Abstract
The utility model discloses a kind of wear-resistant composite pipe in pipe technology field, including the inner tube being made up of anticorrosion antiwear material, also include be socketed in inner tube periphery and with the Justified high intensity outer tube of inner tube, also include the adding layers for being arranged between inner tube and outer tube and merging inner tube with outer tube, in addition to be welded on the pipe end outer peripheral face of outer tube, the flange for being connected between pipeline；The end face of the flange and the end face of outer tube；The adding layers are made up of high polymer material and with decrease of noise functions.The utility model corrosion protection abrasion resistant, service life is long.
Description
Technical field
The utility model is related to pipe technology field, more particularly to a kind of wear-resistant composite pipe.
Background technology
Bend pipe, three-way pipe, reducer pipe are one of indispensable pipe fittings, are wide variety of originals substantially in pipeline connection
Part.Traditional bend pipe, three-way pipe, reducer pipe typically use the high intensity carbon steel or corrosion resistant steel alloy of single material, carbon steel
Although cost is low but anticorrosion antiwear poor performance, although and the steel alloy anticorrosion antiwear performance of anticorrosion antiwear is good, cost is high and difficult
To meet its mechanical property requirements.Simultaneously for industries such as coal-burning power plant, mine, metallurgy, chemical industry, contain coal dust, coal in conveying
It is right because working condition is more severe when the graininess gas-solids such as slag, dry ash, ore pulp, firm slag, sandstone material, solidliquid mixture medium
Wash away more serious in the abrasion of pipeline, service life is low.
Utility model content
The purpose of this utility model is to provide a kind of wear-resistant composite pipe of service life length.
What the purpose of this utility model was realized in：A kind of wear-resistant composite pipe, including be made up of anticorrosion antiwear material
Inner tube, in addition to be socketed in inner tube periphery and with the Justified high intensity outer tube of inner tube, in addition to be arranged on inner tube with
The adding layers merged between outer tube and by inner tube with outer tube, in addition to be welded on outer tube pipe end outer peripheral face, for pipeline it
Between the flange that connects；The end face of the flange and the end face of outer tube；The adding layers are made and had by high polymer material
There is decrease of noise functions.
Compared with prior art, the beneficial effects of the utility model are：Due to inner tube, the setting of outer tube, bearing capacity
Greatly, wear resistant corrosion resistant, when transporting granular gas-solid, solidliquid mixture medium, weares and teares small, service life is long；Due to adding layers
Set, the outer tube sleeve after Overheating Treatment is mounted in the inner tube periphery through Overheating Treatment, then by adding layers by inner tube, outer tube
Fusion, not only acts as the function of noise reduction, while enhancing wear-corrosion resistance；Because flange welding is in the periphery of outer tube pipe end
Face, and the end face and the end face of outer tube of flange, will not be to method in transporting granular gas-solid, solidliquid mixture medium
Orchid causes abrasion, and service life is long.
As preferred scheme of the present utility model, there is gap between said inner tube, outer tube, poured after the adding layers melting
Cast in the gap between inner tube, outer tube.
As further preferred scheme of the present utility model, said inner tube is high alloy steel pipe.
As further preferred scheme of the present utility model, the outer tube is seamless steel pipe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 flange, 2 outer tubes, 3 inner tubes, 4 adding layers.
Embodiment
As shown in figure 1, a kind of wear-resistant composite pipe, including the inner tube 3 being made up of anticorrosion antiwear material, in addition to be socketed in
The periphery of inner tube 3 and with the Justified high intensity outer tube 2 of inner tube 3, in addition to be arranged between inner tube 3 and outer tube 2 and
The adding layers 4 that inner tube 3 is merged with outer tube 2, in addition to it is welded on the pipe end outer peripheral face of outer tube 2, for what is connected between pipeline
Flange 1；The end face of flange 1 and the end face of outer tube 2；Adding layers 4 are made up of high polymer material and with decrease of noise functions.
There is gap between above-mentioned inner tube 3, outer tube 2, adding layers 4 cast in the gap between inner tube 3, outer tube 2 after melting
It is interior.
Above-mentioned inner tube 3 is high alloy steel pipe.
Above-mentioned outer tube 2 is seamless steel pipe.
Operation principle of the present utility model is described below, first, and the inner tube 3 cast is quenched, be stripped, cooled down,
Meanwhile, the outer tube 2 cast is quenched, be stripped, cooled down, then outer tube 2 is sleeved on to the periphery of inner tube 3, two ends are flushed；
Now, the gap high polymer material of melting cast between inner tube 3, outer tube 2, is then cooled down so that inner tube 3, outer tube 2 melt
Unify body；Finally, flange 1 is set with and is welded on the periphery of the pipe end of outer tube 2, while the end face of the end face of flange 1 and outer tube 2 is neat
It is flat.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour just can be special to some of which technology
Levy and make some replacements and deform, these are replaced and deformed in protection domain of the present utility model.
