Description
Technical field
The utility model relates to field of chemical equipment, particularly relates to the standoff compound thermal insulation 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 that heat at low temperature environment middle and long distance, traditional steel pipe is no longer applicable, just must use the composite steel tube with heat insulation function, at present, usually rock wool, asbestos etc.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.
The structure of thermal insulation pipe popular is in the market such: internal layer is working steel tube, and mesosphere is polyurethane insulation coating, and skin is high-density polyethylene external protective pipe.This thermal insulation pipe antiseptic property is general, is not suitable for the occasion that Environmental Conditions is more severe, as environment such as strong acid and strong bases; And need the intensity strengthening steel pipe further.
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 heat insulation effect, improves new type compound thermal insulation pipe that is wear-resisting, heat-resisting, corrosion-resistant, high strength effect.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
One one kinds of compound thermal insulation pipes with support, comprise steel pipe body (1) and are 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 support (14) one end is fixedly connected on the thermal insulation coatings layer (5) in steel pipe body (1) outside, and the other end contacts with protective layer (3) inwall; Described flange (6) have attachment hole (7) up and down;
Described insulating steel tube body (1) comprises from inside to outside successively: interior steel pipe (8), silica aerogel heat insulation layer (9), polyurethane heat insulation material (10), aluminium foil reflecting layer (11), outer steel pipe (12) and external anti-corrosion layer (13).
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.
Further, the thickness of described silica aerogel heat insulation layer (9) can be 10 ~ 50mm.
Further, external anti-corrosion layer (13) is polytetrafluoroethylene film layer, and thickness can be 5 ~ 10mm.
The utility model beneficial effect is compared with prior art:
1, the utility model 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.
2, the compound thermal insulating pipe that provides of the utility model, has silica aerogel heat insulation layer, is also filled with polyurethane heat insulation material, high insulating effect in the space between aluminium foil reflecting layer and external protective steel tube; Protect outer wall of steel pipe outside and be provided with external anti-corrosion layer, antiseptic property is excellent, long service life, and the occasion more severe in Environmental Conditions such as strong acid and strong bases is also suitable for.
3, between the thermal insulation coatings layer and protective layer of steel pipe, be provided with support, 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.
