Abstract
The utility model discloses a kind of alloy welded pipe, including the first adapter, the second adapter and connecting tube, first adapter and the second upper position close to the mouth of pipe of adapter are equipped with annular protrusion, the raised outer wall is arcwall face, the two ends of the connecting tube are provided with groove, and the outer wall of groove is arcwall face, the two ends of connecting tube distinguish grafting first take over, the second adapter, projection contacts and welded with cut.The utility model is simple in construction, reasonable in design, and bonding area is big, and firm welding is difficult leakage, and weld seam is smoothly attractive in appearance, continuous strength is high, it is to avoid stress concentration, improves the tensile strength of position while welding.
Description
Technical field
The utility model belongs to connecting tube technical field, more particularly to a kind of alloy welded pipe.
Background technology
The welded pipe of prior art is typically all that many piece-root grafting pipes are directly welded, and it has the disadvantage that, solder side
Product is small, insecure, is easily revealed in commissure, and weld seam is unsmooth attractive in appearance, commissure stress concentration, therefore tension is strong
Degree is low.
Therefore, how to solve above-mentioned technical problem becomes the direction of art personnel effort.
Utility model content
The purpose of this utility model is just to provide a kind of alloy welded pipe, can be fully solved above-mentioned the deficiencies in the prior art it
Place.
The purpose of this utility model is realized by following technical proposals：
In a kind of alloy welded pipe, including the first adapter, the second adapter and connecting tube, first adapter and the second adapter
Position close to the mouth of pipe is equipped with annular protrusion, and the raised outer wall is arcwall face, and the two ends of the connecting tube are provided with groove, and
The outer wall of groove is arcwall face, the two ends of connecting tube distinguish grafting first take over, the second adapter, projection contacts and carries out with cut
Welding.
Further, first adapter, the second adapter, connecting tube and face of weld are coated with high-temperature resistant anti-corrosive coating.
Further, high-temperature resistant anti-corrosive coating is coated in the range of the weld seam both sides 5cm.
Further, first adapter and the second adapter surface are electroplate with nickel dam.
Compared with prior art, the beneficial effects of the utility model are：Simple in construction, reasonable in design, bonding area is big,
Firm welding is difficult leakage, and weld seam is smoothly attractive in appearance, continuous strength is high, it is to avoid stress concentration, improves the tension of position while welding
Intensity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described with reference to specific embodiments and the drawings.
As shown in figure 1, a kind of alloy welded pipe, including the first adapter 1, the second adapter 2 and connecting tube 3, described first connects
Position in the adapter 2 of pipe 1 and second close to the mouth of pipe is equipped with annular protrusion 4, and the outer wall of the projection 4 is arcwall face, the connection
The two ends of pipe 3 are provided with groove 5, and the outer wall of groove 5 is arcwall face, two ends the first adapter of difference grafting 1, second of connecting tube 3
Adapter 2, projection 4 is contacted and welded with cut 5.The outer wall of cut 5 is the arcwall face of indent either evagination.The company
The two ends of adapter 3 are the insertion depth of stepped hole, the first adapter 1 of convenient positioning and the second adapter 2.
The face of weld is coated with high-temperature resistant anti-corrosive coating（It is not drawn into figure）, and in the range of the 5cm of weld seam both sides
High-temperature resistant anti-corrosive coating is also coated with one adapter 1, the second adapter 2 and connecting tube 3.High-temperature resistant anti-corrosive coating can be realized reliably
Dissimilar material joining, i.e. when the first adapter 1, the second adapter 2 are different from the material of connecting tube 3, dissimilar metal can be avoided to connect
The corrosion problems that the potential difference of generation is brought.
The electroplating surface of first adapter, 1 and second adapter 2 has nickel dam.
During welding, projection 4 is welded with groove 5, and as temperature is raised, both mutually fuse into one, and weld seam is smoothly attractive in appearance,
There is no straight flange transition, it is to avoid stress concentration, improve the tensile strength of posetionof weld.Also, bonding area is big, firm welding
It is difficult leakage.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
