Abstract
The invention discloses a method for compounding the super high molecular weight polyethylene pipe with steel pipe, which is characterized in following steps: first selecting the super high molecular weight polyethylene pipe whose outer diameter is bigger 2-5% than the inner diameter of selected steel pipe; reducing the diameter of super high molecular weight polyethylene pipe via reducing machine to make its outer diameter litter less than the inner diameter of steel pipe; entering the super high molecular weight polyethylene pipe via diameter-fixed guide sheath into steel pipe by the drawing machine; since the super high molecular weight polyethylene pipe has memory function, it can compound the steel pipe closely. The inventive compounded pipe can replace present oil-pumping pipe made from steel and prolong the service life more than 4 times, while it can fully use old steel pipe with same effect of new steel pipe to reduce the resource and cost.
Description
Technical field
The present invention relates to the combination process of a kind of ultrahigh molecular weight polyethylene tubing and steel pipe.
Background technology
Plastic pipe and steel pipe be compounded with many methods, wherein adopt binder with faying face cohere for the method for one more commonly used.Ultra-high molecular weight polyethylene is a kind of material of mobile extreme difference, and the tubing with this kind material is made owing to its intrinsic characteristic, is difficult to find suitable binder that it and steel pipe are combined with each other effectively.
Studies show that at present, ultrahigh molecular weight polyethylene tubing is the high performance plastic pipe that a kind of wearability height, good corrosion resistance, impact resistance height, coefficient of friction are low, self-cleaning action is arranged, its wearability is 5～7 times of steel, be 3～4 times of common polythene tubing, thereby be suitable as very much oil well oil-pumping tubing in the oil field, with itself and steel pipe compound after, alternative existing steel oil pick-up tube, and can increasing the service life more than 4 times.
Summary of the invention
At the problems referred to above, it is a kind of with ultrahigh molecular weight polyethylene tubing and the compound technology of steel pipe that the present invention will provide.
The concrete technical scheme that the present invention adopts is: the combination process of described ultrahigh molecular weight polyethylene tubing and steel pipe mainly may further comprise the steps: at first select the ultrahigh molecular weight polyethylene tubing of its external diameter than the internal diameter big 2%～5% of selected steel pipe for use, make ultrahigh molecular weight polyethylene tubing pass through the size reducing machine undergauge then, make that the external diameter of ultrahigh molecular weight polyethylene tubing is more smaller than the internal diameter of steel pipe, under the effect of hauling machine, ultrahigh molecular weight polyethylene tubing enters into steel pipe by the sizing fairlead; After after a while, because of ultrahigh molecular weight polyethylene tubing has memory function, ultrahigh molecular weight polyethylene tubing will closely be combined with each other with steel pipe.
The molecular weight of ultra-high molecular weight polyethylene recited above is between 1,000,000～3,000,000.
And after through the size reducing machine undergauge, the external diameter of ultrahigh molecular weight polyethylene tubing is 95%～98% of a pipe diameter.
And, in actual fabrication, can select the internal diameter of sizing fairlead littler by 1%～2% than the internal diameter of steel pipe; With handled easily.
Advantage of the present invention is: the multiple tube that utilizes above-mentioned combination process to make substitutes the oil well oil-pumping tubing that existing clean steel is made, and can improve service life more than 4 times; And, can make full use of some old steel pipes carry out compound, and its result of use with compound with new steel pipe be consistent, so can economize on resources widely, reduce cost.
Embodiment
The invention will be further described below in conjunction with embodiment.
Do the external diameter of the ultrahigh molecular weight polyethylene tubing of molecular weight between 1,000,000-3,000,000 than the big 2%-5% of internal diameter of selected oil well steel pipe, then at normal temperatures by the size reducing machine undergauge, the reduced diameter of superhigh molecular weight polyethylene pipe is arrived the 95%-98% of pipe diameter, again under the guide effect of sizing fairlead, by hauling machine with superhigh molecular weight polyethylene pipe be incorporated into carry out in the steel pipe compound, utilize the memory function of superhigh molecular weight polyethylene pipe, begun to original size restoration behind ultrahigh molecular weight polyethylene tubing behind the undergauge process certain hour, and, make ultrahigh molecular weight polyethylene tubing and steel pipe closely be combined with each other because the internal diameter of steel pipe is limit.This kind complex method does not need binder.
In actual fabrication, four groups of reducing rollers can be set in size reducing machine, the forming diameter rate of change of every pair roller is at 0.5%-1%; And the linear velocity of every group of roller also is different, and the difference of each group is controlled at 0.5%-1.5%; And can be equipped with motor and reduction box respectively to them, if desired, can also carry out independent speed governing motor.
The sizing fairlead places the leading-in end of the internal lining pipe of steel pipe usually, and it mainly plays sizing, importing effect, to reduce ultrahigh molecular weight polyethylene tubing and the chance that steel pipe directly contacts in recombination process, has made things convenient for construction; And, do the internal diameter of sizing fairlead littler by 1%～2% usually than the internal diameter of steel pipe.
In actual fabrication, also can select the hauling machine of frequency control for use, and with the draught line speed of hauling machine be controlled at 2-15 rice/minute, hauling machine is connected with ultrahigh molecular weight polyethylene tubing with interface unit by pull rope, to realize traction function.
In addition, the reminiscence of ultrahigh molecular weight polyethylene tubing needs the time, therefore the multiple tube after compound is revised---as amputate the internal lining pipe that exceeds steel pipe etc. and must behind official hour, carry out, generally after 24 hours, preferably be controlled at after 48 hours and carry out.
By can be as can be known described, the multiple tube that utilizes above-mentioned combination process to make substitutes the oil well oil-pumping tubing that existing clean steel is made, and can improve service life more than 4 times; And, can make full use of some old steel pipes carry out compound, and its result of use with compound with new steel pipe be consistent, so can economize on resources widely, reduce cost.
