| 20100000621 | Method for repairing flexible tube - Around a damaged area of a jacket of a flexible tube, a top coat layer whose adhesion to a polymer layer is weak is peeled off with an adhesive tape. The damaged area and its immediate surrounding area are sanded, and then wiped with ethanol for cleaning. A main agent and a hardening agent are heated and defoamed while being mixed to prepare a repair material. The repair material is applied to the damaged area and the immediate surrounding area. A heat shrink tube is opened along slits in an end portion and covers the flexible tube. The heat shrink tube is shrunk with hot air, pressing the repair material and making it flush with a surface of the jacket. The flexible tube is heated with an electric hot plate to harden the repair material. Thereafter, the heat shrink tube is peeled off from the flexible tube. | 01-07-2010 |
| 20100012215 | Composite Load Transferring Technique - A method for repairing and reinforcing a pipeline includes covering a defect in a pipeline section with a composite wrap, isolating the wrap from the ambient environment, and applying a compressive force on the wrap so that the pressure on the wrap is substantially equal to the pipeline pressure. Isolating the wrap involves the use of a housing having a cavity that substantially conforms to the shape of the wrapped section. The cavity may contain a pressurized gas or liquid. Because the pressure acting on the surface of the wrap is at least substantially equal to the pressure of the pipeline section, the wrap cures as if the pipeline is at zero pressure. Once the wrap has effectively cured, the compressive force may be relieved and the housing removed. The composite is now under load and is immediately sharing load with the pipeline. | 01-21-2010 |
