Abstract
The invention relates to a jacket flange manufacturing technics. The technics comprises the manufacturing, assembly, welding, refined adding and water pressure test of a baiting, a flange and a flange jacket. During the assembly procedure, proceed welding a divided edge at the out edge at the connection surface of the flange and the flange jacket, the angle of the divided edge Alfa is 35 to 55 degree, the thickness of the root face of the divided edge mustn't exceed 1mm; during welding procedure, adopt argon arc welding priming and manual arc welding facing. With the controlling to the technics index of the angle of the divided edge and the thickness of the root face of the divided edge and the welding method, the invention ensures the welding being able of through, ensures the welding quality of the welding line, overcomes the defect of the position of the flange and the flange jacket is easy to leak, and prolongs the service life of the product.
Description
Technical field
The present invention relates to a kind of manufacture technique of jacket flange.
Background technology
The manufacture craft such as roll of the forging of flange, chuck is ripe, and key is for the attachment weld of guaranteeing flange and chuck is not in use revealed, in manufacture process, just must take into full account the slope type and the welding method of weld seam.And, when flange roughing and chuck blanking, should take into full account accurately machined surplus.If just simple performance requirement and the physical dimension requirement of considering product, with the attachment weld that causes flange and chuck probably after fine finishining, the thickness deficiency of the fused portion of its weld seam.On the other hand, at present, a lot of manufacturers are thought, add the pressure that overlap interior media not high (0.1MPa), when welding, can square groove or angle of preparation is too small, root face is too thick, or all adopt the method for manual spot arc welding to weld.Butt welded seam does not detect yet, and does not carry out the water pressure test yet.Like this, cause product after machine-shaping, the fused portion of weld seam is too thin, or there is pore in weld seam, defective such as is mingled with.Make product in use the dielectric fluid in the chuck leak or shorten service life of product.
Summary of the invention
Easily cause weld seam to have pore, defective such as be mingled with in order to overcome common manufacture technique of jacket flange, product in use flange and flange chuck place easily produces the deficiency of leakage, the invention provides a kind of manufacture technique of jacket flange.
The technical solution adopted for the present invention to solve the technical problems is: a kind of manufacture technique of jacket flange, technical process comprises that the manufacturing, group of blanking, flange and flange chuck are to, welding, fine finishining and the water pressure test, in organizing to operation, outer rim Vehicle Processing bevel for welding at the faying face place of flange and flange chuck, the angle [alpha] of groove is 35 °～55 °, the root face height H of groove must not surpass 1mm, can guarantee through welding; In welding sequence, adopt inferior arc-welding bottoming, manual electric arc welding capping.
The present invention passes through the technological parameter of the root face height of bevel angle, groove and the control of welding method, guaranteed that welding can through welding, the welding quality of assurance weld seam has overcome flange and flange chuck place easily produces the deficiency of leakage, has prolonged the service life of product.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the jacket flange structural representation.
Fig. 2 is the partial sectional view of Fig. 1.
Among the figure: 1. chuck 2. jacket flanges 3. inferior arc-welding 4. manual electric arc weldings
The specific embodiment
A kind of manufacture technique of jacket flange, technical process comprise that the manufacturing, group of blanking, flange and flange chuck are to, welding, fine finishining and the water pressure test.As shown in Figure 1 and Figure 2, in organizing operation, at the outer rim Vehicle Processing bevel for welding of flange 1 with the faying face place of flange chuck 2, the angle [alpha] of groove is 35 °～55 °, and the root face height H of groove must not surpass 1mm; In welding sequence, adopt inferior arc-welding bottoming, manual electric arc welding capping.
Claims (1)
1. manufacture technique of jacket flange, technical process comprises that the manufacturing, group of blanking, flange and flange chuck are to, welding, fine finishining and the water pressure test, it is characterized in that: in organizing operation, outer rim Vehicle Processing bevel for welding at the faying face place of flange and flange chuck, the angle [alpha] of groove is 35 °～55 °, and the root face height H of groove must not surpass 1mm; In welding sequence, adopt inferior arc-welding bottoming, manual electric arc welding capping.
