Abstract
The utility model discloses a corrosion resisting high-pressure hose which comprises an inner hose layer (1), a steel wire reinforcement layer (3), a middle rubber layer (4) and an outer rubber layer (6). The corrosion resisting high-pressure hose is characterized in that the inner hose layer is a hydrogenation nitrile rubber inner hose layer which is externally coated with an aramid fiber cloth layer (2), wherein the aramid fiber cloth layer (2) is externally wound with the steel wire reinforcement layer. The steel wire reinforcement layer is externally coated with a middle rubber gluing layer which is externally wound with a second layer of the steel wire reinforcement layer (5). The second layer of the steel wire reinforcement layer is externally coated with the outer rubber layer as a protecting layer. The corrosion resisting high-pressure hose is good in stability and corrosion resistance. Resisting impact force of the hose is improved, strength and flexibility of the hose are increased, and service life of the hose is effectively increased by over 50%.
Description
Technical field
The utility model relates to a kind of liquid or gas transmission pipeline, especially a kind of corrosion-resistant high pressure hose and production method thereof.
Background technique
The at present conveyings such as China's chemical industry, oil, gas mostly are the hard pipelines such as steel pipeline or glass fibre reinforced plastics with pipeline, not only weight is large, and cost is high, and connect inconvenience, poor stability.For overcoming defects; people begin research and development and carry out liquid or the conveying of gas thing with the alternative stereoplasm tube of flexible pipe; a kind of polyurethane enhancing flexible pipe and manufacture method thereof are disclosed such as Chinese patent 03121929.2; it is characterized in that inner core is the polyurethane flexible pipe of thin-walled; middle enhancement layer is braided steel wire; skin is the polyurethane flexible pipe, and its production method comprises the braided steel wire technique of the expressing technique of inner core, middle enhancement layer and the polyurethane-coated technique of external protection.Chinese patent 200420117147.0 disclosed a kind of High Pressure Hose Using for Marine Petroleum Geophysical Exploration and for example, it comprises that the nylon tube outer wall is coated with high tenacity polyester fiber braid and protective layer.Stereoplasm tube weight is large, price is high, inconvenient problem is installed although above-mentioned two kinds of flexible pipes have overcome, and their inner tube anti-corrosion capacitys are poor, especially to H
2The S erosion resistance a little less than, skin wears no resistance, and especially a little less than the impact resistance, seriously restricts flexible pipe using scope and working life.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of anti-corrosion capacity strong, the corrosion-resistant flexible pipe of wear-resisting and strong shock resistance, the purpose of this utility model realizes by following technical proposals: the utility model comprises the inner tube layer, the steel wire reinforcement layer, mesoglea and outer glue-line, it is characterized in that the inner tube layer is hydrogenation butyronitrile rubber inner tube layer, hydrogenation butyronitrile rubber inner tube layer is coated with the aramid fiber layer of cloth outward, the aramid fiber layer of cloth is wound with the steel wire reinforcement layer outward, the steel wire reinforcement layer is coated with middle glue bond layer outward, middle glue bond layer is wound with second layer steel wire reinforcement layer outward, and it is protective coating that second layer steel wire reinforcement layer is coated with outer glue-line outward.
Also be coated with the aramid fibre layer of cloth in the glue protective coating outside in case of necessity.
The utility model compared with prior art has following advantage: corrosion resistance is strong, the corrosion that hydrogenation butyronitrile rubber inner tube layer of the present invention more can be resisted acid, alkali and corrosive gas, the utility model inner glue layer and aramid fiber layer of cloth, aramid fiber layer of cloth and steel wire reinforcing layer, middle glue bond layer and steel wire reinforcing layer and outer glue protective coating are bonding closely, good stability is wear-resisting especially.The aramid fiber layer of cloth of the utility model outside inner glue layer improved the anti-impact force of flexible pipe greatly, increases intensity and the ductility of flexible pipe.Effective Raise working life of flexible pipe more than 50%.From above-mentioned situation as can be known the purpose of this utility model can realize.

Embodiment
Embodiment 1, as shown in Figure 1, the utility model comprises inner tube layer 1, steel wire reinforcement layer 3, mesoglea 4 and outer glue-line 6, it is characterized in that the inner tube layer is hydrogenation butyronitrile rubber inner tube layer, hydrogenation butyronitrile rubber inner tube layer is coated with aramid fiber layer of cloth 2 outward, and the aramid fiber layer of cloth is wound with the steel wire reinforcement layer outward, and the steel wire reinforcement layer is coated with middle glue bond layer outward, middle glue bond layer is wound with second layer steel wire reinforcement layer 5 outward, and second layer steel wire reinforcement layer is coated with outer glue protective coating outward.Consider further enhancing flexible pipe impact resistance, improve hose strength and ductility, present embodiment also is coated with the aramid fibre layer of cloth in the glue protective coating outside, i.e. at twice coating of outer glue protective coating makes the aramid fiber layer of cloth in wherein.
Claims (2)
1. corrosion-resistant high pressure hose, comprise inner tube layer (1), steel wire reinforcement layer (3), mesoglea (4) and outer glue-line (6), it is characterized in that: the inner tube layer is hydrogenation butyronitrile rubber inner tube layer, hydrogenation butyronitrile rubber inner tube layer is coated with aramid fiber layer of cloth (2) outward, the aramid fiber layer of cloth is wound with the steel wire reinforcement layer outward, the steel wire reinforcement layer is coated with middle glue bond layer outward, and middle glue bond layer is wound with second layer steel wire reinforcement layer (5) outward, and it is protective coating that second layer steel wire reinforcement layer is coated with outer glue-line outward.
2. corrosion-resistant high pressure hose according to claim 1 is characterized in that: also be coated with the aramid fibre layer of cloth in the outer glue protective coating.
