Abstract
The present invention discloses a technique for removing an oil stealing branch pipe on an oil transporting pipeline, which belongs to the online reparation technology of oil transporting pipelines. The technique comprises the steps that the oil stealing branch pipe is detected, fast low-temperature cured resin is prepared, and the fast low-temperature cured resin is injected into the oil stealing branch pipe; the degree of cure is detected, and the oil stealing branch pipe is eliminated. The fast low-temperature cured resin is composed of polyurethane, epoxy resin, phenolic resin, filling materials and auxiliary agents; prepared resin is detected and controlled by a computer measure and control system, the pressure of 1.0 to 1.5MPa is adopted, and the resin is injected into the oil stealing branch pipe by a high-pressure precision measuring injection pump and is solidified at the temperature of 20 to 30 DEG C in 5 to 30 minutes. The technique has the advantages of simple operation process and quick and safe implementation, and is convenient to popularize and apply.
