Abstract
The utility model discloses a corrosion resistant oil pipe connector, which is adaptable to water wells or severely corroded oil wells. The corrosion resistant oil pipe is composed of an oil pipe connecting hoop (1) and an oil pipe body (3), a ring-shaped groove between threads of two ends of the oil pipe connecting hoop (1) is internally equipped with a corrosion resistant sealing ring (2), when the oil pipe connecting hoop (1) is connected with the oil pipe body (3), outer threads of the oil pipe body (3) are screwed on the sealing ring (2), and a corrosion resistant layer (4) in the oil pipe body (3) and the sealing rings (2) in the oil pipe connecting hoop (1) form a constant sealing corrosion resistant layer, thereby resolving the corrosion problem in the ring-shaped groove between threads of two ends of the oil pipe connecting hoop (1), prolonging the service life of the oil pipe, and reducing underground accidents.
Description
Technical field
The utility model relates to a kind of antisepsis oil pipe joint, and it is applicable in the oil well of well and seriously corroded and uses.
Background technique
The present antisepsis oil pipe that uses, its body portion scribbles anticorrosive coat or is lined with anticorrosive coat, but box cupling two ends screw thread intermediate annular groove internal cause does not have anticorrosive coat, easily causes corrosion under the effect of aggressive medium and liquid turbulence, reduce the working life of oil pipe, caused down-hole accident when serious.
Summary of the invention
The purpose of this utility model provides a kind of antisepsis oil pipe joint, to improve the whole corrosion resistance of oil pipe.
The utility model is made up of tubing coupling, oil pipe body, set up etch-proof seal ring in its tubing coupling two ends screw thread intermediate annular groove, when tubing coupling is connected with the oil pipe body, the outside thread of oil pipe body screws on seal ring, anticorrosive coat in the oil pipe body and the seal ring in the tubing coupling form a kind of continuous seal layer of resist, thereby have solved the problem of circular groove internal corrosion between tubing coupling two screw threads.
The utility model is simple in structure, and is easy to use, and corrosion resistance is good, can prolong the working life of oil pipe, reduces the generation of down-hole accident.
Description of drawings:
Fig. 1 is the utility model structure principle chart
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model is made up of tubing coupling (1), oil pipe body (3), set up etch-proof seal ring (2) in the screw thread intermediate annular groove of its tubing coupling (1) two ends, when tubing coupling (1) and oil pipe body (3) when being connected, the outside thread of oil pipe body (3) screws on seal ring (2), anticorrosive coat (4) in the oil pipe body (3) and the interior a kind of continuous seal layer of resist of seal ring (2) formation of tubing coupling (1), thus the problem of circular groove internal corrosion between box cupling two screw threads solved.
Claims (1)
- A kind of antisepsis oil pipe joint, it is made up of tubing coupling (1), oil pipe body (3), it is characterized in that having set up etch-proof seal ring (2) in the screw thread intermediate annular groove of tubing coupling (1) two ends.
