Problems solved by technology

[0003] In the above-mentioned traditional flange underwater pipeline maintenance, the pipeline maintenance technology has the following technical problems, that is, after the underwater welding flange and the centering of the flange, it is difficult to measure the distance accuracy between the flanges, which affects the traditional technology. The butt joint installation of the flange, or the pup joint is too long to install, or there is a gap after the pup joint is installed, which will affect the sealing effect of the pup joint after butt joint, especially for the maintenance of some large underwater pipelines, the installation failure caused Cost losses are particularly substantial

Embodiment Construction

[0130] For ease of understanding, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0131] see Figure 1 to Figure 7 , an underwater adjustable pipeline connection device according to an embodiment of the present invention, which includes a connecting pipe 1 , a telescoping pipe 2 , a fastening device 3 and two sealing devices 4 .

[0132] The first end of the connecting pipe 1 is a flange joint for connecting with one end of the connected pipe (for example, it may be a welded flange of an underwater pipe after cutting);

[0133] The second end of the connecting pipe 1 is used as the support body of the fastening device 3, and the end surface is provided with several threaded holes, wherein a circle of screw rod 36 and a nut 35 are installed, and the tightening activity of the fastening device 3 (for example, by rotating the nut 35) is The entire pipe connection device provides a tight and sealing driving force;

Abstract

The invention relates to an adjustable pipe connection device. The adjustable pipe connection device comprises a connecting pipe, an extensible pipe, a fastening device and a sealing device; the fastening device comprises an end cover, a screw, a nut, a driving ring, a snap ring, a supporting base and a push rod; the sealing device comprises a sealing ring and an extruding ring. According to the adjustable pipe connection device, the driving force which is provided for the fastening device and used for performing radial locking is converted into the pushing force which is transmitted to the sealing device and used for performing sealing after a certain extent of locking to implement the linkage matching of the fastening and sealing and accordingly the technical effect of the locking and sealing can be simultaneously implemented under the action of the single force to enable the technical effect of the locking and sealing to be successively or simultaneously achieved only through the continuous corresponding force and accordingly the operation of the locking and sealing is simple and convenient, the adjustable pipe connection device is particularly suitable for the abutting joint of connectors comprising flange short sections during underwater pipe maintenance, a welding flange after pipe cutting of the underwater pipe maintenance does not need to be accurately measured, and the connector abutting joint is short in sealing time and good in sealing effect.

Description

technical field [0001] The invention relates to maintenance of underwater rigid oil and gas pipelines, in particular to an underwater adjustable pipeline connection device. Background technique [0002] For the maintenance of underwater oil and gas pipelines, especially for the maintenance of underwater rigid oil and gas pipelines, the usual method is to cut off the damaged section of the pipeline and connect the new pipeline. The existing underwater rigid pipeline maintenance methods include mechanical connector maintenance and flange underwater maintenance. The mechanical connector maintenance method requires that the treated underwater pipeline has a better surface finish to meet the sealing performance requirements after the connector is connected. ; For flange underwater maintenance, the method is to weld and connect the flange at the end of the cut pipe, and then install the flange sub-joint underwater, so that the flange sub-joint and the welded flange of the pipe are...
