Abstract

The invention provides a tensile flexible pipe which comprises an internal adhesive layer, a framework layer and an external adhesive layer which are sequentially arranged from inside to outside. The tensile flexible pipe is characterized in that the framework layer comprises fiber layers and a metal spiral layer clamped between the fiber layers; the internal adhesive layer is used for conveying liquid medium and has resistance and tightness to the transported liquid medium; the framework layer is served as a supporting structure of the tensile flexible pipe for bearing the working pressure and tensile force of the tensile flexible pipe; the external adhesive layer is used for protecting the framework layer and resistant to the damage caused by the working environment of the tensile flexible pipe. With the adoption of the tensile flexible pipe, the tensile force and the anti-tension performances of the tensile flexible pipe are obviously improved, and an assistant supporting device for conventional tensile flexible pipe in work is saved, therefore, the structure of liquid cargo supplementing device can be greatly simplified, the production cost is saved, and the use is more convenient.

Description

technical field

[0001] The present invention generally relates to the field of navigation lateral replenishment, and in particular relates to a high-strength tension hose used in navigation lateral replenishment. Background technique

[0002] Since the emergence of voyage replenishment at the end of the nineteenth century, sea voyage replenishment has undergone many major improvements from single liquid cargo replenishment to comprehensive replenishment, and from vertical replenishment to horizontal and vertical replenishment. In 1944, the cross-cable method was invented for horizontal refueling. In 1953, a counterweight tension compensation device was developed. In 1957, the idea of ​​comprehensive replenishment was established, and then the automatic transfer replenishment system (FAST) appeared. In the mid-1970s, FAST began to be adopted. System improvement system - Standard Horizontal Replenishment Device (STREAM). Since the 1990s, around the need to further improve the ...
