A hydraulic adapter for installing connecting flanges of an oil pipe comprises a first centralizer, a second centralizer, and a hydraulic cylinder. Tapered cylinders are disposed on the first centralizer. A first flange centralizing protrusion is disposed on the first centralizer. A hydraulic cylinder installation hole is disposed on the first centralizer between two of the tapered cylinders. Tapered protrusions are disposed on the second centralizer and fit with the tapered cylinders disposed on the first centralizer. An adjustment hole is disposed on the second centralizer. A second flange centralizing protrusion is disposed on the second centralizer. A base of the hydraulic cylinder is disposed on an outer side of the first centralizer, and a hydraulic arm of the hydraulic cylinder perforates through the hydraulic cylinder installation hole and the adjustment hole. An extrusion block is disposed at an end of the hydraulic arm.
