Abstract
The invention relates to a welding neck flange. The welding neck flange comprises a flange body, and the flange body comprises a disc part (1), a first connecting part (3) and a second connecting part (4). The disc part (1) is arranged in the middle of the flange body, the first connecting part (3) is arranged on the upper portion of the flange body, and the second connecting part (4) is arranged on the lower portion of the flange body. Multiple installation holes (2) are formed circumferentially in the disc part (1), and a pipeline hole (5) is formed in the center of the flange body. The welding neck flange is characterized in that a first inclined section (3.1), a straight section (3.2) and a second inclined section (3.3) are sequentially arranged on the outer wall of the first connecting part (3) from top to bottom, the outer wall of the second connecting part (4) is a straight line section, the flange body is made of titanium steel, and a nickel-plated layer is arranged on the outer surface of the flange body. Due to the special structural design, the welding neck flange has the advantage of being high in strength.
Description
Technical field
The present invention relates to a kind of flange, particularly relate to a kind of welding neckflange, belong to pipe fitting technical field.
Background technique
Flange is again flange plate or bead.Flange makes pipe and the interconnective part of pipe, is connected to pipe end.Perforation on flange, bolt makes two flanges be close to.Liner containment is used between flange.
Tradition pipe fitting connection time be adopted as welding type, because strength of flange is lower, during welding produce distortion, pipe fitting is leaked, therefore seeks the higher welding neckflange of a kind of intensity particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the welding neckflange that a kind of intensity is higher is provided.
The object of the present invention is achieved like this:
A kind of welding neckflange, it comprises flange body, round plate in the middle part of described flange body comprises, first joint on top and the second joint of bottom, on described round plate, hoop is provided with multiple mounting hole, the center of described flange body offers pipe hole, the outer wall of described first joint comprises the first oblique section, straight section and the second oblique section from top to bottom successively, the outer wall of described second joint is straightway, described flange body is made up of titanium steel material, and the outer surface of described flange body is provided with nickeling layer.
Preferred as one, the slope of the described first oblique section is less than the slope of the second oblique section, and the height of the described second oblique section accounts for 60 ~ 70% of the first joint height.
Compared with prior art, the invention has the beneficial effects as follows:
The structural design that the present invention is special, makes this welding neckflange have the higher advantage of intensity, not easily producing distortion, avoiding pipe fitting to leak when welding, and improves working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of welding neckflange of the present invention.
Wherein:
Round plate 1
Mounting hole 2
The oblique section 3.1 of first joint 3, first, the oblique section 3.3 of straight section 3.2, second
Second joint 4
Pipe hole 5.
Embodiment
