Problems solved by technology

[0002] For the underwater construction and laying of flexible composite pipelines, the length of the pipeline cannot be determined temporarily or the measurement in advance requires more additional costs. It is necessary to cut and connect the pipeline after determining the length during on-site laying
The end joints of traditional marine flexible composite pipelines are directly opened on the joint jacket, and then connected to the exhaust system by welding after the on-site crimping is completed; the connection between the two joints is directly welded or welded to connect the flange To connect; Welding work at the construction site will increase the workload on site and increase the cost

Embodiment Construction

[0016] Attached below Figure 1-3 , the present invention is described in detail.

[0017] Such as figure 1 As shown, it includes a loose flange 1, a joint core 2 with ring teeth on the outer surface, an exhaust valve 3, and a joint jacket 4 with ring teeth on the inner surface. The joint core 2 and the joint jacket 4 at one end are connected by threads , and then the joint core 2 and the joint jacket 4 are welded together. Through the manufacturing process, the loose flange and the joint core 2 are integrated to avoid welding connection between the loose flange and the joint core 2, which improves the safety factor and reduces the cost;

[0018] Such as figure 2 , 3 As shown, when installing, put one end of the pipeline 6 into the cavity formed by the joint core 2 and the joint jacket 4, cut off a part of the outer cladding layer 9 of the pipeline 6, and put it into the connection gasket 5. Use a crimping machine to crimp the joint core 2 and the joint jacket 4 respecti...

Abstract

The invention provides an ocean flexible composite pipeline end portion buckling-pressing connector. A manufacturing technology is used for making a loose flange and a connector core as a whole, welding connection between the loose flange and the connector core is reduced, the safety coefficient is improved, and cost is reduced.

Description

technical field [0001] The invention relates to a crimping joint, in particular to a crimping joint used at the end of an ocean flexible composite pipeline. Background technique [0002] For the underwater construction and laying of flexible composite pipelines, the length of the pipeline cannot be determined for the time being or more additional costs need to be measured in advance. It is necessary to cut and connect the pipeline after determining the length during on-site laying. The end joints of traditional marine flexible composite pipelines are directly opened on the joint jacket, and then connected to the exhaust system by welding after the on-site crimping is completed; the connection between the two joints is directly welded or welded to connect the flange To connect; Welding operations at the construction site will increase the workload on site and increase costs. [0003] It is against this background that this patent application proposes a buckle joint at the en...
