Abstract
The present utility model discloses a kind of HDPE-PP composite winding reinforced pipe in pipe technology field.By the tubing of the composite strip spiral winding welding with stiffening rib, it is characterized in that: the stiffening rib on described composite strip is PP bellows, PE material and PP bellows are mixed and made into semi-finished product by extruder by composite strip, there is symmetrical fusion molding junction plane composite strip both sides, Stetch Wrapping Machine is wound around composite strip in a spiral manner and fuses into tubing body at junction plane overlap joint melten gel, tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding hollow boss stiffening rib thereon, and hollow reinforced rib is perpendicular to tube wall.The utility model has good ring stiffness and face of weld heat seal strength advantages of higher.
Description
Technical field
The utility model belongs to a kind of HDPE-PP composite winding reinforced pipe relating to pipe technology field.
Background technique
In urban construction, subsoil drain and burying underground of drain pipe are important municipal engineering, existing pressure piping generally is polythene material, because poly compressive resistance is poor, if reach certain anti-pressure ability, then tube wall will be thickeied, or steel band is added in tube wall, the weight of body is made greatly to increase like this, cost of production also increases, therefore, be necessary to provide a kind of Novel belt material with the outer ripple plastic winding structure wall pipe of hollow reinforced rib, to overcome the defect on said structure.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, provides a kind of entwining tube pressure piping.Make composite strip with superhigh molecular weight polyethylene material, outside body, have the HDPE-PP composite winding reinforced pipe of entwining tube.The present utility model is achieved through the following technical solutions:
A kind of HDPE-PP composite winding reinforced pipe, by the tubing of the composite strip spiral winding welding with stiffening rib, it is characterized in that: the stiffening rib on described composite strip is PP bellows, PE material and PP bellows are mixed and made into semi-finished product by extruder by composite strip, there is symmetrical fusion molding junction plane composite strip both sides, first extrude PE by an extruder to expect on Stetch Wrapping Machine, be coiled into pipe liner, extrude PE by another extruder again and expect that sticking heat on internal lining pipe with PP ripple composite pipe is entwined, Stetch Wrapping Machine is wound around composite strip in a spiral manner and fuses into tubing body at junction plane overlap joint melten gel, tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding hollow boss stiffening rib thereon, hollow reinforced rib is perpendicular to tube wall, hollow boss stiffening rib is played a supporting role, improve the ring stiffness of whole pipeline, the crushing resistance of pipeline is also improved accordingly, described HDPE-PP composite winding reinforced pipe high density polyethylene is raw material, does supplemental support, Stetch Wrapping Machine is wound the plastic drain-pipe that internal surface is smooth, appearance has ripple struction with PP corrugated lining pipe.
The present utility model has good ring stiffness and face of weld heat seal strength high.
