Problems solved by technology

[0002]Ocean engineering refers to new construction, reconstruction and expansion projects aimed at the development, utilization, protection and restoration of marine resources, and the main body of the project is located on the seaward side of the coastline. Pipelines are commonly used in marine engineering as the main means of transportation. However, after the laying of marine engineering pipelines, there will be problems such as leakage, and the leak point is not easy to find, which brings great inconvenience to the development and maintenance of marine engineering.

Embodiment 1

[0029] Refer Figure 1-7 As shown, the present embodiment provides a high-strength corrosion-resistant marine engineering stainless steel thick-walled tube, including stainless steel tube, stainless steel pipe body including several first stainless steel pipes 1, the first stainless steel pipe 1 ends, the second stainless steel pipe 2, The first stainless steel tube 1, the second stainless steel pipe 2 is fixedly connected to the opposite locking portion, and the first stainless steel pipe 1 is adjacent the side portion of the inner side wall, and the second stainless steel tube 2 is adjacent the side of the inner side wall. There is a third slope 204, the first inclined surface 104, the third slope 204, and the first inclined surface 104, the third slope 204 is provided with a sealing layer, and the first stainless steel pipe 1 is adjacent to the outer side wall with an annular gap 103. The second slope 203 is provided with a second slope 203, the annular woven portion, and the se...

Embodiment 2

[0043] Refer Figure 8-9 As shown, the difference between the stainless steel thick-wall tube and the embodiment of the present embodiment is only that the annular clamp 7 includes a snap ring 704, the interior wall of the snap ring 704 is opened, and the diagonal thread 705 is threaded with a wedge-shaped ring 707, wedge-shaped The ring 707 is retracted from one end of the snap ring 704 to be connected to the lock ring 706, and the wedge rings 707 is opened in the axial direction 708, and the inner wall of the wedge ring 707 is in contact with the outer wall of the sealing ring 8.

[0044] When the sealing ring 8 is fixed, the wedge ring 707 is gradually selected into the oblique thread 705, since the wedge rings 707 are opened on the wedge ring 707, the wedge ring 707 is rotated, the wedge-shaped ring 707 will extrud the seal ring 8, realize the seal The ring 8 is closely fit in the groove.

Abstract

The invention discloses a high-strength corrosion-resistant ocean engineering stainless steel thick-wall pipe which comprises a stainless steel pipe body. The stainless steel pipe body comprises a plurality of first stainless steel pipes, the ends of the first stainless steel pipes are in butt joint with second stainless steel pipes, and the outer sides of the first stainless steel pipes and the outer sides of the second stainless steel pipes are fixedly connected with butt joint locking parts. The edges, close to the inner side walls, of the first stainless steel pipes are provided with first slopes, the edges, close to the inner side walls, of the second stainless steel pipes are provided with third slopes, the first slopes are matched with the third slopes, a sealing layer is arranged between each first slope and the corresponding third slope, and the edges, close to the outer side walls, of the first stainless steel pipes are provided with annular notches. The edges, close to the outer side walls, of the second stainless steel pipes are provided with second slopes, the annular notches and the second slopes form grooves with the trapezoidal sections, sealing parts are embedded into the grooves, and a plurality of sensors are annularly arranged on the sides, close to the grooves, of the sealing parts. The installation sealing performance of the pipeline is better, meanwhile, the leakage detection capacity is achieved, and convenience is provided for maintenance of ocean engineering.

Description

Technical field [0001] The present invention relates to the field of pipeline connections, in particular, to a high strength corrosion-resistant marine engineering stainless steel thick-wall tube. Background technique [0002] Ocean engineering refers to the purpose of development, use, protection, and restoring marine resources, and the engineering subject is located in the new construction, reconstruction, expansion project of the coastline to the sea side. It is often used in the marine engineering as the main transportation tool, but the ocean engineering The pipeline will have problems such as leakage after the laying is completed, and the leakage point is not easy to find, which has great inconvenience to the development and maintenance of marine engineering. Inventive content [0003] It is an object of the present invention to provide a high-strength corrosion ocean engineering stainless steel thick-walled tube to solve the above problems, set a reasonable sealing struct...
