Description
Technical field
The utility model is related to a kind of Special test container, more particularly to a kind of to be used for pipe line steel hydrogen sulfide hydrogen induced cracking (HIC)
Corrosion test container.
Background technology
(English full name is pipe line steel anti-H 2 S hydrogen induced cracking (HIC) HIC:Hydrogen induced cracking) experiment be
Important detection project.Many test details are defined in hydrogen induced cracking (HIC) HIC experiment international standards.Mainly include in process of the test
Solution isolating oxygen, sample solution are than, concentration of hydrogen sulfide of testing liquid etc..Stop-leak compound is smeared using glassware mouthful, adds close
The measures such as sealing rubber ring improve container air-tightness and there is respective shortcoming.After container volume is increased, single examination can be dramatically increased
Test the concentration of hydrogen sulfide dissolved in ability, but testing liquid and be not readily reachable by saturation, finally make test failure.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of process of the test can be under the conditions of big liquor capacity
Hydrogen induced cracking (HIC) testing standard is improved, and further improves the air-tightness of test chamber to improve the hydrogen induced cracking (HIC) of operating efficiency
Corrosion test container.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of hydrogen induced cracking (HIC) HIC experiments are held
Device, including vessel, the lid for being arranged on body upper part, the vessel inner chamber are provided with dividing plate, and described the lower partition is set
There is a bubbler, the bubbler is provided with triple valve, be connected by pipeline and the vessel inwall and extend the appearance
Device body exterior connects gas handling system.
The bubbler is circular rings, and ring body is provided with downwardly open stomata.
Seal washer is provided with the lid, the lid is provided with gas outlet.
The dividing plate is provided with the hole of rule distribution and provided with multilayer.
The vessel bottom is provided with bleeder valve.
The beneficial effects of the utility model are：Bubbler shorten hydrogen sulfide dissolve in testing liquid reach needed for saturation when
Between, therefore significantly improve test efficiency；Test chamber is simple in construction, with low cost, implements easy, easy to use.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, a kind of hydrogen induced cracking (HIC) HIC test chambers, volume is up to 80L, including vessel 1, is arranged on this
The lid on the top of body 1, the inner chamber of vessel 1 is provided with dividing plate 3, and the bottom of dividing plate 3 is provided with bubbler 4, and bubbler 4 is provided with triple valve 8,
It is connected and extends outside the vessel 1 by pipeline and the inwall of vessel 1.Bubbler 4 adds gas
With the contact area of testing liquid, the agitation of solution in process of the test is added, is conducive to the homogeneous of testing liquid environment.
As shown in Figure 2 and Figure 3, the connection of bubbler 4 air inlet, bubbler 4 is circular rings, and ring body is provided with downwardly open gas
Multiple gas outlet designs on hole 9,10,11,12, bubbler, add gas handling system positioned at container the latter half, significantly shortening to make
In big liquor capacity hydrogen sulfide gas saturation need to time, improve the uniformity of solution environmental in whole test chamber, to
Under opening prevent the blocking of corrosion product.Vessel port installs the silica gel plate pad of hydrogen sulfide corrosion-resistant, bolt fit sealing, increase additional
The air-tightness of container.Cover provided with gas outlet 7, slow down the pressure of interior.Dividing plate 3 is provided with multilayer, can once place multiple
Sample, improves single test ability, and every layer of hole provided with rule distribution is easy to sample solution to flow.The bottom of vessel 1
Provided with bleeder valve 5, brake wheel 6 is arranged at bottom, is moved easily.
The course of work of the container is as follows：
Bubbler 4 is connected with container case body sidewall air inlet, dividing plate 3 is placed in container, sample is placed on dividing plate, is held
Sealing gasket 2 and fastening bolt are put between device lid and box mouth.Air inlet, gas outlet 7 are connected, is removed with high pure nitrogen through bubbler 4
Air in casing.Import the testing liquid through pre- deoxygenation.Hydrogen sulfide gas is introduced to examination through stomata 9.10.11.12 on bubbler 4
Test in solution.Experiment is removed in solution after hydrogen sulfide before terminating with high pure nitrogen, takes out sample.
The utility model test chamber, gas handling system is located at container the latter half, is designed with special bubbler, adds gas
The contact area of body and testing liquid, adds the agitation of solution in process of the test, is conducive to the homogeneous of testing liquid environment.Root
According to sample quantities, flexible arrangement is equipped with the quantity of dividing plate.The roller with brake apparatus is installed in container bottom, can easily be moved
Dynamic test container.The brake apparatus on roller is opened, test chamber can be moved in experiment cabinet by operating personnel, relock roller
Remain stationary as abrasive machine, call through test gas.
