Abstract
The utility model belongs to the technical field of high-pressure rubber pipes and discloses an armour pipe line which is used for oil exploration and has resistance to high pressure. According to the technical scheme, the armour pipe line is composed of an inner rubber pipe, wherein the inner rubber pipe is used for transporting high-pressure medium, a framework layer and an outer rubber pipe layer are arranged outside the inner rubber pipe, and the framework layer is formed at least one layer of winding or weaving steel wire layer and a middle glue bonding layer which is coated on the inner wall of the steel wire layer, and an outer glue bonding layer and a steel belt winding layer are arranged between the outermost winding or the weaving steel wire layer which is capable of forming the framework layer and the outer rubber pipe layer in sequence. The armour pipe line is not only capable of effectively preventing pointed objects from penetrating but also improving safe and reliable performance of the operation of the armour pipe line. Meanwhile, the armour pipe line is further capable of effectively overcoming immersion of humidity along the winding steel wire gaps and enables pipe lines to be good in pressure-bearing performance, and the service life is prolonged.
Description
Technical field
The utility model belongs to the high-pressure rubber pipe technical field, relates to a kind of requirement that is used in the oil exploration concretely and has high voltage bearing armor pipeline.
Background technique
Along with the development of oil exploration industry, the drilling well of petroleum gas is more and more darker, and is more and more higher to the flexible manifold performance requirement of ultrahigh pressure.At present widely used various as prevent that middle pressure-bearing framework layer that defeated material sebific duct, drilling mud Circulation pipe and the ultrahigh pressure oil pipeline of blowout, its structure include the interior pipe layer of carrying high-pressure medium, the steel wire that several layers is arranged that is wrapped in its outside twines braid and middle glue bond layer constitutes and the protective layer that is made of outer glue-line from constituting.The high pressure resistant sebific duct of this structure is because structural defective, make and in use have following defective: one, although outer glue-line has wear-resisting performance, but because Environmental Conditions is abominable, its spreadable life thresold is short, the very fast meeting of the steel wire casing ply corrosion and damage that its inner institute twines or weaves after outer glue-line wearing and tearing causes the load performance of body to descend and explosion; Its two twine or braiding forms because middle the pressure-bearing framework layer that constituted is a steel wire, its sharp shaped material is easy to thrust wherein by the slit between steel wire, causes the pipeline damage; Its three: the winding steel wire layer of line end flange connections is exposed to the outside, and seawater moisture very easily enters by the steel wire floor that twines, and causes its damage that is corroded, and shortens its working life greatly.
The model utility content
The purpose of this utility model just provides that a kind of load performance is higher, Security is better and the armor pipeline of long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of armor pipeline comprises the interior sebific duct that is used to carry high-pressure medium, and the outer installment of sebific duct has winding or the braided steel wire layer and the framework layer and the outer sebific duct layer that are coated on the middle glue bond layer formation on the described steel wire floor inwall of one deck at least in this; It is characterized in that: the outermost that constitutes described framework layer twine or the braided steel wire layer and described outside the sebific duct interlayer be disposed with outside glue bond layer and steel band winding layer.
The additional technical feature that constitutes above-mentioned armor pipeline comprises:
---constitute winding of described one deck at least or the nexine steel wire floor in the braided steel wire layer and be set to the steel band winding layer;
---the width of described steel band winding layer is 1-5 centimetres, and the angle of the winding of its winding angle and described steel wire floor or braiding is consistent;
---described steel band winding layer twines simultaneously side by side at least two described steel bands;
---in described sebific duct and constitute described winding or the nexine steel wire floor of braided steel wire layer between be provided be wound in 1 to 5 layer woven dacron on the sebific duct.
Armor pipeline provided by the utility model compared with prior art, owing to be provided with steel band winding layer in the structure of this armor pipeline with certain width, therefore, not only can effectively avoid thrusting of sharp shaped material, the safety and reliability of its operation have been improved, the winding layer of steel band can improve the degree of compaction of the framework layer that is wrapped up greatly simultaneously, improved its sealability, effectively overcome the immersion of moisture along the steel wire slit of twining, make that the load performance of pipeline is better, further improved its working life.
Description of drawings
The structural representation of the armor pipeline that Fig. 1 provides for the utility model.
Embodiment
The structure of the armor pipeline that the utility model is provided below in conjunction with accompanying drawing is described in further details.
Be illustrated in figure 1 as the structural representation of the armor pipeline that the utility model provides.The structure that constitutes this armor pipeline is by the interior sebific duct 1 that is used for slurry conveyed, oil or other high-pressure mediums, the outer installment of sebific duct has by four layers and twines or framework layer that the middle glue bond layer 3 of braided steel wire layer 2 and four layers forms in this, glue bond layer 4 outside outside outermost winding that constitutes above-mentioned framework layer or braided steel wire layer 21, being disposed with, steel band winding layer 5 and outside sebific duct layer 6.
In the structure of above-mentioned armor pipeline,
---in order further to improve the resistance to compression and the paracentesis resistance energy of pipeline, the multi-lay winding of formation or the nexine steel wire floor 22 in the braided steel wire layer 2 can be arranged to the steel band winding layer;
---the winding angle that constitutes above-mentioned steel band winding layer is generally with the angle unanimity of the winding or the braiding of steel wire floor 2, and the width of steel band winding layer is arranged between 1-5 centimetres, and at least two steel bands 51 twine simultaneously side by side;
---in order further to improve the bending properties of armor pipeline, 1 to 5 layer woven dacron 7 in interior sebific duct 1 and 22 settings of nexine steel wire floor are wound on the sebific duct 1.
In the structure of above-mentioned armor pipeline, the number of plies that constitutes glue bond layer in the winding of framework layer or the braided steel wire layer is set as required, and after being provided with the steel band winding layer, because the load performance of pipeline improves greatly, so its number of plies can suitably reduce.
