A pressure test device and a pressure test method for a long-distance pipeline

Abstract

The present invention relates to a pressure test device for long-distance pipelines, which includes a water filling unit and a booster unit respectively installed on the first base and the second base; The pipeline includes multiple conveying pipe sections, and valves are installed at the joints between multiple conveying pipe sections; the pressure test method is as follows: use the water filling unit to fill the first conveying pipe section with water, and after the water filling is completed, use the booster unit to fill it with water. Pressurize, and at the same time, the water filling unit fills other conveying pipe sections with water. The pressurizing unit and the flushing unit are used at the same time until the last conveying pipe section. Supercharging; the water filling unit and the supercharging unit are respectively arranged on two bases, which are separately skidded, and the water outlet pipe sections of the water filling unit and the supercharging unit both contain hoses, which are more convenient to move, and can make the water filling unit and the booster unit The pressure unit fills and pressurizes different conveying pipe sections at the same time, which saves time and improves the efficiency of pressure testing.

Description

technical field [0001] The invention relates to a pipeline pressure testing device and a pressure testing method, in particular to a pressure testing device and a pressure testing method for a long-distance pipeline. Background technique [0002] Compared with conventional pipelines and equipment pressure testing, the pressure test link of long-distance pipeline construction has an important feature, that is, the pipeline is long and the pipe diameter is large. This makes pressure testing an important part of long-distance pipeline construction and one of the important links that affect the construction period. The existing pressure test devices are mostly aimed at the equipment and pipelines in the device. The pressure test devices manufactured according to the process plan of the existing pressure test devices are used in the long-distance pipeline pressure test process, which has long water injection, slow pressure rise, and process settings It is not suitable for the pr...
