Abstract
The utility model discloses a novel flange. The novel flange comprises a flange body, wherein the flange body comprises a connection layer, an outer layer and a middle layer which are fixed together to form a whole; the outer layer is an ultra-high molecular weight polyethylene layer; the connection layer is a high-intensity polyethylene layer; and the middle layer is a steel mesh. The novel flange has the beneficial effects of external pressure resistance capability and excellent welding performance, can prolong the service life and reduce the maintaining cost of pipeline engineering, is high in intensity and can bear high pressure.
Description
Technical field
The utility model relates to a kind of flange be connected with pipeline, is more particularly to a kind of novel flange for superhigh molecular weight polyethylene pipe road system, belongs to the flange field be fixedly connected with the superhigh molecular weight polyethylene pipe road.
Background technique
In superhigh molecular weight polyethylene pipe road system, superhigh molecular weight polyethylene pipe road and flange are by being welded together; Existing this flange is single layer structure at present, and made by single superhigh molecular weight polyethylene material, restriction due to material property and processing technology, general ultra-high molecular weight polyethylene flange wall thinner thickness, therefore the nominal pressure that can bear is also less, because ultrahigh molecular weight polyethylene tubing is difficult for welding, this flange and superhigh molecular weight polyethylene pipe road, by being welded together, just can not guarantee the weld bond pressure after flange welds in pipeline again.
The model utility content
The purpose of this utility model is to overcome above deficiency; Provide a kind of the critical external compressive resistance ability arranged, have superior weldability can novel flange.
A kind of novel flange, comprise flange body, and described flange body is by tie layer, skin, mesosphere, described tie layer, skin, mesosphere are fixed into one, described skin is the ultra-high molecular weight polyethylene layer, and described tie layer is high-density polyethylene layer, and described mesosphere is steel mesh.
The beneficial effects of the utility model are:
1, because skin is the ultra-high molecular weight polyethylene layer, so flange has the wear-resisting property of ultra-high molecular weight polyethylene.
2, because mesosphere is steel mesh, so can strengthen intensity of the present utility model, the pressure that the utility model can bear is large.
3, because tie layer is high-density polyethylene layer, thereby increased wall thickness, therefore strengthened the critical external compressive resistance ability of flange self; High density polyethylene (HDPE) has excellent welding performance in addition, so: the high-density polyethylene layer of the utility model tie layer and superhigh molecular weight polyethylene pipe road, by being welded together, have just guaranteed the weld bond pressure after the utility model welds in pipeline.
4, extend working life, reduced the replacing number of times of flange in pipe engineering, thereby also reduced the maintenance cost of pipe engineering.
The accompanying drawing explanation
Fig. 1 is sectional structural map of the present utility model.
Embodiment
A kind of novel flange, comprise flange body, and described flange body is by tie layer 3, skin 1, mesosphere 2, described tie layer 3, skin 1, mesosphere 2 are fixed into one, described outer 1 is the ultra-high molecular weight polyethylene layer, and described tie layer 3 is high-density polyethylene layer, and described mesosphere 2 is steel mesh.During installation, the utility model tie layer 3 and superhigh molecular weight polyethylene pipe road are by being welded together.The utility model has extended working life, has reduced the replacing number of times of flange in pipe engineering, thereby has also reduced the maintenance cost of pipe engineering.
In sum, the utlity model has the critical external compressive resistance ability, have the superior weldability energy, can increase the service life, reduce the pipe engineering maintenance cost, intensity of the present utility model is large, and the pressure that the utility model can bear is large.
