Maximum service pressure is dependent on diameter of pipe, design temperature and thickness of repair applied. The majority of applications will be at up to 100bar (1500psi), but current experience exceeds 200bar (3000psi).

The FurmaCarbon system utilises a range of epoxy resins to address different service temperature requirements. Two fabric styles have been qualified to ensure the full capacity of the high performance fibres can be utilised. One style (Quad) is ideal for medium pressure components and tees, the other (Biax) is ideal for high pressure and larger diameter pipelines including elbows and reducers. An initial layer of fibre glass is applied to control the performance of the bond and ensure full corrosion protection is achieved.

The resin and fibre are combined on site meaning the system is very versatile in terms of geometries which can be repaired.

Furmanite’s FurmaCarbon is the high performance option for repair and strengthening of pipes even where damage has gone through-wall.

The ultimate strength and stiffness provided by the carbon fibre reinforcement enable applications at pressures ranging from 10 bar (15psi) to over 200bar (3000psi). Repairs can be applied to flat surfaces, tank walls, tank floors as well as pipes, tees, reducers, elbows and other components. The system can carry internal pressure and vacuum loads as well as axial loads, bending moments and shear loads.

FurmaCarbon combines the high performance of carbon fibre reinforcement with the high bond strength and chemical resistance of epoxy resins to produce a system that can be used for the repair of pipes, even when damage has gone throughwall. Supplied in accordance with the requirements of ISO TS 24817 and ASME PCC-2 Article 4.1, each repair is designed to ensure confidence can be placed in the performance of the system. In addition to the testing specified by these guidance notes, the repair system has been tested to prove long term suitability for pipeline repair (including extensive pressure cycling) and the repair of dents. The competence of installers is demonstrated through an externally-approved training course and tracking of experience of each technician.

The combination of hole size that can be sealed with the temperature and pressure of service is assessed in accordance with these guidance documents based on the wide range of validation testing completed. Ideal for local repairs, renovation of entire lines or even corrosion protection, FurmaCarbon provides a cost-effective integrity management solution for demanding applications.
