Abstract
The utility model provides an integral straightly-connected and thickened drilling rod comprising joints and a pipe body which has joints arranged at both ends. A joint part is formed by directly thickening the joint on the periphery thereof. No weld seam exists between the joints and the pipe body, and the pipe body and the joints are made of metallic materials. The integral straightly-connected and thickened drilling rod is advantageous in that the strength of the joints is improved, and no weld is needed. The pipe body and the joints are made of same materials, which improves the strength of an integral drill rod and prevents the quality problems of turbulent flow, penetration and piercing leakage.
Description
Technical field
The utility model relates to a kind of drilling rod, is specifically related to the direct-connected thickening drilling rod of a kind of integral body.
Background technology
Drilling rod is to carry out the two ends thickening by seamless steel pipe at present, and then the joint that has external screw thread and internal thread is welded at two ends respectively, for the intensity that guarantees weld seam will be by increasing the intensity that cross-sectional area guarantees drilling rod, so just increased the thickness of joint, reduced stem weight, joint and body also are not identical material, and easily turbulent flow take place, pierce through quality problems such as thorn leakage.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of integral body direct-connected thickening drilling rod.
Technical solution adopted in the utility model is: the direct-connected thickening drilling rod of a kind of integral body, to form by joint and body, and the two ends of body are provided with joint, and joint area is to form by directly thickening around the joint, does not have weld seam between described joint and the body.
Body and joint adopt metal material to make.
The beneficial effects of the utility model are: strengthened strength of joint, need not weld, thereby joint and body adopt same material to strengthen the intensity of whole drilling rod, have avoided turbulent flow, pierce through, the quality problems that thorn leaks.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1 joint, 2 bodys.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, the direct-connected thickening drilling rod of a kind of integral body is made up of joint 1 and body 2, and the two ends of body 2 are provided with joint 1, and joint 1 position is to form by directly thickening around the joint 1, does not have weld seam between described joint 1 and the body 2.
Claims (2)
1. the direct-connected thickening drilling rod of integral body is made up of joint and body, it is characterized in that the two ends of body are provided with joint, and joint area is to form by directly thickening around the joint, does not have weld seam between described joint and the body.
2. the direct-connected thickening drilling rod of a kind of integral body according to claim 1 is characterized in that body and joint adopt metal material to make.
