Abstract
The utility model specifically discloses a kind of NEW TYPE OF COMPOSITE shape steel tube, comprises steel pipe body and the flange being positioned at steel pipe body two ends; 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 flange have attachment hole up and down; 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 a kind of NEW TYPE OF COMPOSITE shape steel tube.
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 that heat at low temperature environment middle and long distance, traditional steel pipe is no longer applicable, just must use the composite steel tube with heat insulation function, at present, usually rock wool, asbestos etc.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 of solving, and strengthens the NEW TYPE OF COMPOSITE shape steel tube of heat insulation effect.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
A kind of NEW TYPE OF COMPOSITE shape steel tube, comprises steel pipe body (1) and is positioned at the flange (6) at steel pipe body (1) two ends; 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 flange (6) have attachment hole up and down.
Further, described protective layer (3) is polyethylene or polypropylene.
Further, described thermal insulation layer (4) is polyurethane.
Further, described thermal insulation coatings layer (5) is composition silicate.
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, can strengthen heat insulation effect further, reach energy-conservation object, utilizes Flange joint steel pipe to ensure the sealing effect of steel pipe simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, a kind of NEW TYPE OF COMPOSITE shape steel tube is described further.
As shown in Fig. 1; a kind of NEW TYPE OF COMPOSITE shape steel tube; comprise steel pipe body 1, thermal insulation coatings layer 5, polyurethane insulation coating 4 and protective layer 3 from inside to outside successively; the two ends cover of steel pipe matrix 1 has tarpaulin; wherein 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.Wherein, described protective layer 3 is polyethylene or polypropylene, and described thermal insulation layer 4 is polyurethane, and described thermal insulation coatings layer 5 can be composition silicate.
Utilize the further joint steel pipe of flange simultaneously, ensure the sealing effect between steel pipe.
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.
