Abstract

The utility model discloses an oil pipe and sleeve thread protector capable of preventing deforming, chapping and sticking at temperature of -46-66 DEG C, preventing breaking under 5kg tension and preventing impact. The thread protector comprises a main body (1); the upper end of the main body (1) is closed while the lower end of the main body (1) is opened; thread (4) is formed on the inner wall of the main body (1); an annular boss is arranged on the edge of the main body (1) along the circumference; a group of corresponding notches (5) are formed on the annular boss; a steel wire net (1) is arranged in a post body of the main body (1); and steel rings (2) are respectively fixedly arranged on the upper end and the lower end of the steel wire net (1). The thread protector has the characteristics of preventing the deforming, the chapping and the sticking at the temperature of -46-66 DEG C and preventing the breaking under the 5kg tension.

Description

-46 ℃~66 ℃ indeformable not bonding 5kg pulling force that do not chap constantly take off shock resistance oil pipe, casing tube screw thread protectors
Technical field:
The utility model belongs to a kind of oil well oil conduit or casing threads protective device, particularly a kind of-46 ℃~66 ℃ indeformable continuous de-oiling pipe of not bonding 5kg pulling force, casing tube screw thread protectors of not chapping.
Background technology:
Be at the employed oil pipe in oil extraction in oil field field or sleeve pipe at present and be threaded; under the effect of button square; connection of thread is easily broken to be taken off; usually use threading protectors to be protected; but the not low temperature resistant non-refractory of present employed threading protectors; yielding, easy be full of cracks, easy little easily broken the taking off of the bonding pulling force that bears, application life is short, has increased operating cost.
Summary of the invention:
In order to solve the problem that exists in the background technology; the utility model provides a kind of-46 ℃~66 ℃ indeformable continuous de-oiling pipe of not bonding 5kg pulling force, casing tube screw thread protectors of not chapping, this threading protectors have-46 ℃~66 ℃ indeformable, do not chap, not bonding, characteristics that the 5kg pulling force constantly takes off.
The technical scheme that the utility model adopts is: should-46 ℃~66 ℃ indeformable continuous de-oiling pipes of not bonding 5kg pulling force that do not chap, casing tube screw thread protectors comprise main body; described main body upper end closed lower ending opening; main body inner wall has screw thread; body rim is upwards established annular boss along week; annular boss has one group of corresponding breach; be provided with gauze wire cloth in the main body cylinder, the upper and lower side of gauze wire cloth is fixed with respectively steel ring.
This novel beneficial effect that has is: this threading protectors have-46 ℃~66 ℃ indeformable, do not chap, not bonding, characteristics that the 5kg pulling force constantly takes off, shock resistance.In the situation that does not increase cost, prolonged application life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-main body, 2-steel ring, 3-gauze wire cloth, 4-screw thread, 5-breach.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified: as shown in Figure 1; be somebody's turn to do-46 ℃~66 ℃ indeformable continuous de-oiling pipes of not bonding 5kg pulling force that do not chap; casing tube screw thread protectors comprises main body 1; main body 1 low temperature resistant subzero 46 ℃; 8h; ovenable roasting 66 ℃; 8h; main body 1 upper end closed lower ending opening; main body 1 inwall has screw thread 4; annular boss is upwards established along week in main body 1 edge; annular boss has one group of corresponding breach 5; to be stuck in breach 5 interior for convenience detach in dismounting during dismounting; be provided with gauze wire cloth 3 in main body 1 cylinder, the upper and lower side of gauze wire cloth 3 is fixed with respectively steel ring 2.Gauze wire cloth 3 and steel ring 2 have increased the intensity of protector, make the protector shock resistance, constantly take off.
