Description
Technical field
This utility model belongs to anti-corrosive steel pipe technical field, more particularly to a kind of novel anticorrosion steel pipe.
Background technology
3PE anti-corrosive steel tubes three-decker polyethylene anticorrosive coating (3PE) combines External fusion bonded epoxy coating and the poly- second of extruding
The advantageous property of two kinds of anticorrosive coats of alkene, by the interfacial characteristics and chemical-resistant characteristic of External fusion bonded epoxy coating, with extruded polyethylene
The advantages of mechanical protection properties of anticorrosive coat, combines, so as to play both strong points.Therefore as the outer of buried pipeline
Overcoat is very superior.
However, in use it has also been found that tradition 3PE anti-corrosive steel tubes have two large problems:One is gluing oxidant layer and steel pipe
With reference to imprecision, external layer preservation structure sheaf is caused to slide;Two is that external layer preservation structure sheaf is relatively thin, it is impossible to bear larger machinery punching
Hit, be susceptible to metaboly.
The content of the invention
The purpose of this utility model is to provide a kind of novel anticorrosion steel pipe, and the novel anticorrosion steel pipe is arranged outside steel pipe
Projection prevents the external layer preservation structure sheaf changing of the relative positions, and also add PVC foam layer, enhances the energy of the resistance to mechanical impact of steel pipe
Power, with high use value.
What the purpose of this utility model was realized in:A kind of novel anticorrosion steel pipe, including steel pipe, FBE,
Hose lining adhesive layer, outer gluing oxidant layer, polyethylene layer, described outer wall of steel pipe is provided with cylindrical protrusions, described outer wall of steel pipe
Spraying FBE, described FBE outside arranges hose lining adhesive layer, sets outside described hose lining adhesive layer
PVC foam layer is put, described PVC foam layer outside arranges outer gluing oxidant layer, and described the outside of outer gluing oxidant layer arranges poly- second
Alkene layer.
Described height of projection is 1mm.
Described FBE thickness is 300 μm, and described hose lining adhesive layer and outer adhesive layer thickness is 600
μm, described PVC foam thickness degree is 15mm, and described polyethylene layer thickness is 2mm.
This utility model produce beneficial effect be:A kind of novel anticorrosion steel pipe, arranges raised in the outer wall of inner layer steel pipe,
After one layer of FBE of outer wall of steel pipe even application, FBE is also presented convex shape in the high spot of steel pipe,
When hose lining adhesive layer and FBE are bonded together, contact area is increased, make what hose lining adhesive layer bondd
More firmly, being additionally, since the presence of projection can also prevent the relative slip of hose lining adhesive layer and steel pipe.This utility model exists
Polyethylene layer and hose lining adhesive layer increased one layer of PVC foam layer, and when steel pipe is subject to mechanical shock cushioning effect is played, and protect
Steel pipe, prevents pipe deformation.
Description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is cross-sectional structure schematic diagram of the present utility model.
In figure:1st, steel pipe 2, FBE 3, hose lining adhesive layer 4, PVC foam layer 5, outer gluing oxidant layer 6, poly-
Pvdf layer 7, projection.
Specific embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment 1
As shown in accompanying drawing 1-2, a kind of novel anticorrosion steel pipe, including it is steel pipe 1, FBE 2, hose lining adhesive layer 3, outer
Gluing oxidant layer 5, polyethylene layer 6, the described outer wall of steel pipe 1 is provided with cylindrical protrusions 7, the described outer wall of steel pipe 1 spraying epoxy
Powder coating 2, the described outside of FBE 2 arranges hose lining adhesive layer 3, and the described outside of hose lining adhesive layer 3 arranges PVC
Foaming layer 4, the described outside of PVC foam layer 4 arranges outer gluing oxidant layer 5, and described the outside of outer gluing oxidant layer 5 arranges polyethylene
Layer 6.
This utility model is when in use:A kind of novel anticorrosion steel pipe, in the manufacturing process of steel pipe, sets in the outer wall of steel pipe
Put the projection of cylinder;Then, in one layer of FBE of external spray of steel pipe, epoxy powder is ensured during spraying
The consistency of thickness of each position of coating, due to having projection on the outer wall of steel pipe, the FBE after spraying is also convex;
Afterwards in the outer surface bonding hose lining adhesive layer of FBE, because hose lining adhesive layer is very soft, applying with epoxy powder
After the projection contacts of layer, inner surface will form corresponding depression, increase the contact area with FBE, make hose lining
Slip phenomenon is less likely to occur adhesive layer;Then, one layer of PVC foam layer, PVC foam layer tool are set in the outside of hose lining adhesive layer
There are many gas cavernous structures, when steel pipe is clashed into, play a part of buffering, the outside of PVC foam layer arranges outer gluing
Oxidant layer;Finally, outside the outside of gluing oxidant layer arranges one polyethylene layer, and to the whole external structure of steel pipe the work of protection is played
With.
Embodiment 2
As shown in accompanying drawing 1-2, a kind of novel anticorrosion steel pipe, including it is steel pipe 1, FBE 2, hose lining adhesive layer 3, outer
Gluing oxidant layer 5, polyethylene layer 6, the described outer wall of steel pipe 1 is provided with cylindrical protrusions 7, the described outer wall of steel pipe 1 spraying epoxy
