Abstract
The utility model relates to a yellow jacket pipe for reutilizing waste oil pipe which solves the problem that the existing anticorrosion oil pipes have poor anticorrosion properties, environment pollution, high cost, short service life and large amount of idling waste oil pipes. The yellow jacket pipe for reutilizing waste oil pipe is characterized in that: two ends of a waste oil pipe (2) is sheathed with polyethylene protecting pipes (4) after welding with joints (1, 5) via friction, and polyamine esters (3) are filled between the pipes (2, 4). Large numbers of idling waste oil pipes can be kept on using after treatment, waste is changed into valuable thing, investment is reduced, the production cost of oil field ground engineering is decreased, and the economic benefit of an oil production factory is raised.
Description
Technical field:
The utility model relates to the used a kind of yellow jacket tube of oilfield surface construction construction, belongs to the yellow jacket tube that old oil pipe utilizes again.
Background technique:
The tens thousand of kilometers of various pipelines that oilfield surface construction construction is used, most anti-corrosion pipe adopt asphalt anti-corrosion pipe, three layers of PE anti-corrosion pipe, epoxy resin coating antiseptic pipe; The asphalt anti-corrosion pipe, when hot weather construction, be subjected to the easy deformation that influences of high temperature, even trickling, easy embrittlement during low temperature makes the anticorrosive coat fragmentation, thereby reduces and lose antiseptic property to pipe, moreover the medium temperature that this pipe is carried is low, the using scope of anticorrosive coat is restricted, and is seriously polluted, and difficult quality reaches design standard and requirement; Three layers of PE anti-corrosion pipe production technology and structure are all very complicated, the cost of production height; There is the water absorption rate height in epoxy resin coating antiseptic pipe, and anti-mechanical shock, anti-machinery scratch poor performance, and construction and carrying anticorrosive coat are fragile, have a strong impact on antiseptic effect; Like this, just make that the corrosion at pipe joint place is even more serious, cause the leakage of liquid in the pipeline, make oil pipe scrap the working life of having reduced oil pipe, caused a large amount of idle of old oil pipe.
The model utility content:
Existing antisepsis oil pipe antiseptic property is poor in order to overcome, befouling environment, cost height, working life short, the big deficiency of the idle amount of old oil pipe, the yellow jacket tube that the utility model provides a kind of old oil pipe to utilize again, the yellow jacket tube that this old oil pipe utilizes again has that antiseptic property is good, cost is low, long service life, pollution-free, idle old oil pipe is effectively utilized, turn waste into wealth, can save a large amount of funds for enterprise.
The technical solution of the utility model is: the yellow jacket tube that this old oil pipe utilizes again comprises old oil pipe, is nested by the polyethylene protecting tube after the friction of old oil pipe two ends is welded with joint, is filled with polyamine fat between old oil pipe and polyethylene protecting tube.
The material of above-mentioned old oil pipe is a medium carbon alloy steel, and the material of joint is a low carbon steel.
The beneficial effect that the utlity model has is: because the yellow jacket tube that utilizes again of this old oil pipe has adopted polyamine fat and the polyethylene protecting tube anti-corrosion material as old oil pipe, antiseptic property is good, the intensity height, and shock-resistant and mechanical scuffing, production technology is simple; Old oil pipe and joint adopt friction welding, and welding effect is good; Make idle old oil pipe obtain reasonable use, be that enterprise has saved a large amount of funds the working life that has prolonged oil pipe.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-joint among the figure, the old oil pipe of 2-, 3-polyamine fat, 4-polyethylene protecting tube, 5-joint.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, the yellow jacket tube that this old oil pipe utilizes again comprises old oil pipe 2, and the friction of old oil pipe 2 two ends is welded with joint (1,5) back and is nested by polyethylene protecting tube 4, is filled with polyamine fat 3 between pipe (2,4).In actual use, at first, low carbon steel joint (1, the 5) employing at the old oil pipe of medium carbon alloy steel 2 two ends is beaten the method for groove butt joint friction welding and weld, this welding method welding effect is good, the intensity height; Then, outside old oil pipe 2, put polyethylene protecting tube 4, polyamine fat 3 is to be full of between old oil pipe 2 and the polyethylene protecting tube 4 with the form that foams, like this, polyamine fat 3 just sticks on the inwall of the outer wall of old oil pipe 2, joint (1,5) and polyethylene protecting tube 4 securely and solidifies, and makes old oil pipe 2, joint (1,5), polyamine fat 3, polyethylene protecting tube 4 becomes one, antiseptic property strengthens greatly; Connection between the tube and tube has also just become the connection between the low carbon steel joint (1,5), and weldability is enhanced, and then, at the scene preservative treatment is done with polyamine fat 3 and polyethylene protecting tube 4 in the joint between the tube and tube.Obtained prolongation the working life of oil pipe.
This shows that the reparation of old oil pipe makes the idle in a large number old oil pipe in oil field be reasonably used, and has reduced the construction cost of oilfield surface engineering, has improved the economic benefit of oil recovery factory.
Claims (3)
