Discussion about Application of Composite Repair Technique in Pipeline Engineering
Fiber composite repair reinforced steel pipeline structure is new technology developed in the nineties of the twentieth century, the technology is highly regarded in the world, has already become a development trend of repair reinforced steel pipeline structure. This paper reviews the problem existing, such as interfacial debonding, layered, empty drum, blank holder and no or incomplete sealing in the repair and reinforcement technique of composite during engineering application. The corresponding formation reason is primarily analyzed according to the construction experience. On the basis, it is pointed out that it is very necessary to establish the check and evaluating indicator system of the field construction acceptance process and field application effect of the fiber composite used in repairing and reinforcing the pipeline, which of the aim is to improve the repair and reinforcement quality and to obtain a full and clear understanding about the repair status and effect of the repair points in the repaired service pipeline.
