Description
Technical field
This utility model relates to a kind of nickel pipe abutted flange structure, particularly a kind of carbon steel lining nickel strap neck W.N flange.
Background technology
At present, carry high temperature in the production industry such as chemical industry, medicine, the nickel pipe of high pressure matter Jie utilizes lining when docking in termination
Ring docking structure, although it is cheap, but in use, owing to connecting the moment of torsion that the cold and hot change of pipeline causes, easily at lining
The sealing surface of ring and the right angle Kou Chu of pipe crack, and once produce leakage, it is more likely that cause the injures and deaths of personnel and production to set
Standby damage, also exists serious potential safety hazard.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in construction, easy to operate, intensity is high, be hardly damaged, safe and reliable
Carbon steel lining nickel strap neck W.N flange, overcome the deficiencies in the prior art.
Carbon steel of the present utility model lining nickel strap neck W.N flange, including the first nickel pipe being mutually butted and the second nickel pipe,
It is set with the first flange on the termination of the first nickel pipe, between a side periphery and the outer surface of the first nickel pipe of the first flange, has
One nickel overlay cladding, on the opposite side end face of the first flange, heap is welded with second overlay cladding in face, protruding end；End at the second nickel pipe
It is set with the second flange on Tou, between a side periphery and the outer surface of the second nickel pipe of the second flange, has the 3rd nickel overlay cladding,
On the opposite side end face of the second flange, heap is welded with the 4th recessed overlay cladding；First flange is radially provided with the first ventilation
Hole, is radially provided with the second passage on the second flange；It is provided with sealing between the docking termination of the first nickel pipe and the second nickel pipe
Pad.
Carbon steel of the present utility model lining nickel strap neck W.N flange, after installation, flange sealing surface is nickel overlay cladding, with carbon steel material
The ring flange body of material is combined closely, and enhances the bonding strength of sealing surface and nickel pipe；Nickel pipe welds with neck flange end, it is to avoid
The safety causing pipeline to be revealed because the cold and hot deformation of nickel pipe causes the right angle mouth of sealing surface and pipe to crack in prior art
Hidden danger, has simple in construction, easy to operate, intensity is high, be hardly damaged, safe and reliable advantage.
Accompanying drawing explanation
The structural representation of Fig. 1 this utility model detailed description of the invention；
Fig. 2 is the first nickel pipe shown in Fig. 1 and the structural representation of the first flange；
Fig. 3 is the second nickel pipe and the structural representation of the second flange of Fig. 1 institute method.
Detailed description of the invention
As shown in Figure 1, 2, 3: this utility model includes the first nickel pipe 1 and the second nickel pipe 11 being mutually butted.At the first nickel
It is set with the first flange 3 on the termination of pipe 1, between a side periphery and the outer surface of the first nickel pipe 1 of the first flange 3, has first
Nickel overlay cladding 2, on the opposite side end face of the first flange 3, heap is welded with second overlay cladding 5 in face, protruding end；
The termination of the second nickel pipe 11 is set with the second flange 9, at a side periphery and the second nickel pipe 11 of the second flange 9
Outer surface between have the 3rd nickel overlay cladding 10, on the opposite side end face of the second flange 9, heap is welded with the 4th recessed overlay cladding
7；
First flange 3 is radially provided with the first passage 4, the second flange 9 is radially provided with the second passage 8；
It is provided with sealing gasket 6 between the first nickel pipe 1 and the docking termination of the second nickel pipe 11.
After installation, flange sealing surface is nickel overlay cladding, combines closely with the ring flange body of carbon steel material, enhances sealing
Face and the bonding strength of nickel pipe；Nickel pipe welds with neck flange end, it is to avoid cause close because of nickel pipe cold and hot deformation in prior art
The potential safety hazard that the right angle mouth of front cover and pipe cracks and causes pipeline to be revealed, has simple in construction, easy to operate, intensity
High, be hardly damaged, safe and reliable advantage.
