Abstract
The utility model relates to a friction welding type outer thickening oil pipe, which is used for oilfield and solves the problem of high cost of the oil pipe. The utility model is characterized in that both ends of a pipe body (2) are provided with outer thickening joints (1) by friction welding (3). The utility model has the characteristics of big bearing pressure and big pulling force. Simultaneously, the positions of the joints are not easy to break, unnecessary loss is avoided, and therefore, large amounts of time and maintenance cost can be saved.
Description
Technical field:
The utility model relates to the oil field and recovers the oil and the used a kind of oil pipe in water filling aspect, belongs to a kind of friction welding formula external upset tubing.
Background technology:
The oil field is in the oil exploitation process, and oil recovery and the used pipe in water filling aspect mostly are oil pipe greatly, and consumption is very big.Oil pipe commonly used at present mostly is seamless steel pipe greatly, mainly is abutted against head between the steel pipe and is connected, and owing to the wearing and tearing in use of joint screw thread, makes and ruptures easily at the oil connection place, causes the waste in the production.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of above-mentioned technology and not a kind of friction welding formula external upset tubing of easy fracture of oil connection place is provided.
The technical scheme that the utility model adopted is: this friction welding formula external upset tubing, form body two ends friction welding external upset (EU) joint by body and joint.
The utility model beneficial effect compared with the prior art is: owing to use friction welding external upset (EU) joint at the body two ends, make joint can adapt to the performance of external upset tubing, can bear the different needs of pressure and pulling force, satisfy the production in oil field, simultaneously also be difficult for rupturing in the joint, avoid unnecessary loss, have considerable economic.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1-external upset (EU) joint, 2-steel tube body, 3-friction welding.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this oil pipe is made up of body 2 and joint 1, use friction welding 3 external upset (EU) joints 1 at body 2 two ends, make joint 1 can adapt to the performance of external upset tubing, can bear the different needs of pressure and pulling force, satisfy the production in oil field, easy fracture not simultaneously at joint 1 place, avoid unnecessary loss, thereby can save a large amount of man-hours and maintenance cost, have considerable economic.
During actual the use, use identical with conventional oil pipe.
Claims (1)
1, the used a kind of friction welding formula external upset tubing in oil field is made up of body (2) and joint (1), it is characterized in that: body (2) two ends friction welding (3) external upset (EU) joint (1).
