Abstract
The utility model specifically discloses the standoff steel pipe of a kind of band, and comprise steel pipe body, the outside of described steel pipe body is furnished with thermal insulation coatings layer, thermal insulation layer and protective layer successively; The two ends cover of steel pipe body has water-proof protection device, described water-proof protection device and thermal insulation coatings layer, thermal insulation layer and protective layer compact siro spinning technology; 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; Thermal insulation coatings layer has heat reflection, feature that thermal conductivity is low, can strengthen heat insulation effect further.
Description
Technical field
The utility model relates to field of chemical equipment, particularly relates to the standoff steel pipe of a kind of band.
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 that heat at low temperature environment middle and long distance, traditional steel pipe is no longer applicable, just must use the composite steel tube with heat insulation function, at present, usually be surrounded by rock wool, asbestos etc. as thermal insulation layer in steel pipe outside, but heat insulation effect is not good, and thermal insulation layer do not have waterproofing effect, unfavorable to steel pipe, and need the bulk strength strengthening steel pipe.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of above background defect of solving, strengthen heat insulation effect and steel pipe integral intensity one be with standoff steel pipe.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
The standoff steel pipe of a kind of band, comprise steel pipe body (1), the outside of described steel pipe body (1) is furnished with thermal insulation coatings layer (5), thermal insulation layer (4) and protective layer (3) successively; The two ends cover of steel pipe body (1) has water-proof protection device (2), described water-proof protection device (2) and thermal insulation coatings layer (5), thermal insulation layer (4) and protective layer (3) compact siro spinning technology; Described support (6) one end is fixedly connected on steel pipe body (1) outside thermal insulation coatings layer (5), and the other end contacts with protective layer (3) inwall.
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; Thermal insulation coatings layer has heat reflection, feature that thermal conductivity is low; heat insulation effect can be strengthened further; reach energy-conservation object; support is provided with between the thermal insulation coatings layer and protective layer of steel pipe; both can play protection steel pipe, thermal insulation coatings layer and protective layer is the same center of circle, can strengthen body bulk strength again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Standoff steel pipe is with to be described further below in conjunction with drawings and Examples to one.
As shown in Fig. 1, the standoff steel pipe of a kind of band, comprise steel pipe body 1, the outside of described steel pipe body 1 is furnished with thermal insulation coatings layer 5, thermal insulation layer 4 and protective layer 3 successively; The two ends cover of steel pipe body 1 has water-proof protection device 2, described water-proof protection device 2 and thermal insulation coatings layer 5, thermal insulation layer 4 and protective layer 3 compact siro spinning technology; Described support 6 one end is fixedly connected on outside steel pipe body 1 on thermal insulation coatings layer 5, and the other end contacts with protective layer 3 inwall.
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)
