Embodiment 1

[0028] like figure 1 As shown, a pile flushing hose assembly for conveying high-pressure seawater in the pile flushing system of the self-elevating drilling platform of the present invention, the hose is sequentially composed of the inner film 1, the buffer tape layer 2, the second One layer of medium rubber layer 3, the first layer of steel wire rope 4, the second layer of medium rubber layer 5, the second layer of steel wire rope 6, the third layer of medium rubber layer 7, the outer protective tape layer 8 and the outer layer of film 9; wherein, the first The rubber layer 3 in the middle layer, the steel wire rope 4 in the first layer, the rubber layer 5 in the second layer, the steel wire rope 6 in the second layer and the rubber layer 7 in the third layer together form a pressure-bearing skeleton structure.

[0029] The inner film is made of nitrile rubber with an acrylonitrile content of 40%. It is made by adding neoprene, carbon black and petroleum resin in a mass ratio...

Embodiment 2

[0034] The glue used in each glue layer of the hose is the same as in Example 1.

[0035] When making a hose, the mandrel is used as a support for winding the hose on it. Before preparing the hose, the mandrel must be cleaned; prepare Leruigu 1808 release agent, and stir the release agent evenly until It is a milky white liquid. Coat a layer of prepared Leruigu 1808 release agent on the mandrel. The function of the release agent is to take the mandrel out of the rubber tube smoothly after the rubber tube is prepared and shaped; Wrap the inner layer film on the outer surface, the winding should be smooth without wrinkles, and the winding should be seamless, and multiple mandrels can be used for preparation at the same time; the buffer tape layer is wound on the outside of the first inner layer film, and the buffer tape layer can be high-strength fiber For cord fabric, the buffer tape layer is wrapped at 45 degrees relative to the longitudinal axis of the mandrel, with a lap sea...

Embodiment 3

[0038] The glue used in each glue layer of the hose is the same as in Example 1.

[0039] When making hoses, mandrels are used as supports for winding rubber hoses on them. Before making hoses, the mandrels must be cleaned; prepare Leruigu 1808 release agent, and stir the release agent evenly until it becomes Milky white liquid, apply a layer of prepared Leruigu 1808 release agent on the mandrel, the function of the release agent is to take the mandrel out of the hose smoothly after the hose is prepared and shaped; on the outside of the mandrel Wrap the inner layer of film on the surface, the winding should be smooth and free of wrinkles, and the winding should be seamless. Multiple mandrels can be used for preparation at the same time; the buffer tape layer is wound on the outside of the first inner film, and the buffer tape layer can be high-strength fiber cord , the buffer tape layer is wrapped at 45 degrees relative to the longitudinal axis of the mandrel, and the lap seam...

Abstract

The invention discloses a pile-impacting flexible pipe assembly for transporting high-pressure seawater used for a self-elevating drilling platform pile-impacting system. The pile-impacting flexible pipe assembly comprises a flexible pipe and a connector connected with the flexible pipe. An inner layer adhesive piece, a buffer rubberized fabric layer, a first layer of a middle adhesive layer, a first layer of steel wire ropes, a second layer of a middle adhesive layer, a second layer of steel wire ropes, a third layer of a middle adhesive layer, an outer protection rubberized fabric layer and an outer layer adhesive piece are arranged from the inside to outside of the flexible pipe. Winding angles of the first layer of the steel wire ropes and the second layer of the steel wire ropes are 50-60 degrees and minus 50-60 degrees and the winding angles are matched in a balanced mode. An outer contractive pressure coating is squeezed by withhold equipment, so that the steel wire ropes, peeled from the flexible pipe, in the front end are squeezed. An inner core sleeve of the connector makes contact with the inner adhesive layer piece of the flexible pipe closely. The inner core sleeve of the connector and the inner adhesive layer piece of the flexible pipe are connected into a whole. The invention further provides a manufacturing method of the flexible pipe assembly. The invention aims to provide the flexible pipe assembly which is light in flexible pipe body, good in bending property, high in bearing strength, small in deformation and high in tensile strength and the preparation method thereof.

Description

technical field [0001] The invention relates to the field of rubber product preparation, in particular to a pile flushing hose assembly for conveying high-pressure seawater used in a pile flushing system of a self-elevating drilling platform and a preparation method thereof. Background technique [0002] The pile flushing hose is the high-pressure flexible connection of the seawater pipeline between the main deck of the jack-up drilling platform and the pile legs, and transports high-pressure seawater. [0003] The pile flushing hose is mainly used in the pile flushing system of the self-generating drilling platform for offshore oil drilling. After the operation of the self-generating drilling platform is completed, the pile legs need to be moved to pull out the pile boots. The silt around the boots is blown loose, making pile extraction easier. And the pipe body structure of existing pile-piercing pipes on the market is all thick and heavy steel wire structure, and structu...
