Abstract
The utility model belongs to a compound pipeline which is compounded by the steel and the polyurethane, which mainly solves the problems that the existing pipeline has poor self cleaning performance, large running resistance and the fouling are easily deposited in the inner wall. The utility model is characterized in that the surfaces of the inner walls of the compound pipeline and the steel (iron) pipeline are provided with a layer of the polyurethane elastomer (TPU) of the PEO slow-release polymer drag reducer. The utility model has the characteristics of good self cleaning performance, small running resistance, effective preventive performance of the fouling which is deposited on the inner wall of the pipeline, resistive acid, alkali, oil, corrosion of the sea water and attrition, good integrated performance of use and easy manufacture.
Description
The utility model relates to a kind of multiple tube, and particularly a kind of steel---polyurethane composite pipe road is used for slurry, powder body and various sealed type material-transporting system.
At present, in slurry, powder body and various sealed type material-transporting system, mostly adopt antiwear cast iron alloy pipe, wear-resistant alloy cast steel pipe and steel and rubber compound tube road.Its deficiency is: the self-cleaning property in antiwear cast iron alloy pipe, wear-resistant alloy cast steel pipe and steel and rubber compound tube road is poor, and fortune property resistance is big, in use the easy incrustation of its inwall.In addition, the manufacturing process complexity of above-mentioned pipeline, wear-resisting property and acidproof, alkaline-resisting, oil resistant, seawater corrosion resistance combination property are also good inadequately.
The purpose of this utility model be exactly provide at above-mentioned deficiency that a kind of self-cleaning is good, running resistance is little, can effectively prevent inner-walls of duct incrustation, steel---the polyurethane composite pipe road of manufacturing process tube list.
Technical solution of the present utility model is: a kind of multiple tube, comprise steel (iron) pipeline, and it is characterized in that: on the inner wall surface of steel (iron) pipeline, be provided with the polyurethane elastomer (TPU) that one deck contains PEO release polymer friction-reducing additive.
The thickness of the polyurethane elastomer described in the utility model technical solution (TPU) is 3～5mm.
The utility model is owing to adopt elastic polyurethane (TPU) body and steel (iron) pipeline that contain PEO release polymer friction-reducing additive to constitute multiple tube, thereby, both can guarantee that polyurethane elastomer (TPU) with the inner-walls of duct combination closely, have the characteristics that self-cleaning property is good, running resistance is little again, and polyurethane elastomer (TPU) itself has good toughness and intensity.Compare with antiwear cast iron alloy pipe, wear-resistant alloy cast steel pipe, steel and rubber compound tube road, have the following advantages:
1, has higher wear-resisting property;
2, self-cleaning is good, can prevent inner-walls of duct incrustation effectively in the using process;
3, PEO makes that running resistance significantly reduces in the material conveying process;
4, have excellent acid, alkaline-resisting, oil resistant, seawater corrosion resistance, wear-resisting comprehensive usability;
5, manufacturing process is simple, and is convenient for installation and maintenance, and cost is low, saves the steel use amount greatly.
Accompanying drawing is a schematic cross-section of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in drawings, common steel tube 1 is through after cleaning roughening treatment, spray the polyurethane elastomer (TPU) 2 that one deck evenly adheres within it on the wall surface, according to the concrete applied environment of pipeline, add an amount of PEO release polymer friction-reducing additive again.The optimum thickness of polyurethane elastomer (TPU) 2 is 3～5 millimeters.
Claims (2)
1, a kind of multiple tube comprises steel (iron) pipeline (1), it is characterized in that: be provided with the polyurethane elastomer (TPU) (2) that one deck contains PEO release polymer friction-reducing additive on the inner wall surface of steel (iron) pipeline (1).
2, a kind of multiple tube according to claim 1 is characterized in that: the thickness of described polyurethane elastomer (TPU) (2) is 3～5mm.
