Abstract
The utility model discloses a hanging piece rack for an autoclave corrosion test. The hanging piece rack comprises a clamp and a fixing bolt, wherein the clamp consists of an upper-end disc (1), two middle discs (4) used for embedding samples, and a lower-end disc (6); a fixing hole is formed in the clamp so that the clamp can be linked with an autoclave stirring shaft; a bolt hole is formed in the periphery of the clamp so as to contain the fixing bolt. During the test, different samples can be tested, the samples have the same height and are difficult to drop, and the sample corrosion test is smoothly performed. In addition, the clamp in the hanging piece rack is made of an inorganic insulating material, a galvanic couple effect is avoided, the hanging piece rack has excellent temperature resistance and corrosion resistance, and the test error is reduced. The hanging piece rack can be used for simulating corrosion performance tests of materials under various oil and gas field environmental conditions.
Description
Technical field
The utility model relates to a kind of test unit, is specifically related to a kind of autoclave corrosion test sample film hangers.
Background technology
Corrosion is oil and natural gas problem demanding prompt solution always, and present domestic conventional autoclave is mainly used in the corrosive nature of evaluating material under static state or dynamic action under high temperature, high pressure, and then studies the mechanism of corrosion and formulate corresponding anticorrosion strategy.The corrosive nature of evaluating material mainly adopts hanging slice method, and specimen shape is simple sheet rectangular parallelepiped.Autoclave hanging slice method is divided into again static high pressure pot hanging slice method and dynamic high-pressure still hanging slice method.In static high pressure pot corrosion test, sample is just fixed on film hangers, and is not rotated; In dynamic high-pressure still corrosion test, sample need to be along with the rotation axis rotation of autoclave.
Utility model content
The purpose of this utility model is to provide a kind of Static and dynamic film hangers that all spendable autoclave corrosion test is used, and can effectively avoid sample to come off at the trial, makes film hangers assembling and easy to process simultaneously.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of autoclave corrosion test film hangers, described film hangers comprises fixture and fixing pin, it is characterized in that: described fixture is comprised of for embedding intermediate disc, the lower end disk of sample two of upper end disc ﹑, on described fixture, offer fixed orifice to link with autoclave shaft, on the periphery of described fixture, also offer tip hole to hold described fixing pin.
Wherein, at two of the centres of described fixture disk, also offer identical, the regularly arranged a plurality of holes of size.
Wherein, fixture is vertical with fixing pin, and two of described upper end disc ﹑ embed between the intermediate disc of sample, lower end disc parallel to each other.Described film hangers is connected with the shaft of autoclave.Fixture is made by inorganic insulating material.
Of the present utility model have a following beneficial effect:
1) autoclave film hangers of the present utility model at the trial sample be tightly clipped between disk, and sample is vertical, in dynamic corrosion test, sample is not easy to come off, and is conducive to more successfully carry out sample corrosion test;
2) autoclave film hangers of the present utility model can carry out at most the test of a plurality of as 9 samples simultaneously, can carry out lacing film according to the quantity of the required sample of test, has greatly improved work efficiency;
3) at the trial, all samples are in sustained height to autoclave film hangers of the present utility model, have reduced experimental error;
4) autoclave film hangers of the present utility model is simple in structure, and the installation and removal of sample are very convenient;
5) when the fixture of autoclave film hangers of the present utility model is made, adopt inorganic high borosilicate material, easily processing, can not produce bimetallic corrosion, has good heatproof and corrosion resistance, has reduced test error;
6) when the fixing pin of autoclave film hangers of the present utility model and supporting nut are made, adopt stainless steel material, do not contact with sample, there is good heatproof and corrosion resistance, reduced test error;
7) autoclave film hangers of the present utility model can be done static corrosion test in autoclave the inside and also can do dynamic corrosion test;
8) autoclave film hangers of the present utility model can be applied in the simulation test under the various corrosion environments of oil gas field, and applicable test temperature is up to 350 ℃.
Accompanying drawing explanation
Fig. 1～Fig. 3 is the disc structure schematic diagram that the utility model autoclave film hangers forms fixture;
Fig. 4 is the fixing pin structural representation of the utility model autoclave film hangers;
Fig. 5 is the front view that the utility model autoclave film hangers assembles sample;
Fig. 6 is the vertical view of the utility model autoclave film hangers.
Embodiment
Below in conjunction with drawings and Examples, a kind of autoclave corrosion test of the present utility model is described further with sample film hangers.
Referring to Fig. 1～Fig. 6, autoclave corrosion test of the present utility model comprises that with sample film hangers upper end disc 1 ﹑ embeds end disc 6 under disk 4 ﹑ of sample, fixing pin 8 and with the supporting hexagonal nut 9 of fixing pin 8.
The disk 4 that embeds sample is superimposed upon above lower end disc 6, and 3 fixing pin hole alignment, insert respectively fixing pin hole 3 one end of 3 fixing pins 8, then with hexagonal nut 9, fix respectively.The disk 4 that again another is embedded to sample is enclosed within the other end of fixing pin 8.Sample 10 can insert different sample fixing 5 as required.Place after sample 10, upper end disc 1 is pressed in above the disk 4 that embeds sample, 3 alignment of fixing pin hole, install hexagonal nut 9 and fix.
Fig. 5 is the front view that installs the film hangers after sample, and Fig. 6 is the vertical view that installs the film hangers after sample, finally film hangers is arranged on above the shaft of autoclave.
The above; it is only preferably embodiment of the utility model; but the scope of the utility model protection is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
