Description

Technical Field

[0001] The utility model relates to the technical field of flexible pipes, in particular to a reinforced flexible pipe for marine engineering. Background Art

[0002] Marine engineering refers to new construction, reconstruction and expansion projects that are aimed at developing, utilizing, protecting and restoring marine resources, and the main body of the project is located on the sea side of the coastline. It is generally believed that the main content of marine engineering can be divided into two parts: resource development technology and equipment and facility technology. Flexible pipes have the characteristics of low bending stiffness and can be permanently used to connect underwater devices and floating production systems with large-scale movements. Flexible pipes can be manufactured in large lengths and stored directly on reels or ship turntables, making them easier to transport and install. In addition, flexible pipes are more adaptable to the uneven seabed environment. Flexible pipes are indispensable equipment for the transportation of marine engineering items.

[0003] However, the flexible pipe is easily damaged by external impact, which may cause leakage of the conveyed items. In addition, the flexible pipe connection is cumbersome and not convenient for quick docking and installation.

[0004] In view of this, research and improvement are conducted on the existing problems, and a reinforced flexible pipe for marine engineering is provided. The first epoxy resin structure, the second epoxy resin structure, the stainless steel spring, the chloroprene rubber structure, and the anti-collision structure are arranged to protect the sleeve outer pipe. When the anti-collision structure is hit, it can be buffered by the stainless steel spring and the chloroprene rubber structure, thereby reducing the force applied to the sleeve outer pipe. At the same time, the impact force is buffered again by the first epoxy resin structure and the second epoxy resin structure, thereby reducing the transmission of the force to the inner pipe of the flexible pipe. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
