  • Composite repair of oil pipe in the Middle East

Composite Repairs

Composite repairs enable reinstatement of the structural integrity of steel and other structures.  Total Solutions provides composite repairs and comes with Lloyds register type approval for application on all manner of structures.  The system we utilise consists of:

  1. Fibres: Glass or Carbon (various woven cloth architectures)
  2. Resin (matrix): Epoxy (with various hardeners)
  3. Primer: Adhesion promoting layer (silane based)
  4. Installation: Hand applied, wet lay-up system, i.e. the resin is worked into the fibre reinforcement on site then directly applied over the defected area

The composite repair system can be used in the following areas:

  • Pipelines
  • Caissons and risers
  • Tanks
  • Roofs
  • Beams
  • Struts
  • Vessels
  • Internal defects
  • External defects
  • Through wall defects
  • Cracks (under certain conditions)

The composite repair system has also been validated for the following substrates:

  • Carbon Steel
  • Duplex / Super Duplex
  • Cast iron
  • 6 Moly
  • 304 / 316L Stainless Steel
  • Cunifer
  • Titanium
  • GRP
  • Concrete

The advantages of using composite repairs over structural replacement include:

  • No hot work are undertaken
  • The system can be applied on a live plant
  • The technology is corrosion resistant
  • Minimal facilities are required
  • Can repair most defect types and service conditions
  • Provides significant cost savings
