Description
Technical field
It the utility model is related to Produced Water In Oil-gas Fields, Ngi process field, and in particular to a kind of average corrosion rate dynamic measure dress
Put.
Background technology
Produced Water In Oil-gas Fields, Ngi has stronger corrosivity due to having the characteristics that high salinity, high concentrtion, low pH.In order to
The corrosion condition of produced water treatment system is solved, is provided for the selection of equipment, tubing and anti-corrosion mode according to, it is necessary to determine medium
Average corrosion rate.
Average corrosion rate measure is to hang over test piece in water treatment system, under normal production conditions, is taken out after 30 ± 2d,
Average corrosion rate is calculated according to the loss amount of test piece before and after experiment.Oil and gas station average corrosion rate measure is more using indoor at present
Static steel or hanging film scene mode, indoor static lacing film be by test piece it is closed hang on it is bottled extraction water sample in, hanging film scene
It is to hang on test piece in water treatment system storage tank, both modes have the following disadvantages：
（1）Indoor static lacing film mode is carried out under static oxygen barrier state, is not inconsistent with the actual motion state at scene；
（2）Though lacing film mode can react presence states in storage tank, input test piece surface at initial stage is commonly present i.e. by oil film bag
The phenomenon wrapped up in, strip form layer protecting film, it is also difficult to truly react the average corrosion rate of recovered water.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above, there is provided a kind of average corrosion rate dynamic measure device, is applied to
Produced Water In Oil-gas Fields, Ngi processing system average corrosion rate determines.
The technical solution of the utility model is：A kind of average corrosion rate dynamic measure device, is arranged at water treatment system and enters
On water pipeline, including bypass line, the bypass line both ends are connected in water treatment system back with water inlet line, the bypass line
Suspension arrangement is provided with, the suspension arrangement is used to hang test piece, and test piece is placed in bypass line.
The suspension arrangement includes flange short tube, closure and chaining, and described flange short tube one end connects with bypass line,
The flange short tube other end is connected with closure, and the chaining is connected on closure 5, and the test piece is connected to chaining free end,
And test piece is placed in bypass line.
The closure is connected with flange short tube by flange.
The chaining adjustable in length.
The inlet and outlet of the bypass line is equipped with control valve.
The bypass line is connected with water treatment system back with water inlet line by flange.
The technical solution of the utility model there is provided a kind of average corrosion rate dynamic measure device,
The beneficial effects of the utility model：
This average corrosion rate dynamic measure plant area provided by the utility model is small, and in-site installation is simple, by test piece
It is placed in the real running environment of system fluid, reflects the etch state of test piece, test piece dress takes conveniently, does not influence water treatment system
Normal operation, and device is repeatable utilizes.
The utility model is described in further details below with reference to accompanying drawing.
Brief description of the drawings
Fig. 1 is the scheme of installation that the utility model average corrosion rate dynamic determines device；
Fig. 2 is the structural representation that the utility model average corrosion rate dynamic determines device.

Embodiment
Embodiment 1：
In order to overcome disadvantages mentioned above, present embodiments provide a kind of average corrosion rate dynamic as depicted in figs. 1 and 2 and determine
Device, it is arranged in water treatment system back with water inlet line 2, including bypass line 1, the both ends of bypass line 1 are connected to water process
In system back with water inlet line 2, the bypass line 1 is provided with suspension arrangement, and the suspension arrangement is used to hang test piece 3, and test piece 3
It is placed in bypass line 1.
Recovered water in water treatment system back with water inlet line 2 passes through from bypass line 1 so that and test piece 3 is soaked in recovered water,
So as to obtain the etch state of test piece 3.
This average corrosion rate dynamic measure plant area of the present utility model is small, and in-site installation is simple, and test piece is placed in
In the real running environment of system fluid, reflect the etch state of test piece, test piece dress takes conveniently, is not influenceing water treatment system just
Often operation, and the repeatable utilization of device.
