Abstract
The utility model provides a drilling rod made with a narrow gap welding technique. The drilling rod includes a pipe body equipped with an upper thickened end and a lower thickened end. The upper thickened end of the pipe body is welded with a female coupling through a welding wire. The lower thickened end of the pipe body is welded with a male coupling through a welding wire. Compared to the prior art, the drilling rod in the utility model has advantages of simple structure, low equipment investment, low manufacturing cost, great welding seam strength, long service lifetime and the like. And the drilling rod has a longer inner thickened transitional zone, thus, the phenomenon that the pipe body is pierced or broken is avoided. Moreover, when the couplings are worn, the worn couplings can be replaced with new couplings conveniently. The repeated utilization rate of the drilling rod is high. The drilling rod in the utility model can be widely applied to petroleum and natural gas drilling and non-excavation fields.
Description
One, technical field
The utility model relates to the drilling rod that a kind of oil, gas drilling and non-excavation use, and is a kind of narrow gap welding stacks concretely.
Two, background technology
At present, in oil, gas drilling and non-excavating construction process, drilling rod is the drilling tool that generally uses, and also is topmost cost input, and the height in drilling rod cost and application life directly influences the construction economy benefit.Common drilling rod processing and manufacturing adds row complicated procedures of forming such as tempering by friction welding, weld seam quenching, equipment drops into relative with manufacturing cost higher, it is lower that friction welding is accepted wall thickness restriction welding zone comprehensive strength, and it is relatively poor to repeat weldability, interior crassitude intermediate belt length is not enough, occurs easily piercing through even rupturing in drilling process.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, narrow gap welding stacks that recycling rate of waterused is high is provided.
Its technical scheme is: comprise body, the body two ends are respectively equipped with upset end and following upset end, and the last upset end of body is welded to connect by welding wire and female adapter, and the following upset end of body is welded to connect by welding wire and male connection.
The utility model compared with prior art, have that crassitude intermediate belt simple in structure, easy to connect, with low cost, interior is longer avoids occurring the advantage that body pierces through phenomenon of rupture, weld strength height, long service life, and can continue welding after joint uses and weares and teares and more renew joint, simple operation, recycling rate of waterused height, be convenient in oil, gas drilling and the field extensive use of non-excavation.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
As shown in the figure, a kind of narrow gap welding stacks, comprise body 1, the thickening of body 1 two ends, upset end 2 is welded to connect welding wire 6 and female adapter 4 by the narrow clearance melting electrode pulsed argon arc welding on the body 1,1 time upset end 3 of body makes welding wire 7 and male connection 5 welding by the narrow clearance melting electrode pulsed argon arc welding, when female adapter 4 and male connection 5 thread abrasions can't continue to repair when using, only needs the joint excision welded with new joint by narrow gap welding silk 6 and continues to come into operation.
Claims (1)
1. narrow gap welding stacks, comprise body, it is characterized in that: the body two ends are respectively equipped with upset end and following upset end, and the last upset end of body is welded to connect by welding wire and female adapter, and the following upset end of body is welded to connect by welding wire and male connection.
