The filling water test of large-size stainless steel groove tank under external hot environment.
Summary of the invention
The purpose of the present invention is to propose large-size stainless steel groove tank filling water test side under a kind of safe and reliable hot environment
Method.
To achieve the above object, the technical solution of the invention is as follows：
A kind of large-size stainless steel groove tank filling water test method under hot environment, 2 ten thousand stere of stainless steel sink tank volume, groove tank diameter
The high 24.55m of 38m, groove tank, tank skin high 19.1m after stainless steel groove tank is built, carry out filling water test, it is characterised in that including
Following steps：
A, before filling water test, all attachmentes and other and tank body welding component should all complete；All and leak test
Related weld seam, must not brushing paint；
B, water examination
Filling water test must carry out chloride ion, chloride, pH value with water and detect, it is necessary to meet code requirement；
C, tank body foundation settlement is tested
It should reinforce tank body foundation settlement survey in filling water test, if the sedimentation not allowed occurs for tank body basis, water-filling should be stopped, to
After processing, it can continue to test；During water-filling and water-discharging, loophole should be opened, and tank body basis must not be made to soak；Tank body base
Observation point is set by design requirement in tank skin lower part in plinth settling test, it is desirable that any tank body circumference differential settlement 13mm or entirety
50mm is settled, should report owner, and stop water-filling, it is to be processed；
D, the intensity and leak test of tank skin
After being filled to design highest liquid level and keeping for 24 hours, make the intensity and leak test of tank skin, it is tank skin ne-leakage, without exception
It is deformed into qualification；If keeping liquid level 300mm lower than leakage, and repaired in strict accordance with welding procedure it was found that should discharge water when infiltration
It mends；
E, the intensity and leak test on fixed top
So that tank headspace is filled air and boost to test pressure, tank deck deformation without exception, weld seam ne-leakage is qualification；Fixed top
Intensity and leak test after, should make to communicate with atmosphere inside groove tank immediately, be restored to normal pressure.
Large-size stainless steel groove tank filling water test method can also use technical measures below under hot environment of the invention
To further realize.
Method above-mentioned, wherein the length of the repairing is no less than 50mm, same position number of rewelding is no more than two
It is secondary.
Method above-mentioned, wherein the intensity on the fixed top and leak test are causing the weather of high temperature variation not
Preferably carry out.
Method above-mentioned, wherein the filling water test is clean fresh water with water, water quality need to test, and water temperature is not less than 5
℃。
After adopting the above technical scheme, under hot environment of the invention large-size stainless steel groove tank filling water test method have with
Lower advantage：
1, the filling water test step that complete set is proposed to stainless steel groove tank anti-corrosion, can monitor tank bottom tightness, tank bottom intensity
And intensity, stability and the tightness of tightness and fixed top；
2, perfect anticorrosive quality guarantee system is established, it is mutual using Unite States Standard and Saudi Arabia SABIC standard in the construction process
In conjunction with the check criteria being complementary to one another again, a series of experiments and the observations such as the settlement observation of stainless steel sink tank base are carried out, is ensured
2 ten thousand stere stainless steel groove tank filling water test result of Saudi Arabia meets design specification requirement.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
