How to detect whether the device is being used out of range?
Thread Content
The design pressure of a certain pressure vessel is 0.5MPA, and the hydraulic pressure test when leaving the factory met the requirements without leakage. During the user's production process, a leakage accident occurred, and the user is suspected of over-pressure operation. Is there any way to detect this?
Carefully analyze the details of the leak. There is no other way. In addition, with the hydrostatic test report in hand, there is no need to worry.
Determine the cause of the damage based on the leakage point, and you have hydraulic pressure test data, so it should be fine. You can also conduct on-site survey with the customer to see if there is a possibility of overpressure, whether the safety accessories are complete, etc.
Whether the water pressure report is fully signed and executed according to the procedures, if it meets the standards, we will not be held responsible. Of course, it is not necessary to cooperate with the user to find the cause of the leak (in terms of equipment). After all, services now require three guarantees, and it is necessary to provide appropriate technical support.
The status of the safety valve can be checked: If the safety valve has tripped, it means there is a possibility of overpressure. ； If the safety valve does not trip, check whether the tripping pressure of the safety valve is normal. If it does not trip at the opening pressure, it means there is a problem with the constant pressure of the safety valve, and the equipment may also be overpressured.
It depends on the leak situation at the scene.
