Abstract
The utility model relates to a metallic and plastic composite anticorrosive pipe, belonging to building and construction materials in the field of water supply and sewerage works. The inner and the outer wall of a metal pipe are adpressed by plastic in order to form the metallic and plastic composite anticorrosive pipe. Compared with a metal pipe, the utility model has anticorrosive function and needs no paint; compared with a pure plastic pipe, the utility model has the strength of the metal pipe and has aging resistance. The utility model is an optimal anticorrosive pipe material for water supply, gas supply, petroleum and chemical industries, and can play cleaning effect on tap water.
Description
The metallo-plastic composite anti-corrosive pipe that the utility model relates to a kind of building, building materials, gives, draining is used.
Existing galvanized pipe gets rusty easily, anti-corrosion capacity is poor, must influence water quality often to its paint maintenance.The plastic overmold pipe of iron pipe does not get rusty easily the not anticorrosive water quality that influences yet in the outer plastics because of internal layer has plastic tube.
The purpose of this utility model overcomes above-mentioned not enough outer compound with the different colours plastics, and is not only elegant in appearance but also solved units concerned such as chemical industry, chemical fertilizer, electric power and need use color differentiating because of pipe, and the trouble that avoids painting.The inner plastic lining can be prevented the corrosion to tube wall such as sealing, gas, corrosion liquid, purifies water nontoxic a kind of NEW TYPE OF COMPOSITE tubing.
Below in conjunction with Figure of description the utility model is described in detail:
Accompanying drawing is a metallo-plastic composite anti-corrosive pipe cut-away view of the present utility model.
It can select metal pipes such as different size aluminum pipe, steel pipe, welded pipe, seamless steel pipe for use by plastic liner (1), metal tube (2), outer plastic overmold pipe (3), metal tube (2) the utility model, carry out antirust, gluing earlier, carry out plastics and metal tube (2) external diameter compound with the pipe plastic composite mould through extruder.Select external diameter to pierce in the metal tube (2) then less than the plastic tube of metal tube (2) internal diameter, with end sealing, the other end connects high pressure high temperature vapor with its plastic liner (1) pressurization of heating, and its plastic liner (1) is expanded, be close to metal tube (2) inwall, compound once more.The composition metal plastics anti-corrosion pipe of an inner plastic bushing pipe (1), middle level metal tube (2), the outer cage walls (3) of plastics is finished.
The utility model metallo-plastic composite anti-corrosive pipe, it is big that comparison polyvinyl chloride hard pipe has intensity, not flexible modification, anti-aging, compression resistance is difficult for breaking.The comparison metal tube has corrosion-resistant, and long service life is easy to connect, and it is anticorrosion to brush paint.Be a kind of clean water, anticorrosion, easy processing, both artistic and practical novel tube.
The utlity model has that to have more hardness than prior art PVC hard tube big, be difficult for breaking because of there is metal tube (2) lining in the middle level, compression resistance, not flexible modification, anti-aging.Prior art galvanized iron conduit relatively, because of in have plastic liner (1) to have more anticorrosion, acid-proof, nontoxic effect, play the effect that purifies water.Pipe is straight-through with plastics, threeway, size connect etc. directly engages with glue, and jointing intensity is big, and it is antirust that the pipe outer wall need not be brushed paint, has easy construction, and the saving of labor saves time, a kind of novel tube of material-saving practicality.
Claims (1)
1, a kind of metallo-plastic composite anti-corrosive pipe, its feature is made of plastic inner lining pipe (1), the outer plastic overmold pipe of metal tube (2) (3), undertaken plastics and metal tube (2) compound with extruder by the pipe plastic composite mould, the plastic tube that interior then plastic liner (1) is extruded with extruder is less than metal tube (2) inwall, fits inside with the high-temperature vapour pressurization to make plastic liner (1) be close to the inwall of metal tube (2).
