Abstract
A modified two-layer epoxy powder anti-corrosion pipe solves the problems of the current anti-corrosion pipe, such as poor anti-corrosion, poor temperature resistance, environment pollution, high cost, short service life and narrow application. The utility model is characterized in that: the outer wall of a mental pipe (1) is provided with an inner anti-corrosion layer (3) and an outer anti-corrosion layer (2) made of modified epoxy resin powder; the surfaces of the inner anti-corrosion layer (3) and the outer anti-corrosion layer (2) are respectively provided with an inner protective layer (5) and an outer protective layer (4) that are made of modified epoxy resin powder; the mental pipe (1) arranged at the lateral ends of the outer anti-corrosion layer (2) and the outer protective layer (4) is coated with a coating (6). The utility model has the advantages of good anti-corrosion, low cost, long service life, no pollution, temperature resistance and wide application.
Description
Technical field:
The utility model relates to oil field and used a kind of anti-corrosion pipe, especially the modification dual-layer epoxy powder anti-corrosion pipe of urban construction construction.
Background technique:
The tens thousand of kilometers of the annual various pipelines of laying of oil field and urban construction, most anti-corrosion pipe adopts the asphalt anti-corrosion pipe, three layers of PE anti-corrosion pipe, epoxy resin coating antiseptic pipe, the asphalt anti-corrosion pipe, when hot weather construction, be subjected to the easy deformation that influences of high temperature, even trickling, easy embrittlement during low temperature, make the anticorrosive coat fragmentation, thereby reduce and lose antiseptic property pipe, moreover the medium temperature that this pipe is carried is low, generally is no more than 50 ℃, in addition, the antibacterium corrosion and the anti-plant roots and stems penetrating power of anticorrosive coat are relatively poor, inapplicable in the marsh, the area, farmland, using scope is restricted, production and processing and complex structure, seriously polluted, difficult quality reaches design standard and requirement; Three layers of PE anti-corrosion pipe complex structure, complex manufacturing are built a production line and are invested more than 1,000 ten thousand yuan, exist cathode screen to be difficult to realize cathodic protection, and the quality of production is difficult to control, cost of production height; There is the water absorption rate height in epoxy resin coating antiseptic pipe, and anti-mechanical shock, anti-machinery scratch poor performance, and construction and carrying anticorrosive coat are fragile, have a strong impact on antiseptic effect, has reduced pipeline working life.
Summary of the invention
Existing anti-corrosion pipe antiseptic property is poor, heatproof is poor in order to overcome, befouling environment, cost height, working life is short, application area is narrow deficiency, the utility model provides a kind of modification dual-layer epoxy powder anti-corrosion pipe, and this modification dual-layer epoxy powder anti-corrosion pipe has that antiseptic property is good, cost is low, long service life, pollution-free, heatproof, the wide characteristics of application area.
The technological scheme that the utility model is taked is: this modification dual-layer epoxy powder anti-corrosion pipe comprises metal tube, be equipped with interior anticorrosive coat and the external anti-corrosion layer that material is the modified epoxy powder respectively at the inside and outside wall of metal tube, interior anticorrosive coat and external anti-corrosion layer surface are equipped with interior protective coating and the external protection coating that material is the modified epoxy powder respectively, on the metal tube of the two side ends of external anti-corrosion layer and external protection coating coating are arranged.
Scribble on the above-mentioned coating and can weld coating.
The utlity model has following beneficial effect, owing to take the modification anticorrosive coat at the inner and outer surface of metal tube of such scheme bonding firm with metal, antiseptic property is good, on the modified epoxy anticorrosive coat on the inner and outer surface, have not only with the modified epoxy anticorrosive coat bonding firmly but also the protective coating of shock resistance, good insulation preformance, it is anticorrosion that the metal tube inner and outer surface is obtained, has the intensity height, shock-resistant again and mechanical scuffing, serviceability temperature can reach 120 ℃, and production technology is simple, cost is low, production is pollution-free, applied widely.
Description of drawings:
Accompanying drawing 1 is a partial sectional view of the present utility model.
1-metal tube among the figure, anticorrosive coat in the 2-external anti-corrosion layer, 3-, protective coating in the 4-external protection coating, 5-, 6-coating.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in FIG., this modification dual-layer epoxy powder anti-corrosion pipe comprises metal tube 1, be equipped with interior anticorrosive coat 3 and the external anti-corrosion layer 2 that material is the modified epoxy powder respectively at metal tube 1 inside and outside wall, interior anticorrosive coat 3 and external anti-corrosion layer 2 surfaces are equipped with interior protective coating 5 and the external protection coating 4 that material is the modified epoxy powder respectively, on the metal tube 1 of the two side ends of external anti-corrosion layer 2 and external protection coating 4 coating 6 are arranged.In the metal tube 1, anticorrosive coat 3 and external anti-corrosion layer 2 are bonding firm with metal 1 in the modification of outer surface, antiseptic property is good, on the surface of interior anticorrosive coat 3 and external anti-corrosion layer 2, have bonding with it firm again, shock resistance again, the interior protective coating 5 of good insulation preformance and external protection coating 4, make metal tube 1 inner and outer surface obtain anticorrosion, has the intensity height, shock-resistant again and mechanical scuffing, this material epoxy resin and other resin, exotic material and additive mix after the melting modification, gel and solidification process be coated in behind the tube surface in can be divided into voluntarily, external anti-corrosion layer (3,2) and in, external protection coating (5,4), production technology is simple, and is identical with the price of pitch anti-corrosion pipe, cost is low, produce pollution-free, has anti-bacterial corrosion, anti-plant roots and stems penetrates, shock resistance, anti-mechanical scuffing ability is strong, and anticathode protects unshielded effect, serviceability temperature can reach 120 ℃, application area is wide again, and the life-span can construct under harsh conditions and use in 50 years; Scribble on the two ends coating 6 of anti-corrosion pipe and can weld coating, can remove the rust cleaning of on-the-spot weld bond and repaired mouth from, do not influence welding.
Claims (2)
1, a kind of modification dual-layer epoxy powder anti-corrosion pipe, comprise metal tube (1), it is characterized in that: be equipped with interior anticorrosive coat (3) and the external anti-corrosion layer (2) that material is the modified epoxy powder respectively at the inside and outside wall of metal tube (1), interior anticorrosive coat (3) and external anti-corrosion layer (2) surface are equipped with interior protective coating (5) and the external protection coating (4) that material is the modified epoxy powder respectively, on the metal tube (1) of the two side ends of external anti-corrosion layer (2) and external protection coating (4) coating (6) are arranged.
