Abstract
The utility model relates to a heat-insulating composite hose for undersea three-phase mixed conveying. The hose is characterized by comprising skeleton layers, an internal pressure sealing layer, a pressure-resistant armor layer, wear-resisting layers, tensile armor layers, an insulating layer, a middle coating layer, a counterweight protection layer and an external coating layer. By the aid of the insulating layer structure, a tube condensing phenomenon caused by rapid cooling due to heat loss of a hose body is avoided in a long-distance transmission process of oil, gas and water media, and high cost produced due to the fact that no insulating layer exists and a high-temperature resistant material is used for improving the inlet temperature can be effectively reduced.
Description
Technical field
The utility model relates to a kind of seabed composite soft tube, particularly about a kind of for thering is the composite soft tube for seabed oil, gas, water mixed delivery of heat insulation function.
Background technique
Sea multiphase pipeline traditional, routine be take steel pipe as main, whole construction, installation and the follow-up maintenance operation cycle is long, expense is high, the steel that Abroad in Recent Years rises mould composite soft tube because anticorrosive property is good, submarine topography landforms strong adaptability, laying speed is fast, expense is low, be difficult for wax deposition and the conveying that advantage starts to be applied to seabed oil, G&W such as can reuse comes up.But external sea multiphase pipeline complex structure and installation cost are higher, the later maintenance cycle is long, and expense is high, and domestic flexible pipe is still in the starting stage, product function and structure are more single, have just started to be applied in the oil transportation that water delivery, gas transmission and conveying solidifying point are higher.Along with the exploitation of deepwater field, medium composition to be conveyed and applying working condition complexity more, when the solidifying point of fed sheet of a media is lower, need to consider the thermal insulation property of pipeline when fed distance is long, there will not be " solidifying pipe " phenomenon when guaranteeing to arrive feeding terminal.If do not adopt the flexible pipe with insulating structure, can only significantly improve the temperature of pipeline entrance, cause flexible pipe non-metallic layer to adopt the higher material of heat resistance, thereby increase raw-material buying expenses and significantly improve auxiliary facility maintenance cost.
Present patent application has proposed seabed insulation three-phase mixed transferring composite soft tube just under this background.
Model utility content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of seabed to be incubated three-phase mixed transferring composite soft tube, passing through be provided with heat insulation layer structure realization oil, gas, aqueous medium is growing apart from course of conveying, the solidifying pipe phenomenon that reduction causes quick temperature drop to cause due to the thermal loss of body, and can effectively reduce because not having thermal insulation layer to improve inlet temperature, use the high cost that exotic material produces instead.
The purpose of this utility model is realized by following technological scheme:
Seabed insulation three-phase mixed transferring composite soft tube, it is characterized in that: be provided with framework layer, inner pressuring sealing layer, resistance to compression armor, wearing layer, tension armor, thermal insulation layer, tundish coating, counterweight protective layer, external coating forms, wherein framework layer is positioned at hose body inside, by the special-shaped stainless steel interlocking of S type, formed, inner pressuring sealing layer is between framework layer and resistance to compression armor, inner pressuring sealing layer pushes cooling forming by thermoplastic, resistance to compression armor is Wrapping formed by the positive and negative bidirectional screw of resistance to compression steel band, wearing layer is between resistance to compression armor and tension armor, wearing layer is Wrapping formed by banded wear-resistant strip, tension armor is Wrapping formed by the positive and negative bidirectional screw of tension band steel, thermal insulation layer is between tension armor and tundish coating, the banded structure that thermal insulation layer is dispersed in polypropylene matrix as discrete particles by vacuum glass microballon is helically-wound shaped, tundish coating pushes cooling forming by thermoplastic, counterweight protective layer is between tundish coating and external coating, counterweight protective layer is Wrapping formed by the positive and negative bidirectional screw of resistance to compression steel band, external coating is by pushing cooling forming by thermoplastic.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, passing through be provided with heat insulation layer structure realization oil, gas, aqueous medium is growing apart from course of conveying, the solidifying pipe phenomenon that reduction causes quick temperature drop to cause due to the thermal loss of body, and can effectively reduce because not having thermal insulation layer to improve inlet temperature, use the high cost that exotic material produces instead.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation:
Fig. 1 is hose construction schematic diagram.
Major label description in figure:
1-framework layer; 2-inner pressuring sealing layer; 3-resistance to compression armor; 4-wearing layer; 5-tension armor; 6-thermal insulation layer; 7-tundish coating; 8-counterweight protective layer; 9-external coating.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in detail.
As shown in Figure 1, framework layer 1 becomes S type interlocking structure by stainless steel belt by locking machine rolling, inner supporting structure as composite soft tube, after framework layer 1 completes, be transported to coated extruder and extrude the thermoplastic of 5mm-12mm thickness, complete the production of inner pressuring sealing layer 2, be transported to the production line of steel band resistance to compression armor, by steel strip winding equipment thickness 0.6mm-1.3mm, the ribbon spiral of width 50mm-80mm is wound to outside inner pressuring sealing layer 2, general steel band adopts positive and negative two-way winding, being wound around the number of plies determines according to indoor design pressure, completing resistance to compression armor 3 produces, the attached winding machine of equipment directly completes the production of wearing layer 4, be transported to the production line of band steel tension armor, by band steel Wiring apparatus thickness 2mm-5mm, the band steel of width 6mm-12mm is spirally wound on the external diameter of wearing layer 4 according to technological requirement, completing tension armor 5 produces, the attached winding machine of equipment is directly wound around one deck wearing layer 4 again, thermal insulation layer 6 is spirally wound on tension armor 5 external diameters by special-purpose lapping equipment, the thickness being wound around is by temperature drop Analysis deterrmination, winding angle need to meet the technological requirement of bending radius and production, and porosity ratio is unsuitable excessive, tundish coating 7, external coating 9 is produced according to the production technology of inner pressuring sealing layer 2, counterweight protective layer 8 is produced according to the production technology of resistance to compression armor 3, complete the production of flexible pipe.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
