Abstract
The invention discloses a coiled material for an embedded metal spiral seam pipe, which is characterized in that protruded tenons are arranged along an edge at one side of each metal strap, the width at the outer end of each tenon is larger than that at the root of each tenon, both the edge of each tenon and the junction of each tenon and each metal strap are in curved transition, openings with the same shape as the tenons are arranged along an edge at the other end of each metal strap, the length between the adjacent tenons is one/integer of a unit spiral length, the value of the integer ranges from 4 to 10, the unit spiral length is the length that each metal strap is bent into one circle of the pipe along a spiral path, the metal strap is bent along the spiral path, the tenons and the openings between the adjacent spiral metal straps are coincided in a one-to-one correspondence way and are welded together, the ratio of the height to the maximum width of each tenon is 0.7-1.3, and the height of each tenon is 1/20 to 1/10 of the width of each metal strap. The coiled material disclosed by the invention can be directly bent and welded along a preset spiral track to form the pipe, and part of stress is borne by a wave peak part of each metal strap, so that the reliability is improved.
Description
Technical field
The present invention relates to a kind of metallic conduit for spiral weld make coiled material, more particularly to a kind of embedded gold
Belong to the effective coiled material of spiral weld.
Background technology
Often use feed-line in the industrial production, as larger in the field such as heating power, tap 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 effective coiled material of embedded metal spiral weld.
The technical solution used in the present invention is：A kind of effective coiled material of embedded metal spiral weld, including being wrapped in reel
On metal tape it is characterised in that being arranged with prominent tenon, tenon outer end along this edge on lateral edges of shown metal tape
Width is more than tenon root width, tenon edge and be curve transition, another side of metal tape with metal tape junction
Be arranged with and tenon shape identical gap along this edge on edge, between adjacent tenon between divide it for the integer of unit helix length
One, its integer numerical value is 4 to 10, and unit helix length is that metal tape bends to the length of pipe one circle, metal tape along spiral path
Along spiral path bending, the tenon of adjoining spiral metal interband and gap correspond and coincide and seam, and tenon height is with it
Large width-radius ratio value is 0.7 to 1.3, and 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 after described tenon embeds gap between neighboring edge.
Coiled material of the present invention directly can be curled into pipe along default helical trajectory, adjoining spiral metal interband in coiling process
Tenon mutually embedding with groove, the weld seam general direction of embedded welded steel pipes remains spiral, is suitable to make longer pipe
Road, the tenon of adjoining spiral metal interband and groove correspond and coincide and seam, thus change original straight weldering
Seam, is changed into along the staggered weld seam of spiral fluctuation, when being stressed, stress in welded joints while act also on gold
Belonging to the staggered crest position of band, bearing part stress is shared at metal tape crest position, thus reducing the stress of commissure, reducing weldering
The probability going wrong at seam, because tenon outer end width is more than tenon root width, tenon and coincideing of groove can utilize
The very high axial tensile property of interaction between body, improves reliability, meets highly reliable requirement, particularly axial tension will
Ask high place.
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 effective coiled material of embedded metal spiral weld includes being wrapped on reel the embodiment of the present invention
Metal tape 1, metal tape is solderable metal, the such as material such as ferrum, copper, aluminum, and the present embodiment is steel, meets different helical pipes
Requirement, the parameter such as its wall thickness width can more be actually needed customization, arrange along this edge on lateral edges of metal tape
There is prominent tenon, tenon outer end width is more than tenon root width, tenon edge and be curve with metal tape junction
Transition, can improve tear resistance, another lateral edges of metal tape are arranged with along this edge and slit with tenon shape identical
Mouthful, between adjacent tenon between for unit helix length integer divide one, its integer numerical value is 4 to 10, and unit helix length is
Metal tape bends to the length of pipe one circle along spiral path, and metal tape bends to tubulose, adjoining spiral metal tape along spiral path
Between tenon and gap correspond and coincide and seam forms spiral weld steel pipe 4, the spacing of adjacent tenon can be according to wanting
The caliber of prepared serpentine pipe and helical angle are calculated, as long as the gap marginal position that opposite side is engaged with it can be with its enough kiss
Close can it is also possible to calculate by caliber and helical angle, be not have to both sides aligned fashion, only need to meet to engage one by one and be
Can, 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 share stress, weld seam is not long simultaneously, tenon height be metal bandwidth degree 1/10th to ten/20th so as to
Between ratio 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 edge
Between can possess gap less than 0.6 millimeter, not only favourable and embedded but also suitable weld seam can be provided.
Coiled material of the present invention directly can be curled into pipe along default helical trajectory, adjoining spiral metal interband in coiling process
Tenon mutually embedding with groove, the weld seam general direction of embedded welded steel pipes remains spiral, is suitable to make longer pipe
Road, the tenon of adjoining spiral metal interband and groove correspond and coincide and seam, thus change original straight weldering
Seam, is changed into along the staggered weld seam of spiral fluctuation, when being stressed, stress in welded joints while act also on gold
Belonging to the staggered crest position of band, bearing part stress is shared at metal tape crest position, thus reducing the stress of commissure, reducing weldering
The probability going wrong at seam, because tenon outer end width is more than tenon root width, tenon and coincideing of groove can utilize
The very high axial tensile property of interaction between body, improves reliability, meets highly reliable requirement, particularly axial tension will
Ask high place.
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.
