Abstract
The utility model provides an integral upset drill rod. The integral upset drill rod is composed of a joint and a pipe body, wherein the joint is arranged at one end of the pipe body, an upset layer is arranged at the lower part of the pipe body, and the integral upset method is adopted for the head part of the drill rod. The integral upset drill rod has the advantages that the difficult of the upset position is reduced, and the quality problems of eddy flow, puncture and leakage.
Description
Technical field
The utility model relates to a kind of drilling rod, is specifically related to a kind of whole thickening drilling rod.
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 difficulty in thickening post, and take place turbulent easily, 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 whole thickening drilling rod.
Technical solution adopted in the utility model is: a kind of whole thickening drilling rod, to form by joint and body, and an end of body is provided with joint, is provided with thickening layer in the bottom of body, and the drilling rod head adopts the mode of whole thickening.
The beneficial effects of the utility model are: reduced the difficulty in thickening post, avoided turbulent flow, pierced 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, 3 thickening layers.
The specific embodiment
