Description

The standoff new type compound Glass Steel Tube of a kind of band
Technical field
The utility model relates to field of chemical equipment, particularly relates to the standoff new type compound Glass Steel Tube 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 that heat at low temperature environment middle and long distance, traditional steel pipe is no longer applicable, just must use the composite steel tube with heat insulation function, at present, usually rock wool, asbestos etc.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.
Simultaneously, steel pipe is a kind of metallic conduit generally used both at home and abroad at present, mainly contain seamless steel pipe, steel pipes with straight, with helically welded tube etc., this kind of pipeline have working strength high, easy to use, but the insulation of this steel pipe, anticorrosion poor-performing such as grade, and especially easily corrode, therefore be just easy in use be subject to external influence, thus the life-span of the practicality reduced, but in current improvement, usually adopt the mode loaded to fill between base tube and coating, the parcel poor-performing of such entirety, install and easily loosen, easy generation gap, be unfavorable for the use of pipeline, 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, and the one improving wear-resisting, heat-resisting, anticorrosion effect and steel pipe integral intensity is with standoff new type compound Glass Steel Tube.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
The standoff new type compound Glass Steel Tube of a kind of band, 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 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 up and down;
Described steel pipe body (1) comprises from inside to outside successively: Glass Steel Tube (8), inner side steel pipe (10) and outside steel pipe (13); There is between described Glass Steel Tube (8) and inner side steel pipe (10) inner adhesion layer (9), there is between heat preservation sandwich layer (11) and outside steel pipe (13) outboard bonds layer (12).
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, described heat preservation sandwich layer (11) is urethane foam.
Further, described inner adhesion layer (9) and outboard bonds layer (12) are PP.
The utility model beneficial effect is compared with prior art:
1, 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.
2, the utility model has the many merits such as wear-resisting, heat-resisting, corrosion-resistant, and structure is simple, reasonable in design, has high practicability, effectively can improve the working life of whole pipeline, and the thickness of this pipeline rationally can effectively cost-saving and improve intensity.
3, between steel pipe and protective layer, be provided with support, both can have played and protect steel pipe and protective layer to be the same center of circle, body bulk strength can have been strengthened again.
