Description
Technical field
The utility model belongs to the production equipment field of double-wall pipe, more specifically to a kind of flange welding of double-wall pipe
Tooling.
Background technique
There are ultralow temperature pipeline in the storage of ship LNG host fuel and feed system (design temperature is -165 DEG C).Mesh
The preceding pipeline for the temperature grade, is all made of stainless steel tube outsourcing heat preservation insulating materials to carry out the conveying of cryogenic media, this
There are problems for method, such as are difficult to detect to the leakage of pipeline；There are the manifold volumes of outsourcing insulation excessively to expand, and is easy old
Change, damage.
Some also uses double-wall pipe on ship, and using is that multistage double-wall pipe is mutually spliced by flange
At wherein flange need to be welded with the inner and outer tubes of double-wall pipe, and need to guarantee that flange is coaxial with double-wall pipe, to prevent
The flange of adjacent two double-wall pipe can not dock, but at present without dedicated welding tooling, and flange easily inclines with double-wall pipe when welding
Tiltedly, error is larger.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of one placement double-walled of structure autocracy according to double-wall pipe
Area under control domain concurrently sets placement flange region, and double-wall pipe and flange, which are fixed on corresponding position i.e., before welding can weld, welding
Both processes are stablized, the flange weld tooling of the high double-wall pipe of welding quality.
To achieve the above object, the utility model provides following technical solution: a kind of flange weld tooling of double-wall pipe,
Including bottom plate, it is provided with several support plates on the bottom plate, the supporting plate of several bracketing double-wall pipes, institute are provided in the support plate
It states and is additionally provided with fashioned iron on bottom plate, the locking hole with flange cooperation is offered on the fashioned iron and bottom plate.
The further supporting plate surface is provided with anti-skidding cushion.
The further anti-skidding cushion is rubber pad.
The further supporting plate is equipped with holding tank, and rubber mat component is placed in holding tank.
The further support plate and fashioned iron are welded on bottom plate, and the supporting plate welding is on the supporting plate.
Compared with prior art, the utility model has the beneficial effects that double-wall pipe is placed on all supporting plates, flange passes through
Bolt is fixed on fashioned iron and bottom plate, and relative position locating for flange and double-wall pipe both is to need weld at this time, angle and
Position is fixed, and staff directly welds, and welding process is stablized, and Product jointing quality is high, and rubber pad can prevent
Double-wall pipe surface abrasion prevents its sliding transfer simultaneously.

Specific embodiment
It is described further referring to figs. 1 to embodiment of the Fig. 4 to the flange weld tooling of the utility model double-wall pipe.
A kind of flange weld tooling of double-wall pipe, including bottom plate 1 are provided with several support plates 2 on the bottom plate 1, described
It is provided with the supporting plate 3 of several bracketing double-wall pipes 6 in support plate 2, fashioned iron 4, the fashioned iron 4 and bottom are additionally provided on the bottom plate 1
The locking hole 7 cooperated with flange 5 is offered on plate 1.
Wherein the support plate 2 and fashioned iron 4 are welded on bottom plate 1, and the supporting plate 3 is welded in support plate 2, and bottom plate 1,
Support plate 2, fashioned iron 4 and supporting plate 3 are all made of Stainless steel 316 L material.
As shown in Figure 1-3, the case where bending is all had in entire space certainly for double-wall pipe 6 in the present embodiment,
Double-wall pipe 6 is directly placed on ground and welds, and double-wall pipe 6 itself is difficult to keep one and holds position, while flange 5 is heavier, and method
Orchid 5 needs to weld inner tube and is also required to welding outer tube, and higher to required precision, directly worker is greatly challenged in welding, and matter
Amount is not easy to guarantee.
Wherein the setting of support plate 2 makes according to the shape profiling of double-wall pipe 6, so that when double-wall pipe 6 is fixed, just
It can be matched with supporting plate 3, all supporting plates 3 can hold double-wall pipe 6, and the upper surface of supporting plate 3 then uses semi-cylindrical canyon shape,
Double-wall pipe 6 is embedded, flange 5 is passed through into the locking hole 7 on 4/ bottom plate 1 of screw bolt passes flange 5 and fashioned iron,
Flange 5 is fixed on fashioned iron 4 and bottom plate 1 to (locking hole 7 can be through-hole, be cooperated at this time using nuts and bolt, locking hole 7
Can be screw hole, at this time without nut), that is, it is placed at the both ends of double-wall pipe 6, flange 5 is fixed on fashioned iron 4 completely
It on bottom plate 1, can not move, in welding, first directly weld the inner tube of double-wall pipe 6 and flange 5, after the completion, recycle
Huff pipe is welded the outer tube of double-wall pipe 6 and flange 5, and entire welding process double-wall pipe 6 and flange 5 keep opposite
It stands, avoids the case where being displaced in the welding process, and without helping double-wall pipe 6 or flange always in worker's welding process
5, and without having to worry about alignment accuracy problem, labor intensity is lower, and welding efficiency is high.
Preferably 3 surface of supporting plate is provided with anti-skidding cushion to the present embodiment, and the preferred anti-skidding cushion is rubber
Other materials also may be selected in rubber mat 8 certainly, and rubber pad 8 is at low cost easy to use, and the outer wall that can be avoided double-wall pipe 6 first connects
Touching supporting plate 3 causes to scratch, and secondly can prevent double-wall pipe 6 from sliding occurs or roll phenomenon.
Preferably the supporting plate 3 is equipped with holding tank 38 to the present embodiment, and rubber pad 8 is partially disposed in holding tank 38, i.e.,
There is part to be located above holding tank 38 and protrudes supporting plate 3, it can be by rubber pad 8 when the elastic weaker or surface dirt of rubber pad 8 is more
It is removed by holding tank 38, facilitates and replaced；Rubber pad 8 can prevent it by falling off naturally on supporting plate 3 in holding tank 38.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
