Abstract
The utility model relates to a heat insulation delivery pipeline which comprises a heat insulation steel pipe body (10) and a left flange (11) and a right flange (12) which are located at the left end and the right end of the heat insulation steel pipe body (10). Connection holes (13) are formed in the upper portion and the lower portion of the left flange (11) and the right flange (12) respectively. The heat insulation steel pipe body (10) comprises a glass steel pipe (1), a first steel pipe (3), a heat insulation interlayer (4) and a second steel pipe (6) which are sequentially arranged from inside to outside. A first bonding layer (2) is arranged between the glass steel pipe (1) and the first steel pipe (3), and a second bonding layer (5) is arranged between the heat insulation interlayer (4) and the second steel pipe (6). The heat insulation delivery pipeline has the advantages of abrasion resistance, heat resistance, corrosion resistance and the like, is simple in structure and reasonable in design, and has high practicability.
Description
Technical field
The utility model patent relates to a kind of heat insulation type conveyance conduit.
Background technique
Steel pipe is a kind of metallic conduit generally using both at home and abroad at present, mainly contain seamless steel pipe, steel pipes with straight, with helically welded tube etc., this class pipeline have working strength high, easy to use, but the insulation of this steel pipe, the anticorrosion poor-performing that waits, and especially easily corrosion, therefore be just easy to be subject in use external influence, thereby the practical life-span reducing, but in current improvement, conventionally adopt the mode of loading to fill between base tube and coating, the parcel poor-performing of entirety like this, install easily loosening, easily produce gap, be unfavorable for the use of pipeline.
Summary of the invention
The object of the utility model patent is to provide a kind of pipeline, thereby solves the defect in above-mentioned background technology.
This patent adopts following technical characteristics:
A kind of heat insulation type steel pipe, it is characterized in that comprising the Glass Steel Tube (1) setting gradually from inside to outside, the first steel pipe (3), heat preservation sandwich layer (4) and the second steel pipe (6), between described Glass Steel Tube (1) and the first steel pipe (3), have the first adhesive layer (2), between heat preservation sandwich layer (4) and the second steel pipe (6), have the second adhesive layer (5), the thickness of described Glass Steel Tube (1) is 5mm, the thickness of the first steel pipe (3) is 4mm, and the thickness of the second steel pipe (6) layer is 6mm.
The material of described heat preservation sandwich layer (4) is urethane foam.
The material of described the first adhesive layer (2) and the second adhesive layer (5) is PP.
Described the first steel pipe (3) is identical with the material of the second steel pipe (6).
Beneficial effect:
The utlity model has wear-resisting, heat-resisting, corrosion-resistant wait many merits, and simple in structure, reasonable in design, there is high practicability, can effectively improve the working life of whole pipeline, and the thickness of this pipeline is rationally can be effectively cost-saving and improve intensity.
