Abstract
In view of the defects of the high cost and long duration of plugging operation on the pipe orifice, a fast plugging device with o-ring for long-distance pipeline is developed. The structure and its plugging principle of the fast plugging device are introduced; a test is performed by using a plug-ging device with diameter of 1016 mm. The result indicates that when pressure is less than 0.023 MPa inside pipeline, sealing performance is good inside the pipeline. When the external pressure is less than 0.23 MPa, the welding blind plate pipe section is well maintained; it can meet the re-quirements of temporary plugging pipe in the long-distance pipeline construction.
