Description
Technical field
The utility model patent relates to a kind of corrosion resistant type steel pipe.
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 corrosion resistant 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), the second steel pipe (6) and high density polyethylene (HDPE) outer tube (8), between described Glass Steel Tube (1) and the first steel pipe (3), there is the first adhesive layer (2), between heat preservation sandwich layer (4) and the second steel pipe (6), there is the second adhesive layer (5), the internal layer of described Glass Steel Tube (1) also has corrosion-inhibiting coating (7), the thickness of described Glass Steel Tube (1) is 4mm, the thickness of the first steel pipe (3) is 4mm, the thickness of the second steel pipe (6) layer is 5mm, the thickness of high density polyethylene (HDPE) outer tube (8) is 2mm.
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.
Brief description of the drawings
Fig. 1 is the sectional view of this patent.
