Description
Technical field
This utility model relates to the assessment technique of the corrosion inhibition of high-temperature corrosion inhibitor, specifically a kind of high temperature corrosion lacing film
Retort.
Background technology
At present, when checking sewage water corrosion inhibitor, in order to investigate the corrosion inhibition of corrosion inhibiter, main employing static corrosion hanging slice method
Test.For the corrosion inhibiter that oil field is currently used, according to stratum recovered water and in-situ processing requirement, it is usually at 50 DEG C
Under carry out lacing film, use glass jar to be linked into test piece, then by rubber stopper seal, adhesive tape is fixed, then at 50 DEG C
After constant temperature is placed 7 days, the mass loss of lacing film after measuring blank respectively and adding corrosion inhibiter.At present oil field inhibition
Agent mostly is room temperature corrosion inhibiter, uses temperature less than 60 DEG C.But individual fields multi-purpose station sewage disposal temperature is exceeded
80 DEG C, for the evaluation of high-temperature corrosion inhibitor corrosion inhibition, the method still using wide mouthed bottle rubber stopper seal, along with reaction
The prolongation of time, then there will be that rubber stopper deformation is prominent, in wide mouthed bottle corrosion in water medium reduce, lacing film mass loss not
Parallel phenomenon.Therefore temperature being higher than to the static corrosion hanging test of 80 DEG C, the airtight lacing film needing design specialized is anti-
Answer device.
Utility model content
The purpose of this utility model is to provide a kind of high temperature corrosion lacing film retort, can evaluation temperature be higher than more accurately
The performance of the high-temperature corrosion inhibitor corrosion inhibition in the static corrosion coupon test of 80 DEG C.
In order to reach above-mentioned purpose, this utility model have employed following technical scheme, a kind of high temperature corrosion lacing film retort,
Including tank body and the sealing lid that is arranged on tank body upper port, described close closure base portion offers lacing film hole, and described tank body is built-in
Entering to simulate water, hang up test piece on lacing film hole, test piece simultaneously invades in simulation water, and the described lid that seals is opened the most successively
If the sealing valve opening being connected, steam vent.
Described inner tank wall is provided with polytetrafluoroethyllining lining, and this liner inwall arranges 894 milliliters of liquid level lines, 1 liter of liquid level
Line.
Described lacing film hole arranges three, divides equally setting for 120 ° ringwise.
Described inner tank wall is offered for shelving the interior land sealing lid.
Described sealing arranges sealing ring between lid and tank body.
Described tank body upper end is offered radial hole and interfixes with sealing lid with sealing holding screw.
Described tank body is stainless steel tank body, seals lid and seals lid for rustless steel.
Compared to prior art, this utility model has the advantages that
This utility model can more accurately evaluation temperature higher than the high-temperature corrosion inhibitor in the static corrosion coupon test of 80 DEG C
Corrosion inhibition.

Put the interior land sealing lid.Described sealing arranges sealing ring 8 between lid and tank body.Described tank body upper end is offered radial hole and uses
Seal holding screw 7 and interfix with sealing lid.Described tank body is stainless steel tank body 1, seals lid and seals lid 3 for rustless steel.
1, polytetrafluoroethyllining lining is loaded in stainless steel tank body, require to load certain volume according to corrosion inhibiter examination criteria
On-the-spot recovered water or artificial preparation simulation water.
2,3 test pieces handled well are hung on 120 ° respectively and divide equally lacing film hole, and load in tank body.
3, check seal cap sealing circle, load and seal valve opening, cover tightly sealing lid, with spanner, sealing bolt is carried out tightening.
4, high temperature static corrosion coupon test retort being put into calorstat, constant temperature places an examination at a set temperature
Test the cycle.
5, after off-test, retort is taken out in calorstat, place to room temperature, first unclamp sealed valve stem release
Pressure, then unclamps sealing bolt, is taken out by lacing film, cleans and process, observe and record corrosion condition.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other
Use the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
