 and ISO 24817. We verify that the composite system's math works for your specific SMYS, operating pressure, and defect depth.

A composite repair is only as good as its surface preparation and mathematical validation. We ensure both are flawless.

Standards & Technical References

The governing documents behind composite repair sizing and qualification. Linked here for engineers who need to trace the methodology.

ASME PCC-2 — Repair of Pressure Equipment and Piping

The American standard governing the design, engineering, and installation of composite repairs on pipelines. Article 4.1 specifically addresses fiber-reinforced composite repair systems for non-leaking defects.

Why this mattersASME PCC-2 is the basis for the layer count and repair length calculations in our free composite repair calculator. If your operator requires PCC-2 compliance, the math behind the system is fully traceable through this standard.
ASME PCC-2 Standard

ISO 24817 — Composite Repairs for Pipework

The international standard for composite repair design, qualification, and installation for pipelines and pipework. Widely used outside North America and increasingly required by international operators.

Why this mattersISO 24817 and ASME PCC-2 use a compatible strain-based methodology. Our calculator follows the ISO 24817 approach for temperature-adjusted repair sizing. If your project spec references ISO 24817, the methodology is the same.
