Abstract
The utility model belongs to the technical field of defeated oil pipe line, a nitrogen gas delivery hose for air drilling is disclosed. It constitutes should compound delivery hose technical scheme: comprise inner core pipe layer, enhancement layer and external coating, wherein the enhancement layer includes that a plurality of fibre winding layers constitutes in the weaving layer in the fibre winding layer outside with setting up in the heat preservation between fibre winding layer and setting up, external coating comprises with the spiral steel wire who inlays in its surface the rubber tube. This nitrogen gas delivery hose for air drilling good bending property not only has and also can satisfy be used for carrying nitrogen gas or have corrosive medium high temperature resistant, anti in external pressure, fire prevention, anticorrosive and wear resistance's requirement.
Description
Technical field
The utility model belongs to hose line technical field, relates to a kind of air drilling nitrogen delivery hose concretely.
Background technique
Air drilling nitrogen delivery hose is mainly used in the air drilling industry of oil field, for the connection between nitrogen-making device, atomising device, air compressor, condenser, pressure-increasing machine, chemical pump and chemical agent tank, connection and control manifold, standpipe.Comprise the circulatory mediators such as nitrogen, air and the gas-liquid mixture containing water and other corrosive materials especially for conveying, this kind of flexible pipe must have high temperature resistant, corrosion protection, high abrasion, anti-external and internal pressure, performance that flow resistance is little.But current used but its flexible pipe is formed by for sebific duct layer, enhancement layer and outer sebific duct layer in supplying nitrogen or other media, is therefore in use difficult to meet constant temperature, fire prevention, anticorrosion, wear-resisting requirement.
Model utility content
The purpose of this utility model is just to provide a kind of air drilling nitrogen delivery hose with high temperature resistant, anti-external and internal pressure, fire prevention, anticorrosion and wear-resisting property.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of air drilling nitrogen delivery hose, be made up of inner core tube layer, enhancement layer and external protection, it is characterized in that: the thermal insulation layer that described enhancement layer comprises some fiber winding layers and is arranged at Filament-wound Machine interlayer and the braid formation be arranged at outside fiber winding layer; Described external protection is made up of sebific duct and the spiral wire be embedded in its surface.
Form in the structure of above-mentioned air drilling nitrogen delivery hose,
---in described inner core tube layer, be provided with the polyester fiber yarn of having wrapped up glue-line be wound transition layer;
---described fiber winding layer is made up of some steel wire winding layers and some steel strip winding layers, and described thermal insulation layer is arranged at steel wire winding layer and steel strip winding interlayer;
---described steel wire winding interlayer or and steel strip winding interlayer be provided with bonding layer;
---adjacent described steel wire winding interlayer is reverse-winding, and adjacent described steel strip winding interlayer is reverse-winding;
---described steel plate winding layer is overlap joint winding;
---on the inwall of described inner core tube layer, be provided with corrosion resistant plate spiral wound.
Air drilling nitrogen delivery hose provided by the utility model compared with prior art, have the following advantages: one, because the enhancement layer fiber winding layer and the thermal insulation layer be arranged at therebetween that form this delivery hose are formed, therefore greatly can improve medium constant-temperature performance in its pipe, be conducive to the constant temperature conveying of its medium; Its two, because the external protection forming this flexible pipe is made up of sebific duct and the spiral wire be embedded in its surface; Therefore not only greatly can improve the Global Macros to flexible pipe, and be conducive to the bending properties of body; They are three years old, due to form delivery hose steel wire winding interlayer or and steel strip winding interlayer be provided with bonding layer, therefore can greatly improve the steel wire winding interlayer that forms enhancement layer or and the integrality of steel strip winding interlayer, and under effectively avoiding delivery hose bent state, there is the generation of fracture or dog leg phenomenon.
Accompanying drawing explanation
The structural representation of the air drilling nitrogen delivery hose that Fig. 1 provides for the utility model.
Embodiment
Be described in further details below in conjunction with the structure of accompanying drawing to the air drilling nitrogen delivery hose that the utility model provides.
Be illustrated in figure 1 the structural representation of the air drilling nitrogen delivery hose that the utility model provides.This delivery hose is by comprising for the Inner core tube layer 1 of supplying nitrogen, enhancement layer 2 and being compound in sebific duct 3 that the outer glue-line outside it formed and the spiral wire 6 be embedded in its surface is formed.Wherein enhancement layer comprise be wound around to contrary two-layer steel wire winding layer 21,22 and be wound around to contrary two-layer steel strip winding layer 23,24, above-mentioned steel wire winding layer and steel strip winding interlayer are provided with the sheet rubber that the length be made up through certain technique of materials such as rubber, aluminium hydroxide and carbon blacks and width mate with the girth of pipeline, line length respectively and form thermal insulation layer 25, be respectively arranged with the bonding layer 26 with lubrication and adhesive effect at two-layer steel wire winding interlayer and two-layer steel strip winding interlayer.The pipeline of this structure has one fixed width steel plate winding layer owing to employing, and the winding direction of two-layered steel plates winding layer is contrary, therefore substantially increase the overall performance of delivery hose, effectively overcome the generation of dog leg that independent steel wire winding layer very easily occurs and breakage phenomenon.
In the structure forming above-mentioned air drilling nitrogen delivery hose,
---in order to improve lubrication and the bond properties of steel wire winding layer and inner core tube interlayer further, and preventing wrap wire from entering in the tube wall of inner core tube, having the polyester fiber yarn of having wrapped up glue-line to be wound transition layer 4 in its arranged outside;
---when being wound around in overlap joint 5 when between the steel plate of formation steel plate winding layer, because the sliding effect between overlap joint is better, so make the integrally bending performance of delivery hose better, be convenient to its flexibility and use;
---in order to improve the wear-resisting of flexible pipe and corrosion resistant performance further, the inwall of inner core tube layer 1 forming delivery hose is provided with corrosion resistant plate spiral wound 7.
In the structure forming above-mentioned delivery hose enhancement layer, the number of plies of steel wire winding layer and steel strip winding layer is determined according to the size of delivery hose diameter; General be respectively arranged on 2-3 layers comparatively suitable, namely not only can meet the needs of pressure, and the ductility of pipeline also can be met the demands, so that lay.
This delivery hose is not only applicable to the conveying of air drilling nitrogen, but also can satisfy the demand and have the conveying of the media such as constant temperature, fire prevention, anticorrosion, wear-resisting requirement air and the gas-liquid mixture containing water and other corrosive materials.
