Description
Technical field
The utility model is related to a kind of non-uniform thickness pipe docking structure, belongs to steel member technical field.
Background technology
In Marine oil and gas resource development process, drilling platforms is mainly used in prying into Oil/gas Well, it can also be used to beat producing well,
Workover treatment, the drilling and producing platform in can also being produced as early stage, the realization of these major functions depends on its special portion
Part：Such as application of spud leg, jacking system, locking device and cantilever beam.With the continuous expansion of drilling platforms scale, to stake
Leg it is also proposed higher requirement, not only need spud leg to have a higher bearing strength, but also will can better against wind,
The influence of the environmental factors such as wave, stream, to be lifted, platform adapts to severe sea condition work capacity and storm deposits ability certainly.
Existing a platform leg product is used, it is necessary to which thick-walled tube is docked with thin-wall circular tube in factory, but is adopted
When being docked with existing welding manner, the merging precision of thick-walled tube and thin-wall circular tube is poor, welds and is inconvenient, influence
Final welding quality and production efficiency, weld strength is poor, it is impossible to the safety in utilization of ocean platform is effectively ensured.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of non-uniform thickness pipe docking for above-mentioned prior art
The merging precision of structure, its thick-walled tube and thin-wall circular tube is good, and welding quality is high, welds very convenient, substantially increases
Production efficiency, joint weld strength is high, can effectively ensure that the safety in utilization of ocean platform.
The technical scheme in the invention for solving the above technical problem is：A kind of non-uniform thickness pipe docking structure, it is wrapped
Thick-walled tube and thin-wall circular tube are included, is connected between the thick-walled tube and thin-wall circular tube by weld seam, the thick-walled tube exists
Commissure is provided with the first groove, and the thin-wall circular tube is provided with the second groove, first groove and the second slope in commissure
The ratio between width of mouth is the ratio between wall thickness of thick-walled tube and thin-wall circular tube, and first groove is stepped, first groove
Including first slope and the second slope, the first slope is located at the inner side on the second slope, the first slope and the second slope
The ratio between width be 2:1, the first slope and the second slope deep equality.
Compared with prior art, the utility model has the advantage of：
The merging precision of a kind of non-uniform thickness pipe docking structure of the utility model, its thick-walled tube and thin-wall circular tube is good, weldering
Connect quality high, weld very convenient, substantially increase production efficiency, joint weld strength is high, can effectively ensure that sea
The safety in utilization of foreign platform.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, a kind of non-uniform thickness pipe docking structure in the present embodiment, it includes thick-walled tube 1 and thin-wall circular
Pipe 2, is connected, the thick-walled tube 1 is provided with weld seam 3 between the thick-walled tube 1 and thin-wall circular tube 2 by weld seam 3
First groove 4, the thin-wall circular tube 2 is provided with the second groove 5, the width of the groove 5 of the first groove 4 and second at weld seam 3
The ratio between degree is the ratio between wall thickness of thick-walled tube 1 and thin-wall circular tube 2, and first groove 4 is stepped, and first groove 4 is wrapped
The slope 4.2 of first slope 4.1 and second is included, the first slope 4.1 is located at the inner side on the second slope 4.2, the first slope
4.1 and second the ratio between the width on slope 4.2 be 2:1, the deep equality of 4.1 and second slope of first slope 4.2.
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
