Abstract
A kind of composite pipe and tube groove form, including basic unit, the outside of described basic unit is provided with composite bed, it is provided with groove on described composite bed, being provided with layer A at described groove, the inner side of described layer A is provided with layer B, and the inner side of described layer B is provided with layer C；The present invention has advantage rational in infrastructure, easy to process, that welding quality is good, work efficiency is high, safety is high.
Description
Technical field
The present invention relates to Machining Technology field, be specially a kind of composite pipe and tube groove form.
Background technology
In recent years, along with developing rapidly that oil, natural gas, chemical industry, boats and ships are developed, corrosive pipeline environment is to conveyance conduit
Proposing corrosion-resistant requirement higher, more stringent, at present great majority be bimetallic pipeline, and corrosion-resistant, wearability especially by force, is fitted
Answer the aspects such as the conveying of Yu Haiyang, oil, chemical industry, medicine, electric power, natural gas, aerospace industry, shipbuilding, but bimetallic
Pipeline is divided into basic unit and composite bed two parts, when the pipe fitting diameter difference of pipeline in critical field and group to weld bond misalignment reach
During 0-4mm, composite bed thickness only has 2-4mm, and when pipeline and pipe fitting are all in critical field, unfitness of butt is 4mm to the maximum,
So effective thickness of composite bed welding only has 0-2mm, and sometimes because positive and negative values impact causes misalignment serious, composite bed is effective
Thickness is 0, so causes the welding of composite bed and basic unit, cause pipeline girth joint run after reveal consequence extremely serious,
And causing weld seam material to change, the decay resistance of weld seam the most greatly declines；Such as (when the nominal diameter of pipe fitting is at 650-
When 750, inner end diameter size is ± 2.0, and in critical field, 4 values of positive good job between+2 and-2, composite bed thickness is only 2-
4mm, it is easy to cause misalignment phenomenon) in the past in order to make up this kind of defect, the can be carried out in the good basic unit of groove and composite bed
The overlay cladding of secondary operations groove 2-4mm, material is nickel-base alloy or rustless steel, but material so can be caused to waste, and man-hour is unrestrained
Take；Therefore it provides a kind of built-up welding pipe fitting rational in infrastructure, easy to process, that welding quality is good, work efficiency is high, safety is high is multiple
Layer divided edge structure is necessary.
Summary of the invention
It is an object of the invention to provide a kind of composite pipe and tube groove form, to solve above-mentioned background technology carries
The problem gone out.
For achieving the above object, a kind of composite pipe and tube groove form, including basic unit, the outside of described basic unit sets
It is equipped with composite bed, described composite bed is provided with groove, at described groove, be provided with layer A, the inner side of described layer A
Being provided with layer B, the inner side of described layer B is provided with layer C.
The angle of described groove is 60-75 °.
Compared with prior art, the invention has the beneficial effects as follows: the present invention in use, first by the thickness at composite bed groove
Degree removes 0.5mm, has 4mm to show money or valuables one carries unintentionally, and the width dimensions of groove is constant, then uses the TIG that fills silk, bead welding wire to use
ERNiCrMo-3, φ 1.2mm welding wire, carries out built-up welding, first built-up welding layer C, then uses ERNiCrMo-3, φ 2.4mm or φ
3.2mm or φ 4.0 welding rod built-up welding layer B and layer A, does RT detection and confirms zero defect after having welded, operation of the present invention simplifies,
Cost is relatively low, and ensure that circumferential weld installation quality；The present invention have rational in infrastructure, easy to process, welding quality is good, work effect
The advantage that rate is high, safety is high.
Accompanying drawing explanation
Fig. 1 is the structural representation after a kind of composite pipe of the present invention and the welding of tube groove form.
Fig. 2 is the structural representation before a kind of composite pipe of the present invention and the welding of tube groove form.
In figure: 1, basic unit 2, composite bed 3, layer A 4, layer B 5, layer C 6, groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1-2, a kind of composite pipe and tube groove form, including basic unit 1, the outside of described basic unit 1 sets
It is equipped with composite bed 2, described composite bed 2 is provided with groove 6, at described groove 6, be provided with layer A3, described layer A3
Inner side be provided with layer B4, the inner side of described layer B4 is provided with layer C5.
The angle of described groove 6 is 60-75 °.
Thickness at composite bed groove in use, is first removed 0.5mm, has 4mm to show money or valuables one carries unintentionally by the present invention, the broad-ruler of groove
Very little constant, then use the TIG that fills silk, bead welding wire uses ERNiCrMo-3, φ 1.2mm welding wire, carries out built-up welding, first built-up welding layer
C, then uses ERNiCrMo-3, φ 2.4mm or φ 3.2mm or φ 4.0 welding rod built-up welding layer B and layer A, does after having welded
RT detection confirms zero defect, and operation of the present invention simplifies, and cost is relatively low, and ensure that circumferential weld installation quality；The present invention has knot
The advantage that structure is reasonable, easy to process, welding quality is good, work efficiency is high, safety is high.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible
Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace
And modification, the scope of the present invention be defined by the appended.
