Abstract
A testing device for intercrystalline corrosion of nickel-base alloy N10675in pressure hydrochloric acid method is characterized by comprising a zirconium bottom plate (1), a zirconium container wall (2), a lining zirconium steel flange cover (3), a steel loose flange (4) and a zirconium temperature measuring sleeve pipe (7) used for mounting a temperature pipe. The lower portion of the zirconium container wall (2) is connected with the zirconium bottom plate (1) in integral welded mode. The upper portion of the zirconium container wall (2) is provided with a zirconium container wall edge (5) extending outwards. One side of the lining zirconium steel flange cover (3) with a lining zirconium (6) contacts with the zirconium container wall edge (5). The steel loose flange (4) is arranged on the zirconium container wall (2) in sleeved mode and is connected with the lining zirconium steel flange cover (3) through connecting bolts. The zirconium temperature measuring sleeve pipe (7) penetrates through the lining zirconium steel flange cover (3) and extends into an experiment container composed of the zirconium bottom plate (1) and the zirconium container wall (2). The zirconium temperature measuring sleeve pipe (7) is connected with the lining zirconium (6) in welding mode. A heating device is arranged on an outer side of the zirconium container wall (2). The testing device is simple in structure, convenient to manufacture, good in corrosion resistance and sealing of testing intermediate, and totally meets requirements of the experiments.
Description
Technical field
The utility model relates to a kind of test unit, especially a kind of material Huey test device, specifically a kind of nickel-base alloy N10675 pressurization salt acid system Huey test device.
Background technology
Nickel-base alloy N10675 is a kind of important resistant material, is widely used in the device fabrication of chemical products productions such as acetic acid, aceticanhydride and formic acid.For test material supplier or equipment manufacturing because the tendency of the improper N10675 material generation intercrystalline corrosion that causes of thermal treatment need adopt special test unit and tested media that material is carried out the detection of intercrystalline corrosion tendency in testing laboratory.Require material sample to be immersed in the hydrochloric acid that tested media is a concentration 20% during experiment, and under the airtight condition of 149 ℃ of temperature, be incubated 96 hours.Because the hydrochloric acid of concentration 20% has severe corrosive under 149 ℃, the container of therefore testing the splendid attire tested media of usefulness is the key of test unit, should the long corrosion of anti-tested media have good leakproofness again.The current experiments device all is to adopt steel vessel, and PTFE is as liner, because PTFE is a kind of organic material, the bonding properties of itself and steel is relatively poor, so the moulding difficulty is big, and airtight performance is difficult to satisfy testing requirements, is necessary to improve.
Summary of the invention
The purpose of the utility model is that to shape difficulty to existing nickel-base alloy N10675 Huey test container big; The problem that leakproofness is relatively poor designs a kind of nickel-base alloy N10675 pressurization salt acid system Huey test device that utilizes the resistant material zirconium to make.
The technical scheme of the utility model is:
A kind of nickel-base alloy N10675 pressurization salt acid system Huey test device; It is characterized in that it comprises zirconium base plate 1, zirconium chamber wall 2, lining zirconium steel blind flange 3, steel lap joint flange 4 and is used to install the zirconium temperature-measuring casing 7 of temperature tube; The bottom of described zirconium chamber wall 2 links to each other with zirconium base plate 1 integral solder; The top of zirconium chamber wall 2 is provided with the zirconium chamber wall limit 5 of outside extension; The one side that serves as a contrast zirconium 6 that has of lining zirconium steel blind flange 3 contacts with zirconium chamber wall limit 5, and steel lap joint flange 4 is sleeved on the zirconium chamber wall 2 and through coupling bolt and links to each other with lining zirconium steel blind flange 3, and described zirconium temperature-measuring casing 7 passes lining zirconium steel blind flange 3 and stretches in the test chamber of being made up of zirconium base plate 1 and zirconium chamber wall 2; Described zirconium temperature-measuring casing 7 is weldingly connected with lining zirconium 6, and the outside of zirconium chamber wall 2 is equipped with heating arrangement.
Between described lining zirconium 6 and the zirconium chamber wall limit 5 sealing gasket is installed.
The beneficial effect of the utility model:
The utility model is simple in structure, and is easily manufactured, and corrosion of ability tested media and good leak tightness can satisfy testing requirements fully.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1.
A kind of nickel-base alloy N10675 pressurization salt acid system Huey test device; It comprises zirconium base plate 1, zirconium chamber wall 2, lining zirconium steel blind flange 3, steel lap joint flange 4 and is used to install the zirconium temperature-measuring casing 7 of temperature tube; The bottom of described zirconium chamber wall 2 links to each other with zirconium base plate 1 integral solder; The top of zirconium chamber wall 2 is provided with the zirconium chamber wall limit 5 of outside extension; The one side that serves as a contrast zirconium 6 that has of lining zirconium steel blind flange 3 contacts with zirconium chamber wall limit 5, and steel lap joint flange 4 is sleeved on the zirconium chamber wall 2 and through coupling bolt and links to each other with lining zirconium steel blind flange 3, and described zirconium temperature-measuring casing 7 passes lining zirconium steel blind flange 3 and stretches in the test chamber of being made up of zirconium base plate 1 and zirconium chamber wall 2; Described zirconium temperature-measuring casing 7 is weldingly connected with lining zirconium 6, and the outside of zirconium chamber wall 2 is equipped with heating arrangement.In order to improve sealing property, also can between lining zirconium 6 and zirconium chamber wall limit 5, sealing gasket (can adopt the PTFE manufacturing) be installed during practical implementation, sealing gasket also can adopt mechanical seal structure to realize.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
