Description
Technical field
The utility model patent relates to sea-bottom oil-gas conveying insulation pipe, specifically, relates to a kind of seabed conveying wet type thermal insulation pipeline.
Background technique
At present, the structure of the pipeline under the ocean of domestic use mainly contains " pipe-in-pipe " structure and monolayer heat-insulating pipe adds weight coating structure." pipe-in-pipe " structure and steel inner tube are used for the medium such as transferring oil, gas, and steel outer tube provides reliable protection to heat insulation layer, increases the weight of effect, are insulation (thermal insulation) layer between inner and outer pipes.The structure of single-layer heat-preserving counterbalance pipe is respectively steel pipe, anticorrosive coat, polyurethane foam insulation layer, protective polyethylene layer and concrete weighted coating from inside to outside.The electrostatic spraying of bottom anticorrosion employing clinkery epoxy powder (FBE), thermal insulation layer adopts MAH grafted polyethylene+cast polyurethane foam process, and weight coating adopts concrete spray technique.
The advantage of " pipe-in-pipe " structure is that protection reliability is high, effectively can reduce interior pipe thermal distortion; Shortcoming is outer steel pipe many employings thick walled steel tube, and steel consumption amount is large, and outer surface of steel tube needs to carry out 3 layers of polyethylene anticorrosion structure process, and corrosion-resistant expense is also higher.In addition, at sea during installation, need weld, 100% nondestructive inspection to inside and outside steel pipe, great in constructing amount, pipelaying rate is slow, and efficiency is lower, and thus integrated engineering cost is higher.
Compare " pipe-in-pipe " structure, the structure of single-layer heat-preserving counterbalance pipe adopts concrete weighted coating to substitute outer steel pipe, the steel of about 2/3rds and anticorrosion program can be saved, decrease pipe laying welding job amount, improve the speed that offshore pipeline is laid, reduce pipeline system cost, but be only applicable to shallow water area.
Model utility content
What the utility model technology will solve is that in prior art, submarine heat insulation pipeline construction work amount is large, not too be applicable to the technical problem that deep water sea area uses, there is provided a kind of rational in infrastructure, construction simply, to be not with external protection coating, be maximumly suitable for a kind of seabed conveying wet type thermal insulation pipeline that the depth of water can reach 3000m.
In order to solve the problems of the technologies described above, the utility model is achieved by following technological scheme:
Wet type thermal insulation pipeline is used in the conveying of a kind of seabed, comprise steel body, the outer surface of described steel body is followed successively by clinkery epoxy powder anticorrosive coat (FBE), polymer elastomer layer, wet type composite foam thermal insulation layer and polymer elastomer layer from the inside to surface.Described wet type composite foam thermal insulation layer is the organic resin thermal insulation layer of filling hollow glass micropearl; Described polymer elastomer layer is mainly the polymer elastomers such as polyurethane, epoxy resin, polypropylene.
The thickness of described clinkery epoxy powder anticorrosive coat (FBE) is 0.15-0.25mm.
The thickness of described wet type composite foam thermal insulation layer is 45-70mm.
The thickness of described polymer elastomer layer is 1.5-3.0mm.
The beneficial effects of the utility model are:
(1) the thermal insulation layer compressive strength of wet type thermal insulation pipeline of the present utility model is high, does not need to arrange special external protection coating, and waterproof ability is strong, and pipe laying is convenient.
(2) the utility model adopts the heat insulation coating of resin base composite foam as wet type thermal insulation pipeline of high-performance hollow glass micropearl filling, and the applicable depth of water can reach 3000m.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model describes a kind of seabed conveying wet type thermal insulation pipeline, comprise the steel body 1 of innermost layer, the outer surface of steel body 1 is coated with clinkery epoxy powder anticorrosive coat 2, polymer elastomer layer 3, wet type composite foam thermal insulation layer 4 and polymer elastomer layer 3 successively.The high-performance hollow glass micropearl particle of closed pore due to what fill in composite foam, therefore the foamed material caused due to the huge hydraulic pressure at deep-sea is avoided to break, the buoyancy preventing pipeline foam layer to cause due to water suction and the deterioration of heat-shielding performance, thus ensure that the thermal insulation property of wet type thermal insulation pipeline.If the anti-isostatic pressed intensity of the high-performance hollow glass micropearl adopted in composite foam is more than 40MPa, the applicable depth of water of corresponding wet type thermal insulation pipeline can reach 3000m.
In the present embodiment, wet type composite foam thermal insulation layer 4 is that thickness is 55mm by anti-isostatic pressed intensity is filled into more than the empty glass microballoon of the high-performance of 40MPa the cellular insulant prepared in acrylic resin; Inside and outside composite foam thermal insulation layer, the polymer elastomer layer 3 of both sides uses solid polypropylene material, and thickness is 2.5mm.
