Abstract
The utility model discloses a flange pipe connecting structure of a steel container. The flange pipe connecting structure comprises a steel container (1) and a flange pipe (2), wherein the steel container (1) is provided with a connecting hole (11); the end part of the flange pipe (2) is inserted into the connecting hole (11); the edge of the outer side of the connecting hole (11) is provided with a groove (12); the inner side of the groove (12) is provided with a packing layer (3) formed by welding a J507RH welding rod through a half welding process; the outer side, which is close to the packing layer (3), of the groove (12) is provided with a normalizing pass (4); and the outer side of the normalizing pass (4) is provided with an arc-shaped recess (5). The flange pipe connecting structure has the advantages of small welding stress, high ductility and toughness, easiness and convenience in construction, and particular suitability for subsequent maintenance.
Description
Technical field
The utility model relates to carbon steel and low-alloy structural steel pressure field of containers, is specifically related to a kind of flanged pipe syndeton of steel vessel.
Background technology
The flanged pipe syndeton of steel vessel (for example 20g, 20R, 16Mug, 16MnR) generally also is called D class weld seam from Welding Structure.As shown in Figure 1, prior art D class weld seam comprises steel vessel 1 and flanged pipe 2, and steel vessel 1 is provided with connecting hole 11, and the end of flanged pipe 2 is inserted in connecting hole 11, and the outer ledge of connecting hole 11 is provided with groove 12, and groove 12 is provided with angle welding.The main feature of angle welding is: select the J507 welding rod; cross section is mutation status, and during welding, stress is very complicated, easily brings out delayed fracture in the process of weldering backing welding and weld bond operation; and J507 welding base metal intensity is because plasticity and toughness are poor, further the reliability of crisis steel vessel.
The utility model content
The technical problems to be solved in the utility model is to provide the flanged pipe syndeton of the steel vessel that a kind of welding stress is little, plasticity and toughness good, the construction is simple and convenient, be particularly useful for later period maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of flanged pipe syndeton of steel vessel, comprise steel vessel and flanged pipe, described steel vessel is provided with connecting hole, the end of described flanged pipe is inserted in described connecting hole, and the outer ledge of described connecting hole is provided with groove, the inboard of described groove is provided with the packed layer that adopts half road Welding welding to form by the J507RH welding rod, and described groove leans on the outside of packed layer to be provided with normalizing pass.
As further improvement in the technical proposal:
The outside of described normalizing pass is provided with the arc recess.
The utlity model has following advantage:
1, the inboard of the utility model groove is provided with the packed layer that adopts half road Welding welding to form by the J507RH welding rod, and groove is provided with normalizing pass by the outside of packed layer, can reduce structural stress by compound structure, be not easy to bring out delayed fracture in the process of weldering backing welding and weld bond operation, have that welding stress is little, plasticity and toughness good, the advantage simply and easily of constructing, be particularly useful for the later stage to the maintenance of the flanged pipe syndeton of steel vessel.
2, the outside of normalizing pass of the present utility model further is provided with the arc recess, can further reduce stress, is not easy to bring out delayed fracture.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the sectional structure schematic diagram of prior art.
Fig. 2 is the sectional structure schematic diagram of the utility model embodiment.
Marginal data: 1, steel vessel; 11, connecting hole; 12, groove; 2, flanged pipe; 3, packed layer; 4, normalizing pass; 5, arc recess.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made more explicit defining.
As shown in Figure 2, the flanged pipe syndeton of the steel vessel of the present embodiment comprises steel vessel 1 and flanged pipe 2, steel vessel 1 is provided with connecting hole 11, the end of flanged pipe 2 is inserted in connecting hole 11, and the outer ledge of connecting hole 11 is provided with groove 12, the inboard of groove 12 is provided with the packed layer 3 that adopts half road Welding welding to form by the J507RH welding rod, and groove 12 leans on the outside of packed layer 3 to be provided with normalizing pass 4.The present embodiment can reduce structural stress by compound structure, be not easy to bring out delayed fracture in the process of weldering backing welding and weld bond operation, have that welding stress is little, plasticity and toughness good, the advantage simply and easily of constructing, be particularly useful for the later stage to the maintenance of the flanged pipe syndeton of steel vessel.The J507RH welding rod that uses in the present embodiment is high tenacity, ultralow hydrogen type electrode, and diameter is 2.5～3.2mm, can guarantee to have certain plasticity, toughness under the prerequisite of structure, supplies in the situation that certain stress provides sufficient plasticity, toughness deposit.
In the present embodiment, the outside of normalizing pass 4 is provided with arc recess 5, can further reduce stress, is not easy to bring out delayed fracture.
Take to the maintenance of the flanged pipe syndeton of steel vessel as example, after the end of flanged pipe 2 was inserted in connecting hole 11, the process of the present embodiment was as follows:
1) adopting diameter is that the J507RH welding rod of 2.5～3.2mm applies one decks at groove 12 surface heaps;
2) before weldering packed layer 3, with last layer surface finish, touch the pit on surface, make it be a plane.
3) use the J507RH welding rod of 3.2mm, the packed layer 3 that adopts half road Welding welding to form during extremely surface to be welded, adds weldering normalizing pass 4;
4) treat that nondestructive inspection or the water pressure test are qualified after, normalizing pass 4 polishing is formed arc recess 5;
5) heat treatment of postwelding, but when reprocessing the degree of depth less than removing the heat treatment of postwelding from three of steel vessel 1 steel plate thickness/a period of time.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvements and modifications of carrying out under the prerequisite that does not break away from principle of the present utility model, these improvements and modifications also should be considered as protection domain of the present utility model.
