Problems solved by technology

[0002] A wear-resistant hose assembly for jack-up drilling platforms, semi-submersible drilling platforms, and filling station replenishment systems for drilling ships, as well as other industrial abrasive powder transportation applications. The pipe body and the hose joint need to have strong anti-pull-off and sealing functions. At the same time, the hose body must bear various external forces, such as conveying powder, external wind and waves, etc. The hose produced by the existing technology is under working pressure The deformation rate (elongation, expansion) is large under external pressure, and the powder and the tube wall will have friction and collision during the process of conveying the powder, which is easy to generate static electricity and cause an explosion

Embodiment 1

[0020] Such as figure 1 -3, a powder conveying hose assembly used in the replenishment system of the offshore drilling platform filling station according to the present invention includes a hose and a joint connected with the hose. Layer film, skeleton material layer, outer rubber layer, the joint includes an inner core sleeve and a compression sleeve, the hose is inserted into the gap formed by the inner core sleeve and the compression sleeve, and the hose is squeezed by squeezing the compression sleeve. Compression can prevent the joint from pulling out and form a sealing effect on the inner rubber. Among them, the skeleton material layer is 2 layers of nylon cord, the first layer of nylon cord is wound with a left-handed 54°44', and the second layer of nylon cord is wound with a right Rotate 54°44' winding.

[0021] The inner film is made of butadiene rubber and natural rubber as the main material, adding sulfur and sulfenamide accelerators, and super wear-resistant carbon...

Embodiment 2

[0027] The hose assembly is the same as in Embodiment 1 except for the following parts.

[0028] The skeleton material layer is 2 layers of nylon cord, the first layer of nylon cord is wound at a left-handed 45°, and the second layer of nylon cord is wound at a right-handed 62°.

[0029] The hose model SM10 manufactured by the method of this embodiment has a size of 2", an inner diameter of 51 mm, and an outer diameter of 69 mm.

Embodiment 3

[0031] The hose assembly is the same as in Embodiment 1 except for the following parts.

[0032] The skeleton material layer is 4 layers of nylon cord, the first layer of nylon cord is wound at 49° left-handed, the second layer of nylon cord is wound at right-handed 53°, the third layer of nylon cord is wound at left-handed 58°, the first layer of nylon cord is wound at right Rotate 64° to wrap.

[0033] The hose model SM10 obtained by using the method of this embodiment has a size of 3", an inner diameter of 76mm, and an outer diameter of 94mm.

Abstract

The invention discloses an abrasive powder conveying hose assembly applied to a make-up and bridging conveying system of a marine drilling platform. The abrasive powder conveying hose assembly comprises a hose and a connector connected with the hose, wherein the hose sequentially comprises an inner-layer adhesive strip, a framework material layer and an outer adhesive layer from the inside out; the framework material layer comprises a plurality of layers of nylon cord fabric or polyester cord fabric; the connector comprises an inner core sleeve and a compressed outer sleeve; the hose is inserted into a gap formed by the inner core sleeve and the compressed outer sleeve; and the compressed outer sleeve can be extruded to form extruding compression of the hose so as to perform the functions of preventing the connector from detachment and sealing the inner rubber. The invention provides the hose assembly which can transmit static electricity, has abrasion-resistant inner adhesive and is favorable in bendability and pressure-bearing performance; and meanwhile, the invention provides a manufacturing method of the hose assembly.
