Abstract
The utility model relates to a welding structure of a heat exchanging tube and a tube plate, which comprises a heat exchanging tube and a tube plate, and is characterized in that the end part of the heat exchanging tube is inserted inside the middle part of a tube hole of the tube plate, and a weld bead is arranged on the end part of the heat exchanging tube inside the tube hole of the tube plate.The welding structure has the advantages that the vertical positioning of the heat exchanging tube and the tube plate is easy and is free from being deviated, the processing is simple and convenient,the quality is easy to be ensured, the connection strength is good, and the tightness and the pull-off prevention capacity at the connection position also can be ensured under high temperature and high pressure.
Description
Technical field
The utility model belongs to a kind of Welding Structure of heat exchanger tube and tube sheet of heat exchanger.
Background technology
The heat exchanger tube in the existing heat exchanger and the Welding Structure of tube sheet, have following three kinds: a kind of is that the end of heat exchanger tube is with after the pore of tube sheet contacts, welding gun gos deep into welding in the pore of tube sheet, its structure is superior, but its performance difficulty, simultaneously, deviation takes place in the perpendicular positioning of heat exchanger tube and tube sheet easily, and crudy is affected.Second kind: the method for attachment of adopting expanded joint that is connected of heat exchanger tube and tube sheet, between tube-to-tube sheet connection, be provided with O-ring seal, its shortcoming is that operation easier is bigger, production efficiency is lower.The third: heat exchanger tube adopted the tube-to-tube sheet connection expanded and welded tube joint and uses method with being connected of tube sheet, and its shortcoming is the technology more complicated, and production efficiency is lower.
The utility model content
The purpose of this utility model provides the Welding Structure of a kind of heat exchanger tube and tube sheet, and the perpendicular positioning of heat exchanger tube and tube sheet is easy, processes easyly, easily ensures the quality of products, and bonding strength is good, can guarantee also that when HTHP the compactness of junction and tension take off ability.
The purpose of this utility model is achieved by the following technical solution: it comprises heat exchanger tube, tube sheet, it is characterized in that: the end of heat exchanger tube is inserted in the middle part of tube sheet pore, and its welding bead is positioned at the heat exchanger tube end of tube sheet pore.
The utility model has the advantages that: deviation easily, does not take place in the perpendicular positioning of heat exchanger tube and tube sheet, process easy, easily ensure the quality of products, bonding strength is good, can guarantee also that when HTHP the compactness of junction and tension take off ability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See Fig. 1, concrete structure of the present utility model is as follows: during welding, earlier the end of heat exchanger tube 1 is inserted in the medium position 3 of tube sheet 2 pores, forms perpendicular positioning.Then, welding gun welds from the end that the tube sheet pore extend into heat exchanger tube 1.Heat exchanger tube end in the tube sheet pore forms welding bead.Realize that the plumb joint high-quality connects, satisfy 100% radiographic inspection requirement, guarantee the safe operation of equipment effectively.
