Abstract
The utility model relates to pipe technology fields, title is outer folding edge coiling steel pipe, including steel pipe body, the steel pipe body is coiled to form with steel plate, material used is the steel plate of strip, the connecting portion that steel plate coiling more weeks are formed between helical form, the steel plate between adjacent week, which is welded, coils steel pipe, and hurricane band is presented in connecting portion；It is characterized in that: the steel plate side face has the folded edges of flanging type, folded edges are the connecting portions between steel plate, and the flanging position is arranged in the two sides of steel plate, and the flap is located at the outside of steel plate ontology.Such coiling steel pipe has the advantages that firm welding, not easy to crack.
Description
Technical field
The utility model relates to pipe technology fields, concretely relate to coiling steel pipe.
Background technique
Coiling steel pipe includes steel pipe body, and the steel pipe body is coiled to form with steel plate, and material used is strip
The steel plate of shape, the more week formation helical forms of steel plate coiling, steel plate contact site adjacent between week are welded and coil steel pipe；It is existing
In technology, coiling side edge of steel plate used in steel pipe does not have flanging, i.e. steel plate is smooth, and what welding position relied on is side welding
Together, in general the finite thickness of steel plate, such steel pipe have not prison welding, have the shortcomings that be easy to snap.
Summary of the invention
The purpose of the present invention is to disadvantages mentioned above, a kind of firm welding, coiling steel pipe not easy to crack are provided ---
Outer folding edge coils steel pipe.
The object of the present invention is achieved like this: outer folding edge coils steel pipe, including steel pipe body, the steel pipe body are
It is coiled to form with steel plate, material used is the steel plate of strip, forms helical form, between adjacent week in steel plate coiling more weeks
Connecting portion between steel plate, which is welded, coils steel pipe, and hurricane band is presented in connecting portion；It is characterized in that: the steel plate side mask
There are the folded edges of flanging type, folded edges are the connecting portions between steel plate.
Further speaking, the flanging position is arranged in the two sides of steel plate.
Further speaking, the flap is located at the outside of steel plate ontology.
Further speaking, the angle at the flanging position and steel plate centre position is 85~87 °.
The beneficial effects of the present invention are: such coiling steel pipe has the advantages that firm welding, not easy to crack；
The flanging position is arranged in the two sides of steel plate, and the flanging position is located at the outside of steel plate ontology, has
The more preferable advantage of said effect；
85~87 ° of angle is presented in position among the flanging position and steel plate, has the advantages that welding is stronger.
Detailed description of the invention
Fig. 1 is the side schematic view with the utility model.
Fig. 2 is A-part A diagrammatic cross-section in Fig. 1.
Fig. 3 is the schematic cross-section of one block of steel plate.
Wherein: 1, steel pipe body 2, steel plate 3, folded edges.
The angle at position among α --- flanging position and steel plate.
Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, 2, outer folding edge coils steel pipe, including steel pipe body 1, the steel pipe body be with steel plate coiling and
At material used is the steel plate 2 of strip, is formed between helical form, the steel plate between adjacent week in steel plate coiling more weeks
Connecting portion, which is welded, coils steel pipe, and hurricane band is presented in connecting portion；It is characterized in that: the steel plate side face has flanging type
Folded edges 3, folded edges are the connecting portions between steel plate.
The area of the thus width equivalent to increase welding position, welding is more, and in addition folded edges, which are formed, reinforces
Muscle is also beneficial to increase the bearing strength of steel pipe.
Further speaking, the flanging position is arranged in the two sides of steel plate, as shown in Figure 3.If the not steel of flanging
Plate welding is that flanging is not aspectant welding for the welding of Line To Line, then a flanging and one, then the weldering at two flanging positions
Connecing is aspectant welding, and connection area is bigger, is connected stronger.
Further speaking, the flap is located at the outside of steel plate ontology, as shown in Figure 2.
Further speaking, the angle at the flanging position and steel plate centre position is 85~87 °, as shown in Figure 3.
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.
