Abstract
The utility model specifically discloses a kind of heat insulation steel pipe, comprises outer steel pipe, interior steel pipe; The outside of described outer steel pipe is furnished with thermal insulation layer and protective layer successively; The two ends cover of outer steel pipe has water-proof protection device, described water-proof protection device and thermal insulation layer and protective layer compact siro spinning technology; Described interior steel pipe socket is loaded in outer steel pipe, and the two ends of outer steel pipe are sealed by head plate and make to be formed between described two pipes vacuum heat-insulating layer, and this vacuum heat-insulating layer is communicated with airtight valve; A kind of NEW TYPE OF COMPOSITE shape steel tube can strengthening heat insulation effect is provided.
Description
Technical field
The utility model relates to field of chemical equipment, particularly relates to a kind of heat insulation steel pipe.
Background technique
Along with domestic to the increase of Demand of Oil & Gas amount, increasing oil-gas transportation changes Cemented filling into by the overland transport commonly used.Cemented filling has the advantages such as easy care, conveying cost is low, transfer efficiency is high.But to carry by heavy viscous crude oil, fuel oil or the natural gas etc. that heat at low temperature environment middle and long distance, traditional steel pipe is no longer applicable, just must use the composite steel tube with heat insulation function, at present, usually rock wool, asbestos etc. are surrounded by as thermal insulation layer in steel pipe outside, but heat insulation effect is not good, and thermal insulation layer does not have waterproofing effect, unfavorable to steel pipe.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of above background defect that solves, and strengthens the one heat insulation steel pipe of heat insulation effect.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
A kind of heat insulation steel pipe, is characterized in that: comprise outer steel pipe (1), interior steel pipe; The outside of described outer steel pipe (1) is furnished with thermal insulation layer (4) and protective layer (3) successively; The two ends cover of outer steel pipe (1) has water-proof protection device (2), described water-proof protection device (2) and thermal insulation layer (4) and protective layer (3) compact siro spinning technology;
Described interior steel pipe (6) is set in outer steel pipe (1), and the two ends of outer steel pipe (1) are sealed by head plate and make to be formed between described two pipes vacuum heat-insulating layer (7), and this vacuum heat-insulating layer (7) is communicated with airtight valve (10).
Further, described protective layer (3) is polyethylene or polypropylene.
Further, described thermal insulation layer (4) is polyurethane.
The utility model beneficial effect is compared with prior art:
Described steel pipe adopts polyurethane insulation coating, can play good function of heat insulation, is particularly useful for the long distance delivery to heavy viscous crude oil, fuel oil or the natural gas etc. that have heated under low temperature environment; Protective layer and water-tight device can carry out sealing protection to steel pipe, and anti-sealing, moisture and other multiple corrosive liquids, gas are to the corrosion of steel pipe; Due to the existence of vacuum heat-insulating layer, reduce heat transfer and thermal emissivity rate, strengthen heat insulation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the heat insulation steel pipe of one is described further.
As shown in Fig. 1, a kind of heat insulation steel pipe, is characterized in that: comprise outer steel pipe 1, interior steel pipe; The outside of described outer steel pipe 1 is furnished with thermal insulation layer 4 and protective layer 3 successively; The two ends cover of outer steel pipe 1 has water-proof protection device 2, described water-proof protection device 2 and thermal insulation layer 4 and protective layer 3 compact siro spinning technology;
Described interior steel pipe 6 is set in outer steel pipe 1, and the two ends of outer steel pipe 1 are sealed by head plate and make to be formed between described two pipes vacuum heat-insulating layer 7, and this vacuum heat-insulating layer 7 is communicated with airtight valve 10.
Further, described protective layer 3 is polyethylene or polypropylene.
Further, described thermal insulation layer 4 is polyurethane.
Description for the understanding of embodiment be only for help understand the utility model, instead of be used for restriction of the present utility model.Those skilled in the art all can utilize thought of the present utility model to carry out some and change and change, as long as its technological means does not depart from thought of the present utility model and main points, still within protection domain of the present utility model.
Claims (3)
