Abstract
The utility model discloses a butt welding type double sleeve pipeline connection structure, relates to the technical field of design and installation of a vessel pipeline, and comprises a first steelpipe (1), a steel pipe (2), a first sleeve (3), a second sleeve (4) and a bulkhead (5). The first sleeve (3) is sheathed on the outer walls of the first steel pipe (1) and the second steel pipe (2),and the first sleeve (3) is welded with the first steel pipe (1). The second sleeve (4) is sheathed on the outer wall of the second steel pipe (2), and the second sleeve (1) is respectively welded with the second steel pipe (2) and the bulkhead (5). The first sleeve (3) is welded with the second sleeve (4). The butt welding type double sleeve pipeline connection structure has the following beneficial effects that the connection structure saves sleeve, reduces welding seam, decreases the opening size of the through cabin and improves the corrosion resistance of the sleeve.
Description
Technical field
The utility model relates to ship pipeline design and installation technical field, relates in particular to a kind of butt joint type double-bushing pipeline connecting structure.
Background technology
In ship pipeline design and installation process, often use sleeve pipe to connect, exactly adopt the sleeve pipe and the welded connection of the female pipe of main body pipeline of one section spigot-and-socket.Because sleeve pipe is welded to connect with the main body pipeline, thus during welding for doing the surface-treated pipeline, will damage the preservative coat on pipeline surface.Pot galvanize pipeline for example, in welding process, zinc coating will be destroyed.
For fear of the preservative coat damage of being responsible for, and then welding once more after avoiding the person in charge to finish dealing with, can adopt two sleeve pipes to connect.Existing pair of sleeve pipe connection form as shown in Figure 1, this kind connect to need three sleeve pipes, the i.e. first sleeve pipe 3a, the second sleeve pipe 4a, the 3rd sleeve pipe 6; Seven road soldereds, i.e. twice weld seam between the first sleeve pipe 3a and first steel pipe 1, the twice weld seam between the second sleeve pipe 4a and second steel pipe 2, the weld seam that the second sleeve pipe 4a and the 3rd sleeve pipe 6 connect, the weld seam that the first sleeve pipe 3a and the 3rd sleeve pipe 6 connect, the weld seam that the 3rd sleeve pipe 6 and bulkhead 5 connect.When pipeline passed bulkhead 5, the opening size on the bulkhead 5 was greater than the external diameter of the 3rd sleeve pipe 6, and the zinc coating of the 3rd sleeve pipe 6 can be destroyed when the welding of logical cabin.
The utility model content
The purpose of this utility model provides a kind of butt joint type double-bushing pipeline connecting structure, and it reduces weld seam, reduces logical cabin bore size, has improved the resistance to corrosion of sleeve pipe.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of butt joint type double-bushing pipeline connecting structure comprises first steel pipe, second steel pipe, first sleeve pipe, second sleeve pipe and bulkhead, and first casing pipe sleeve is on the outer wall of first steel pipe and second steel pipe, and first sleeve pipe and the welding of first steel pipe; Second casing pipe sleeve is on the outer wall of second steel pipe, and second sleeve pipe and second steel pipe, bulkhead weld respectively; First sleeve pipe and the welding of second sleeve pipe.
The beneficial effects of the utility model are: save sleeve pipe, reduce weld seam, reduce logical cabin bore size, improved the resistance to corrosion of sleeve pipe.
Description of drawings
Fig. 1 is existing double-bushing pipeline connecting structure scheme drawing.
Fig. 2 is a butt joint type double-bushing pipeline connecting structure scheme drawing of the present utility model.
Among the figure: 1, first steel pipe, 2, second steel pipe, 3, first sleeve pipe, 3a, first sleeve pipe, 4, second sleeve pipe, 4a, second sleeve pipe, 5, bulkhead, the 6, the 3rd sleeve pipe.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done description in further detail:
As shown in Figure 2, a kind of butt joint type double-bushing pipeline connecting structure of the present utility model comprises first steel pipe 1, second steel pipe 2, first sleeve pipe 3, second sleeve pipe 4 and bulkhead 5.
In actual mechanical process, carry out the blanking processing of steel pipe and sleeve pipe according to the size that drawing provides, and an end of two sleeve pipes processing bevel for welding; First sleeve pipe 3 is enclosed within on first steel pipe 1, and second sleeve pipe 4 is enclosed within on the outer wall of second steel pipe 2, finishes in the workshop and installs and welding, and the end that sleeve pipe has a groove and does not weld outwardly; The pipeline that machines carries out surface treatment or other processing.Go on board when installing, according to the installation site, perforate on bulkhead 5 in advance, second steel pipe 2 passes bulkhead 5 and inserts in first sleeve pipe 3, confirms errorless after, carry out the butt welding connection of two sleeve pipes; Carry out the welding of second sleeve pipe 4 and bulkhead 5 at last.
Will note in installation and the welding process measuring and guaranteeing following size: the distance H 1 between first steel pipe 1 and second steel pipe 2 is about 2mm～3mm; Gap H2 between sleeve pipe and the steel pipe is about 1mm～2mm; Distance H 3 between first sleeve pipe 3 and second sleeve pipe 4 is about 1mm.
As seen from Figure 2, pipeline connection of the present utility model only needs two sleeve pipes, i.e. first sleeve pipe 3 and second sleeve pipe 4; Four roads welding, i.e. weld seam between first sleeve pipe 3 and first steel pipe 1, the weld seam between second sleeve pipe 4 and second steel pipe 2, the weld seam that first sleeve pipe 3 and second sleeve pipe 4 connect, the weld seam of second sleeve pipe 4 and bulkhead 5 connections.Wherein, the weld seam that first sleeve pipe 3 and second sleeve pipe 4 connect, second sleeve pipe 4 need aboard ship be finished with the weld seam that bulkhead 5 connects, and when pipeline passed bulkhead 5, the opening size on the bulkhead 5 was greater than the external diameter of second sleeve pipe 4.Contrast as can be seen with Fig. 1; perforate on the bulkhead 5 can reduce the wall thickness (the perforate size reduces about 20mm) of a sleeve pipe, and when the welding of logical cabin, though the zinc coating of second sleeve pipe 4 damages; but, can not cause quick corrosion owing to there is the moisture film between second sleeve pipe 4 and second steel pipe 2 to protect.
Therefore, butt joint type double-bushing pipeline connecting structure of the present utility model has been saved the quantity of sleeve pipe, has reduced weld seam, reduced logical cabin bore size, when welding, though the zinc coating of sleeve pipe is destroyed with bulkhead, but sleeve pipe is the direct contact fluid not, and its resistance to corrosion improves.
