Pipe Reinforcement

Pipe Reinforcement

Composite structural rehabilitation (CSR), more commonly referred to as composite pipe repair or pipe reinforcement, is a system which offers pipe rehabilitation, giving structural strength to corrosion damaged pipework.

The system uses a combination of specialised laminating resins, interlayered with glass reinforced polymers (GRP) composite laminates, to refurbish and repair corrosion damaged pipework, at a fraction of the cost and inconvenience of replacement. It can also be used to help repair damaged areas of other industrial equipment and structures, including tanks and vessels, and even concrete.

Used successfully in the oil & gaspower generationwater & waste and other industries for many years, the composite structural rehabilitation system qualifies under BS EN ISO 24817:2017. This incorporates composite repairs for pipework, both metal and glass reinforced plastic (GRP). The standard ensures that pipework, pipelinestanks and vessels repaired using composite systems are qualified, designed, installed and inspected to meet the relevant specified performance requirements.

CSR is an ideal solution for pipe rehabilitation and pipe reinforcement, restoring strength to capital process equipment, where corrosion has reduced the wall thickness or where damage has occurred. By also providing long term corrosion protection, the life span of the treated pipework, or plant, is greatly increased. This provides significant financial savings and reduced materials wastage. The wrapping system also has the major benefit of being a cold repair technique. This negates the need for hot work on-site, requiring no specialist equipment.

The Corroserve CSR system is compliant to ISO24817, with a tensile testing required under the standard being carried out independently at the University of Strathclyde Advanced Materials Research Laboratory. The following video demonstrates the technique of pipe wrapping and reveals just how structurally strong a completed CSR repair is.

Each repair is uniquely designed to meet specific service demands and the design factors considered include size in geometry of the defect, operating temperature and pressure, and remaining wall thickness.
