Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0025] like image 3 and Figure 4 Shown, is a kind of interwoven tensile armor layer 2 of the present invention, and it comprises inner layer tensile armor layer 2-5 and outer layer tensile armor layer 2-7, and described inner layer tensile armor layer 2-5 and the outer tensile armor layer 2-7 are interlocked and connected as one by means of orthogonal interweaving and symmetrical winding, and the inner tensile armor layer 2-5 and the outer tensile armor layer Both layers 2-7 are rotated, extended and wound at a certain helical angle in opposite clockwise and counterclockwise directions. In the present embodiment, the spiral angle is in the range of 70°, and the inner layer ten...

Abstract

The invention discloses a flexible vertical pipe and an interlaced tensile armor layer thereof. The interlaced tensile armor layer comprises an inner tensile armor layer and an outer tensile armor layer, wherein the inner tensile armor layer and the outer tensile armor layer are interlocked and connected into a whole in an interlaced symmetric winding manner; and the inner tensile armor layer andthe outer tensile armor layer respectively rotate, extend and wind at a certain spiral angle along clockwise and anticlockwise directions. The orthogonally-interlaced tensile armor layer is lower in material consumption and simple in structure, the structural strength of the orthogonally-interlaced tensile armor layer is improved on the premise of no addition of other materials, and the orthogonally-interlaced tensile armor layer has good practicability and economical efficiency.

Description

technical field [0001] The invention relates to the technical field of flexible risers in the marine field, in particular to a tensile armor layer. Background technique [0002] As the world's demand for oil and gas resources continues to increase, land and offshore exploitable resources are decreasing, and more and more attention has been paid to the development of marine resources. Although my country has rich reserves of oil and gas resources, especially in the South China Sea, which has 30 billion tons of crude oil and 16 trillion cubic meters of natural gas, due to my country's limited reserves of oil and gas resources development technology, the rich oil and gas resources in the South China Sea are being plundered by neighboring countries. Therefore , There is a long way to go to improve the research and development technology of my country's deep-sea oil and gas resource equipment. [0003] The riser system is the key structure connecting the subsea oil and gas produc...
