Embodiment 1

[0024] In order to overcome the problem that the existing pig transceiver device is fixed and not easy to move, and the pig transceiver device has only one branch and cannot switch between the pigging process and the production process, this embodiment provides a method such as figure 1 , figure 2 and image 3 The movable pig sending and receiving skid-mounted device shown includes a skid body 1, a transceiver cylinder body 2, and a plurality of supports 3 supporting the transceiver cylinder body 2 on the skid body 1, and the bottom of the skid body 1 is provided with Bolts 13 fixedly connected to the pre-buried strip foundation 14 in the station, a branch pipeline 4 is connected to one side of the sending and receiving cylinder 2, and the right end of the branch pipeline 4 and the right end of the sending and receiving cylinder 2 are pigged The tee-5 is connected, the left end of the branch pipeline 4 is connected to the left end side wall of the sending and receiving cylin...

Embodiment 2

[0032] On the basis of Example 1, since the stress analysis of the branch pipeline 4 system of the pig transceiver skid is a stress concentration position, the left end of the branch pipeline 4 is horizontally offset by the distance of the support 3 supporting the transceiver cylinder 2 For more than double the diameter of the branch pipeline 4.

[0033] Ball valve two 17 and ball valve three 18 are arranged on the pipelines at both ends of the pigging tee two 7 of the branch pipeline 4, and a ball valve one is arranged between the right end of the sending and receiving cylinder 2 and the pigging tee one 5 16. The sewage discharge pipeline 11 is equipped with a sewage discharge ball valve 19 and a sewage discharge ball valve 2 20, the discharge pipeline 12 is equipped with a discharge ball valve 21, and the sending and receiving cylinder 2 is equipped with a pressure gauge 22. The ball valve controls the opening and closing of the pipeline, which improves the safety of the on-...

Abstract

The invention specifically provides a movable tube cleaner receiving and dispatching skid-mounted device which comprise a skid body, a receiving and dispatching cylinder and a plurality of supports. A bolt fixedly connected with a strip-shaped foundation embedded in a station is arranged at the bottom of the skid body. One side of the receiving and dispatching cylinder is connected with a branch pipeline. The right end of the branch pipeline and the right end of the receiving and dispatching cylinder are connected through a first tube cleaning tee joint. The left end of the branch pipeline and the side wall of the left end of the receiving and dispatching cylinder are connected. The first tube cleaning tee joint is connected with an inlet flange connector. A second tube cleaning tee joint is installed in the middle of the branch pipeline and connected with an outlet flange connector. A sewage discharge outlet of the receiving and dispatching cylinder is connected with a sewage discharge flange connector through a sewage discharge pipeline. An emptying opening of the receiving and dispatching cylinder is connected with an emptying flange connector through an emptying pipeline. The movable tube cleaner receiving and dispatching skid-mounted device is simple and practical, and rapid installation and repeated utilization can be achieved; except for a tube cleaner receiving and dispatching function, the branch pipeline can be used as a conveying pipeline for the long conveying pipeline station for a long time, and the tube cleaning procedure and the production procedure are switched.

Description

technical field [0001] The invention belongs to the technical field of pipe pigging for transporting oil and gas pipelines, and in particular relates to a movable pig sending and receiving skid-mounted device. Background technique [0002] According to the plan of China National Petroleum Corporation, CNPC will increase the investment and construction of oil and gas storage and transportation investment facilities during the "Twelfth Five-Year Plan" period, and the pipeline construction is expected to be about 50,000 kilometers. With the construction of more and more oil and gas pipelines, it is particularly important to ensure that the completed pipelines can be put into production smoothly and operate stably on schedule. The pigging operation before the pipeline is put into production and during operation is particularly important. It is one of the indispensable important equipment. [0003] According to the current domestic situation, the degree of prefabrication of pipe...
