Abstract
The utility model provides a composite pipeline of ultra-high molecular weight polyethylene and glass fibre reinforced plastics. The utility model is suitable for being a pipeline with an erosion angle less than 30 DEG for hydraulic transport sands, ashes, and other solid particulates. The outer shell of the utility model is glass fibre reinforced plastic. An inner liner and the inner wall of the outer shell are compounded into an integral ultra-high molecular weight polyethylene. The molecular weight is greater than three million. The outer shell has light weight and high strength, and the inner liner has excellent wear resistance, self lubricity, and scale resistance. The pipeline after compounded has light weight, low construction cost, and low installation and maintenance cost. The composite pipeline of ultra-high molecular weight polyethylene and glass fibre reinforced plastics is particularly suitable for being a pipeline of a linear conveyor segment.
Description
The utility model relates to a kind of ultra-high molecular weight polyethylene, glass fibre reinforced plastic composite pipe of carrying solid particles such as ore in sand form, lime-ash with waterpower.
The waterpower output of distance is grown by thermal power plant with pipeline to the lime-ash of afterburnt coal now, must solve the unimpeded problem of the caused pipeline of lime-ash fouling that is subjected to caused pipe wear problem of lime-ash erosion and high calcium coal ash, though the wear-resistant alloy cast steel pipeline can solve wear problem substantially, its cost height, deal weigh; Its lime-ash scale problems is with adding hydrochloric acid, antisludging agent or make methods such as lime-ash hydromagneticization, but the expense height, effect is still undesirable.
The purpose of this utility model is to provide that a kind of wear resistance is good, resistive connection is dirty, ultra-high molecular weight polyethylene, the glass fibre reinforced plastic composite pipe of less expensive again.
Task of the present utility model is achieved in that pipeline has shell and liner, and shell is a glass fibre reinforced plastics, and liner is the ultra-high molecular weight polyethylene that is compounded on the outer casing inner wall.
The shell of above-mentioned multiple tube is the composite material of synthetic resin and glass fibre or glass cloth, to bear pipeline pressure; Lined with ultra-high molecular weight polyethylene (english abbreviation is UHMW-PE), its molecular weight is greater than 3,000,000, have excellent abrasion resistance and self lubricity, because of nonpolarity, chemical stability is good, surface tension is little, therefore anti-fouling tendency might as well, the pipeline after compound is in light weight, engineering cost is low, the installation and maintenance expense is low, be suitable for and make waterpower ash discharge slag, the erosion angle is less than 30 ° pipeline.
Below with accompanying drawing in conjunction with the embodiments, concrete structure of the present utility model is further described again:
The ultra-high molecular weight polyethylene that Fig. 1 provides for the utility model, the plan view of glass fibre reinforced plastic composite pipe.
Fig. 2 is the right elevation of Fig. 1 structure.
As shown in the figure, conduit enclosure 1 is to be stock with synthetic resin, and compound with reinforcing materials such as glass fibre or glass cloth is the glass fibre reinforced plastics of high-strength light, and wherein synthetic resin can be unsaturated polyester resin, epoxy resin or vinyl ester resins etc.Pipe lining 2 usefulness molecular weight are compounded on the inwall of glass fibre reinforced plastics casing greater than 3,000,000 ultra-high molecular weight polyethylene, form multiple tube.Its inner lining material is at good mechanical property below 80 ℃, double anti-lime-ash fouling, especially the erosion angle less than 30 ° operating mode under, wear-resisting, the selflubricating of material self and low coefficient of friction performance, embodied good wear-resistant characteristics, be suitable for and make the pipeline that waterpower is carried solid particle straightways such as ore in sand form, lime-ash.
