Abstract
Lined steel net polyurethane plastics outer protection tube, including heat-insulation layer and outer protection tube, lined steel stratum reticulare is set between heat-insulation layer and outer protection tube, lined steel stratum reticulare is with mild steel silk screen as strong with high density polyethylene (HDPE) as matrix, the surfaces externally and internally of lined steel stratum reticulare is respectively provided with some oblique cutting steel wires, the oblique cutting steel wire of inner surface is inserted into heat-insulation layer, and the oblique cutting steel wire of outer surface is inserted into outer protection tube.The utility model lined steel net polyurethane plastics outer protection tube intensity, hardness and excellent wear-resisting property, improve environmental stress crack resistance energy, can be used for severe cold area heat supply pipeline, improve the service life of outer protection tube.
Description
Technical field
The utility model is related to heat supply pipeline technical field, and in particular to a kind of lined steel net polyurethane plastics outer protection tube.
Background technology
With the continuous improvement of China's level of urbanization, cities and towns central heating network construction is continuously increased, insulation
Application amount of the outer protection tube in heating network is increasing, but the height that most outer protection tube pipes are used in heating network at present
Density polyethylene outer protection tube, because during long-term use or when pipeline reaches service life, outer protection tube and heat-insulation layer gradually take off
From outer protection tube is easily broken off causing outer protection tube to depart from heat-insulation layer, has a strong impact on the heat insulation effect of outer protection tube.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of lined steel net polyurethane plastics outer protection tube.
The utility model includes heat-insulation layer and outer protection tube, solve the technical scheme that its technical problem used be heat-insulation layer and
Between outer protection tube set lined steel stratum reticulare, lined steel stratum reticulare with mild steel silk screen for by force with high density polyethylene (HDPE) as matrix, lined steel net
The surfaces externally and internally of layer is respectively provided with some oblique cutting steel wires, and the oblique cutting steel wire of inner surface is inserted into heat-insulation layer, the oblique cutting of outer surface
Steel wire is inserted into outer protection tube.
The utility model lined steel stratum reticulare uses extrusion forming process, is strong phase with high-quality mild steel silk screen, poly- with high density
Ethene is matrix, by steel wire point be welded into net and plastic extrusion fill in synchronously carry out, lined steel stratum reticulare is then passed through into oblique cutting steel wire
It is connected between heat-insulation layer and outer protection tube.
The utility model lined steel net polyurethane plastics outer protection tube intensity, hardness and excellent wear-resisting property, improve environment resistant
Stress cracking performance, can be used for severe cold area heat supply pipeline, improve the service life of outer protection tube.
Brief description of the drawings
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1 heat-insulation layer, 2 outer protection tubes, 3 lined steel stratum reticulares, 4 oblique cutting steel wires in figure.
Specific embodiment
As shown in the figure：A kind of lined steel net polyurethane plastics outer protection tube, including heat-insulation layer 1 and outer protection tube 2, heat-insulation layer 1 and outer
Lined steel stratum reticulare 3 is set between pillar 2, lined steel stratum reticulare 3 with mild steel silk screen for by force with high density polyethylene (HDPE) as matrix, lined steel net
Layer 3 surfaces externally and internally be respectively provided with some oblique cutting steel wires 4, the oblique cutting steel wire of inner surface is inserted into heat-insulation layer 1, outer surface it is oblique
Slotting steel wire is inserted into outer protection tube 2.
The utility model lined steel stratum reticulare uses extrusion forming process, is strong phase with high-quality mild steel silk screen, poly- with high density
Ethene is matrix, by steel wire point be welded into net and plastic extrusion fill in synchronously carry out, lined steel stratum reticulare is then passed through into oblique cutting steel wire
It is connected between heat-insulation layer and outer protection tube.
