The utility model spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, comprise that spiral wound steel wire strengthens the steel-plastic composite pipe of body, composite pipe has polymer continuum core pipe and outer composite bed, having by at least one surface has the steel wire of the adhesive structure layer that Bond or Bond and blend polymer form to do that left-handed and/or dextrorotation is wrapped in the outer surface of core pipe and the spiral wound steel wire that forms strengthens body, it is characterized in that the composite pipe end is by the core pipe, outer composite bed and spiral wound steel wire strengthen the tube wall of body composition and outwards dig formation pipe end boss, composite pipe and composite pipe firmly connect as one the pipe end boss mutually by the plastics composite flange with metal flange or metal-containing skeleton and form pipe network, can adopt the heating pipe end to form boss in the composite pipe end in conjunction with machinery type, adopt the mechanical connection method to connect steel-plastic composite pipe with metal flange, metal flange comprises that with two pipe end boss the steel wire of pipe end closely pushes down, firmly connect mutually, like this, composite pipe in use, because internal pipe pressure effect, when composite pipe is outwards expanded, the steel wire of stretchy pipe end does not inwardly shrink, steel wire strengthens physical efficiency and securely compound tube core pipe is tightly retrained, strengthened the humidification of steel wire enhancing body widely, the anti-pressure ability of composite pipe has also improved nearly one times thereupon widely, particularly these characteristics are particularly outstanding when carrying hot fluid medium, enlarged the steel-plastic composite pipe using scope of spiral wound steel wire enhancing body.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, and the metal caul that strengthens impacting force is arranged between the pipe end boss face between composite pipe and the composite pipe.Metal caul combines with metal flange, more can tightly the steel wire in the pipe end boss be clamped, and the steel-plastic composite pipe pipe network just can bear higher pressure like this.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, and there is rough groove or the sags and crests that increases surface friction drag and impacting force on the metal caul surface.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, after composite pipe and the composite pipe end face by the pipe end boss interconnected, with the plastics composite flange of metal flange or metal-containing skeleton two pipe end boss are firmly connected as one mutually then and form pipe network, can earlier the mutual heat fusing of end face be connected, strengthen the intensity and the sealability of pipeline junction.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, and the plastics composite flange of metal flange or metal-containing skeleton can put on composite pipe before the pipe end boss of making composite pipe in advance.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, and the plastics composite flange of metal flange or metal-containing skeleton is two and semi-circular two mutual clips of pipe end boss is connected.
Above-mentioned spiral wound steel wire strengthens the steel-plastic composite pipe pipe network of body, and fluted or boss on the end face of the plastics composite flange of metal flange or metal-containing skeleton accompanies seal ring between the flange.
The utility model steel-plastic composite pipe pipe network has adopted the pipe end boss, can when making metal compounded pipe, factory directly pipe end boss and piping flange be made, very convenient when making site operation, composite pipe is connected firmly, seam crossing mechanical strength height, the long service life of no leakage, pipeline or pipe coupling has improved the anti-pressure ability of composite pipe.
