Abstract
The invention discloses an embedded weld joint steel pipe. The embedded weld joint steel pipe is characterized in that a metal band is included; protruding tenons are arranged on the edge of one side of the metal band along the edge; the width of the outer end of each tenon is larger than that of the root of the tenon; the connecting position of the edge of each tenon and the metal band is in curved transition; openings the same as the tenons are formed in the edge of the other side of the metal band along the edge; the metal band is bent along a spiral path; the adjacent tenons and openings between spirals of the metal band are matched and welded in one-to-one correspondence; the number of tenons and openings matched on a metal band weld joint on a circle of spiral is four pairs to eight pairs; the ratio of the height to the maximum width of each tenon ranges from 0.7 to 1.3; and the height of each tenon is 1/20-1/10 of the width of the metal band. When the embedded weld joint steel pipe bears stress, the stress acts on the weld joints and meanwhile acts on the staggered crest portions of the metal band, and the axial tensile property can be improved through interaction of bodies via matching of the tenons and the grooves.
Description
Technical field
The present invention relates to a kind of metallic conduit of spiral weld, more particularly to a kind of embedded welded steel pipes.
Background technology
Often use feed-line in the industrial production, as larger in the field such as heating power, running water, oil, natural gas size
Pipeline, the also small size pipeline such as cable sheath tube, all long during these pipe applications, typically all adopt spiral weld
Pipe, by causing stress all ratios of deformation larger after either being transported or installed due to longer dimension, the tension of its weld seam is strong
Degree just seems most important, is axial pulling force by it, is the key point of spiral-selded pipe quality assurance, existing spiral welding
The weld seam of slit-tube is exactly one and is concentrated mainly on commissure during by distortional stress along spiralling normal spiral weld seam, holds
Easily go wrong in commissure, still await technological innovation and solve.
Content of the invention
In order to solve the above problems, the invention provides a kind of embedded welded steel pipes.
The technical solution used in the present invention is：A kind of embedded welded steel pipes are it is characterised in that include metal tape, metal tape
Lateral edges on be arranged with prominent tenon along this edge, tenon outer end width be more than tenon root width, tenon edge with
And it is curve transition with metal tape junction, another lateral edges of metal tape are arranged with identical with tenon shape along this edge
Gap, metal tape bends along spiral path, and the tenon of adjoining spiral metal interband and gap correspond and coincide and seam, one
On metal tape weld seam on circle spiral, the tenon coincideing and gap are right for 4 to 8, and tenon height and its Breadth Maximum ratio are 0.7
To 1.3, tenon height is 1st/10th to ten/20th of metal bandwidth degree.
Further, the edge Dao You oblique angle of the tenon on described metal tape and groove.
Further, possess the gap less than 0.6 millimeter between described tenon and gap edge.
The weld seam general direction of the embedded welded steel pipes of the present invention remains spiral, is suitable to make longer pipeline,
It is respectively provided with tenon and groove along spiral weld in both sides metal strip edge, the tenon of adjoining spiral metal interband and groove are one by one
Corresponding identical simultaneously seam, thus changes original straight weld seam, is changed into, along the staggered weld seam of spiral fluctuation, being subject to answer
When power, stress in welded joints while act also on metal tape interlock crest position, metal tape crest position is divided
Load bearing part stress, thus reducing the stress of commissure, reduces the probability that commissure goes wrong, due to tenon outer end width
More than tenon root width, the very high axial tensile property of interaction that can utilize between body of coincideing of tenon and groove,
Improve reliability, meet highly reliable requirement, place that particularly axial tension has high demands.
Brief description
Fig. 1 makes pipe schematic diagram for the embodiment of the present invention.
Fig. 2 implements schematic diagram after plate cutting for the present invention.
Reference:1 metal tape；2 tenons；3 gap；4 spiral weld steel pipes.
Specific embodiment
As shown in Figure 1, 2, this embedded welded steel pipes includes metal tape 1 to the embodiment of the present invention, and the big material of metal tape is permissible
Select as needed, the steel plate of heavy wall can be adopted in the larger-size pipeline in the fields such as heating power, running water, oil, natural gas,
Can be using relatively thin steel plate when for cable sheath tube, can be using the good conjunction of some shielding properties when needing to shield
Golden material, as shown in Fig. 2 being arranged with prominent tenon 2, tenon outer end width along this edge on lateral edges of metal tape after cutting
Degree is more than tenon root width, tenon edge and be curve transition with metal tape junction, can improve tear resistance,
It is arranged with and tenon shape identical gap 3 along this edge on another lateral edges of metal tape, metal tape bends along spiral path
Become tubulose, the tenon of adjoining spiral metal interband and gap to correspond to coincide and seam formation spiral weld steel pipe, a circle spiral shell
The tenon coincideing on the metal tape weld seam screwing on and gap are 4 to 8 right, and the spacing that tenon or gap are said can be according to caliber and spiral shell
Swing angle calculates, and tenon or gap position can determine according to helical angle, and a circle helix length is the integer of spacing between tenon
Times, tenon height and its Breadth Maximum ratio are 0.7 to 1.3 so as to staggered position has suitable depth, can preferably hold
Carry and share stress, weld seam is not long simultaneously, tenon height is between 1st/10th to ten/20th of metal bandwidth degree,
Make ratio therebetween tend to moderate, welding demand can be met at the edge Dao You oblique angle of the just profound waveform of metal tape；Tenon and gap
The gap less than 0.6 millimeter can be possessed between edge, not only favorably can provide suitable weld seam with embedding.
The weld seam general direction of the embedded welded steel pipes of the present invention remains spiral, is suitable to make longer pipeline,
It is respectively provided with tenon and groove along spiral weld in both sides metal strip edge, the tenon of adjoining spiral metal interband and groove are one by one
Corresponding identical simultaneously seam, thus changes original straight weld seam, is changed into, along the staggered weld seam of spiral fluctuation, being subject to answer
When power, stress in welded joints while act also on metal tape interlock crest position, metal tape crest position is divided
Load bearing part stress, thus reducing the stress of commissure, reduces the probability that commissure goes wrong, due to tenon outer end width
More than tenon root width, the very high axial tensile property of interaction that can utilize between body of coincideing of tenon and groove,
Improve reliability, meet highly reliable requirement, place that particularly axial tension has high demands.
It is only present pre-ferred embodiments in sum, all equivalent modifications done according to the application and prior art are added all
It is considered as the technology of the present invention category.
