Abstract
The utility model aims to design a dredge pipeline suitable for dredging engineering, good in wearing resistance and impact resistance, high in loading capacity and excellent in self-lubrication, and relates to dredging pipelines, in particular to an ultra-high molecular weight polyethylene (UHMWPE) steel-plastic composite pipe for dredging. The technical scheme adopted by the utility model is that a steel pipe and a UHMWPE pipe are adopted. The UHMWPE steel-plastic composite pipe for dredging is characterized in that the steel pipe serves as the outer layer of the steel-plastic composite pipe, the UHMWPE pipe serves as the inner layer of the steel-plastic composite pipe, the UHMWPE pipe and the steel pipe are bonded into a whole by a polyethylene adhesive, flanges are connected to two ends of the steel pipe, grooves are formed near the inner rings of the end surfaces of the flanges, abrasion-resistant rubber pads are bonded between the ends of the UHMWPE pipe and the grooves of the flanges, and the abrasion-resistant rubber pads and the flanges form an integral composite flange. The UHMWPE steel-plastic composite pipe for dredging can be widely used as hydraulic transportation pipelines for dredging or hydraulic reclamation.
Description
Technical field
The utility model relates to the pipe technology field, especially dredging Wear Resisting Steel plastic composite.
Background technique
Because traditional steel dredging pipe is perishable, easy to wear when the sediment, working life is short, safeguard/to change the pipeline frequency high, the defectives such as purchase cost height.Therefore, develop a kind of novel wear resistant pipeline, decrease reduces the basket purchase cost of tubing because safeguarding/change the frequency that pipeline causes termination of pumping, improves engineering construction efficient and profit, is the active demand of dredging and reclamation industry.
Summary of the invention
To be that design is a kind of be applicable to that the dredging works wear resistance is good, shock-resistant, bearing capacity is high, the heavy caliber ultra-high molecule dimension of selflubricating good (on-way resistance is little) is moulded the composite dredge pipe road to the problem that the utility model need to solve.
The technical solution of the utility model adopts steel pipe and the superhigh molecular weight polyethylene pipe of molecular weight more than 9,200,000, it is characterized in that steel pipe is as the skin of steel-plastic composite pipe, described superhigh molecular weight polyethylene pipe is as the internal layer of steel-plastic composite pipe, be integral both are bonding with the agent of polyethylene gluing between superhigh molecular weight polyethylene pipe and the steel pipe, the steel pipe two ends are connected with flange, nearly inner ring at end face of flange is fluted, the pipe end of superhigh molecular weight polyethylene pipe bonding abrasion-proof rubber cushion to the flange groove, abrasion-proof rubber cushion and flange form compound integral (type) flange.
Outstanding feature of the present utility model is because the internal layer of steel-plastic composite pipe adopts the super high molecular weight material, has overcome the withstand voltage not wear-resisting shortcoming of conventional steel, has the serial characteristics such as excellent wear resistance, shock-resistant, corrosion-resistant, selflubricating, anti stick; Because the skin of steel-plastic composite pipe adopts steel pipe, overcome the wear-resisting not withstand voltage shortcoming of superhigh molecular weight polyethylene pipe, have that mechanical strength is high, the characteristics of good rigidly, good mechanical property is arranged, can bear the pressure of 2～3.0MPa, can be widely used in long apart from dredging, hydraulic reclamation, etc. the waterpower transportation art, be desirable dredging pipeline.
Description of drawings

Fig. 2 is anti-displacement ring enlarged diagram of the present utility model.
Embodiment
The utility model adopts wall thickness 10～15mm steel pipe 2 as the skin of steel-plastic composite pipe, adopts the superhigh molecular weight polyethylene pipe 3 of molecular weight more than 9,200,000 as the internal layer of steel-plastic composite pipe, and the wall thickness of superhigh molecular weight polyethylene pipe is 25～30mm; Be integral both are bonding with the agent of polyethylene gluing between the superhigh molecular weight polyethylene pipe of internal layer and the outer field steel pipe; The steel pipe two ends are connected with flange 1, and are fluted at the nearly inner ring of end face of flange, the pipe end of superhigh molecular weight polyethylene pipe bonding abrasion-proof rubber cushion 6 to the flange groove, and abrasion-proof rubber cushion and flange are bonded into compound integral (type) flange.Be embedded anti-displacement ring 5 at flange and steel-plastic composite pipe joint A, close end at steel-plastic composite pipe is connected the high-molecular polythene pipe with holding down bolt 4 with steel pipe inner wall, can effectively solve the displacement that steel pipe and super ultrahigh molecular weight polyethylene tubing expand with heat and contract with cold and cause.Steel-plastic composite pipe of the present utility model can be widely used in dredging or hydraulic reclamation waterpower conveyance conduit, is particularly useful for latus rectum 800mm～1200mm dredging pipeline.
