Abstract
The utility model relates to a high pressure metal hose used for the heavy oil field well head steam piping system, which comprises a corrugated pipe and a wire screen sleeve of the corrugated pipe periphery. Both ends of the corrugated pipe are connected to a joint pipe or a kava joint. The waveform of the corrugated pipe is an intensive spiral wave, and the wire screen sleeve of the corrugated pipe periphery is a multi-layer screen sleeve structure. The high pressure hose for the heavy oil field well head steam pipes of the utility model has the capacity of the displacement compensation under 420 DEG C. high temperature and 16Mpa pressure, which can be used for the replacement spherical compensation device and the same types of products. The utility model can bear high pressure and high temperature with good flexibility, simple structure, excellent technology, safe and reliable compensation displacement, which is applicable to the steam piping systems. The utility model is applied in the heavy oil field well head steam piping system for displacement compensation to prevent the occurrence of leakage, which is also applicable to the high temperature high pressure pipelines in other industries for displacement compensation. In the utility model, the strengthening parts in the middle of the annular corrucated pipe are eliminated, and the corrugated pipe length of the utility model is not subject to the processing restrictions. The corrugated pipe is long and no additional connection pipe is required in the middle of the corrugated pipe. With simple structure and less welding seams of the corrugated pipe, the utility model is provided with excellent technology and large quantity of compensation.
Description
Technical field
The utility model relates to a kind of high-pressure metal flexible pipe that is used for oil-field thick-oil well head steam injection pipe-line system.
Background technique
At present, have in two method carry out bit shift compensation in oil-field thick-oil well head steam injection pipe-line system: the one, adopt spherical compensator, it has certain compensate for displacement effect, but along with wearing out of seal element, still can leak, and maintenance is frequent, working life is short.The 2nd, the metallic hose of employing circumferential wave, this metallic hose rigidity is big, and compliant section is short, and welded steel pipe is wanted in the centre, and weld seam is many, and operation is numerous, complex structure, compensation rate is little under the equal length.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of manufacturing procedure few, simple in structure, and compensation rate is big, leak free thick oil filling steam pipework high pressure hose.
Technical solution of the present utility model:
A kind of thick oil filling steam pipework high pressure hose, it includes bellows and peripheral wire sets thereof, the two ends of bellows all are connected with to be taken over or the slips joint, and the waveform that it is characterized in that bellows is intensive helicon, and its peripheral wire sets is the multilayer nets structure.
Thick oil filling steam pipework high pressure hose of the present utility model has and bears the ability of carrying out bit shift compensation under 420 ℃ of high temperature, the 16MPa pressure, alternative spherical compensator and product of the same type.The utility model pressure-bearing height, high temperature resistant, flexible good, simple in structure, good manufacturability, compensate for displacement is safe and reliable, is applicable to steam pipeline system.The utility model is used for oil-field thick-oil well head steam injection pipe-line system, carries out bit shift compensation and can prevent to leak generation, and the High Temperature High Pressure pipeline that also may be used on other industry advances bit shift compensation.The utility model has saved the reinforcement part in the middle of the ring bellows, and its bellows length is not subjected to the processing restriction, the ripple pipe range, and the centre need not increase adapter, and is simple in structure, and the bellows weld seam is few, good manufacturability, compensation rate is big.
Description of drawings
Fig. 1 is a cross-sectional configuration schematic representation of the present utility model.
Fig. 2 is a profile schematic representation of the present utility model.
Embodiment
As Fig. 1,2, thick oil filling steam pipework high pressure hose of the present utility model, it includes bellows 1 and peripheral wire sets 2 thereof, the two ends of bellows 1 all are connected with takes over 3 (or slips joints), characteristics of the present utility model are, the waveform of bellows 1 is intensive helicon, and its peripheral wire sets 2 is the multilayer nets structure, its number of plies is decided according to the high-pressure work pressure of pipeline medium, generally selects three to five layers for use.
When the utility model is made, loose helical bellows with routine carries out the processing of secondary pressure ripple earlier, make it into the bellows 1 of intensive helicon, take over 3 (or slips joints) in its two ends welding again, peripheral suit Composite Steel silk screen at them overlaps 2 at last, this multilayer wire sets 2 can adopt the distribution welded structure, and the two ends of multilayer wire sets 2 and each self-corresponding adapter 3 outer wall are welded as a whole get final product.
Because the utility model has adopted the bellows 1 of intensive helicon, so need the reinforcement part that in trough, be provided with when having saved traditional ripple pipe and being used for the high pressure operating mode, can save the middle adapter of traditional bellows simultaneously, so processing technology is simplified greatly for guaranteeing that active length need increase, cost reduces greatly, weld seam reduces, good manufacturability, simultaneously, bellows 1 of the present utility model flexible good, high temperature resistant, processing length is long, and compensation rate increases under equal length.The utility model can improve pressure-bearing, the withstand voltage properties of flexible pipe greatly owing to adopt multilayer wire sets 2.Jointing of the present utility model can weld adapter 3 or slips joint, and is various informative, easy installation and reliable.The utility model also can be provided with sheath 4 in the appearance of bellows 1 and multilayer wire sets 2 thereof, and Safety performance is improved.
Claims (3)
1, a sharp thick oil filling steam pipework high pressure hose, it includes bellows and peripheral wire sets thereof, the two ends of bellows all are connected with to be taken over or the slips joint, and the waveform that it is characterized in that bellows is intensive helicon, and its peripheral wire sets is the multilayer nets structure.
2, thick oil filling steam pipework high pressure hose according to claim 1 is characterized in that the number of plies of described multilayer wire sets is selected three to five layers for use.
3, thick oil filling steam pipework high pressure hose according to claim 1 is characterized in that being provided with sheath in the appearance of bellows and multilayer wire sets thereof.
