Abstract
The utility model relates to an external antirot laminated oil pipe and steel pipe that is characterized in that: a PE antirot protection layer is tightly attached on the outer wall of oil pipe; the antirot protection layer is made from PE polyethylene material. The utility model additionally arranges an antirot layer on the external part of the oil pipe and steel pipe so as to exert the complete antirot function, which has the functions of resisting corrosion and wax, reducing the friction of fluids, increasing the service life of the oil pipe and steel pipe and reducing the exploitation cost and the well repair cost.
Description
Technical field
The utility model relates to composite oil pipe, is specifically related to a kind of internal and external anti-corrosive oil pipe that use in fields such as oil field, chemical industry, water delivery that is applied to, and belongs to International Classification of Patents F16L9/00 " combination rigid pipe " technical field.
Background technique
At present, Oilfield using all are the interior anticorrosion of glass fibre reinforced plastics and other material, do not adopt uses that be connected as a single entity of external anticorrosive material and oil pipe, steel pipe, cause the working life of oil pipe, steel pipe short, the cost increase of oil recovery, the life cycle shortening of water injection well.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of anticorrosion antiwear composite oil pipe, steel pipe with outer corrosion protection design is provided.
The purpose of this utility model is achieved through the following technical solutions.
The outer anticorrosion composite oil pipe steel pipe of PE is characterized in that closely being attached with the PE corrosion protective covering on the outer wall of oil pipe.
Described corrosion protective covering is to adopt the PE polythene material to make.
Anticorrosion antiwear composite oil pipe of the present utility model, steel pipe, in the outer installment of main body oil pipe, steel pipe anticorrosive coat, played antisepsis completely.Have anticorrosion, wax control, reduce the function of fluid friction.Improved working life of oil pipe, steel pipe.Also reduce cost of winning simultaneously, and reduced the expense of well workover.
Description of drawings
Accompanying drawing is the sectional structure schematic representation of the utility model anticorrosion antiwear composite oil pipe.
Among the figure: 1, oil pipe or steel pipe, 2, PE polyethylene asepticised outer layer.
Embodiment
With reference to accompanying drawing, anticorrosion antiwear composite oil pipe, steel pipe, its main body is the oil pipe 1 of steel, is surrounded by PE polyethylene asepticised outer layer 2 in the outside of oil pipe 1.
When installing asepticised outer layer 2, be to adopt a sleeving plastic extrusion equipment with PE polyethylene asepticised outer layer fusing back once-through, be coated on the steel pipe oil pipe 1.
The utility model can be widely used in the conveying of oil well, water injection well oil gas, coats the PE polythene material in the outside of oil pipe, makes oil pipe not have exposed part except that screw thread.Thereby played the internal and external anti-corrosive effect, improved the working life of oil pipe.
Claims (2)
1. the outer anticorrosion composite oil pipe steel pipe of PE is characterized in that: closely be attached with the PE corrosion protective covering on the outer wall of its oil pipe or steel pipe.
2. the outer anticorrosion composite oil pipe steel pipe of PE according to claim 1 is characterized in that: described outer corrosion protective covering adopts the PE polythene material to make.
