Description
Technical field
The utility model relates to pipe technology fields, concretely relate to coiling steel pipe.
Background technique
Steel, which coils steel pipe, to be coiled to form with steel plate, and material used is the steel plate of strip, the more all shapes of steel plate coiling
Gap (junction) is formed between the steel plate in spiral, adjacent week, gap weldig is formed into coiling steel pipe；In the prior art,
The edge of coiling steel pipe does not have the setting of upsetting thickness, and the thickness of entire steel plate everywhere is the same, in this way, since edge connects
The area of touching is smaller, there is the shortcomings that the welding is not firm, affects the quality of steel pipe.
Summary of the invention
The purpose of the present invention is to disadvantages mentioned above, provide a kind of welding position be connected firmly, the steel of good product quality
System coiling steel pipe-edge upsetting thickness steel coiled tubing.
The object of the present invention is achieved like this: the steel coiled tubing of edge upsetting thickness, including steel pipe body, the steel
Tube body is coiled to form with steel plate, and material used is the steel plate of strip, forms helical form, adjacent week in steel plate coiling more weeks
Steel plate between form gap, by gap weldig into coiling steel pipe；It is characterized in that: the side edge of steel plate position has upsetting thick
Structure, upsetting thickness structure side edge of steel plate formed plane-shaped structure.
Further speaking, the structure of the upsetting thickness is arranged in steel pipe body side.
Further speaking, the structure of the upsetting thickness is arranged in steel pipe body two sides.
Further speaking, after the upsetting structure be triangle structure.
Further speaking, the width outside the upsetting thickness structure is 1.5-2 times of part thickness among steel pipe body.
The beneficial effects of the present invention are: the steel coiled tubing of such edge upsetting thickness have welding position be connected firmly,
The advantages of good product quality；
The structure of the upsetting thickness is arranged in steel pipe body side, has the advantages that the steel pipe side formed is more regular；
The structure of the upsetting thickness is arranged in steel pipe body two sides, has the advantages that the steel pipe formed connection is stronger；
The upsetting thickness structure is the structure of triangle, has the advantages that the steel pipe formed is more smooth；
Width outside the upsetting thickness structure is 1.5-2 times of part thickness among steel pipe body, has and guarantees steel pipe
Welding position is connected firmly, the effect of good product quality.
Detailed description of the invention
Fig. 1 is the side schematic view with the utility model.
Fig. 2 is the part A enlarged diagram in Fig. 1.
Fig. 3 is B-B diagrammatic cross-section in Fig. 2 (a kind of situation).
Fig. 4 is B-B diagrammatic cross-section in Fig. 2 (another situation).
Wherein: 1, steel plate 2, gap 3, upsetting thickness structure.
Part thickness among width L-steel pipe body outside D-upsetting thickness structure.
Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown in Figure 1,2,3, 4, the steel coiled tubing of edge upsetting thickness, including steel pipe body, the steel pipe body are
It is coiled to form with steel plate 1, material used is the steel plate of strip, forms helical form, the steel plate in adjacent week in steel plate coiling more weeks
Between formed gap 2, by gap weldig into coiling steel pipe；It is characterized in that: the side edge of steel plate position has the knot of upsetting thickness
Structure 3, upsetting thickness structure form plane-shaped structure in side edge of steel plate.
The structure of upsetting thickness can thicken, such side edge of steel plate position in upsetting thickness equipment by side edge of steel plate position upsetting thickness
Thickness increases, and the depth of welded gaps increases, and what is filled inside gap site is solder, increases the fastness of this steel pipe, can
To realize the purpose of this utility model.
Further speaking, the structure of the upsetting thickness is arranged in steel pipe body side.Such as upsetting thickness structure setting is existed
The outside of steel pipe, then steel duct is smooth, meets some requirements used.
Further speaking, the structure of the upsetting thickness is arranged in steel pipe body two sides.It is easier to carry out steel pipe in this way
Upsetting is thick, and cost is lower.
Further speaking, the upsetting thickness structure is the structure of triangle.
Further speaking, the width D outside the upsetting thickness structure is 1.5-2 of part thickness L among steel pipe body
Times.Guarantee the effect of upsetting thickness in this way.
Above is only a specific embodiment of the present invention, but structure feature of the invention is not limited to this, any ability
Within the field of the present invention, made changes or modifications all cover in the scope of the patents of the invention the technical staff in domain.
