A tank

As I said earlier, first check the vents for faults or improper set points.

[Ankit_Kumar]

PVRVS were checked & found ok. Set point is 150 mm WC

Well that is 5.9" wc which is not unusual for a tank blanketing setpoint. However, you stated that the vents did not actuate. So that suggests that the tank failed at less than this pressure. Do you agree?

I didn't get what you want to say regarding 5.9 " WC blanketing set point. 

 

Yeah apparently it means tank failed at less than this pressure.

You said that the vents were functional, did not actuate, and the set point was 5.9" w.c. This is not an unusual situation.

 

So, since the vents are okay and the set point is not unusual what that says to me is that the tank failed due to a pressure less than 5.9" w.c.

 

The next question for me to have answered is that should that tank have not failed under a pressure of 5.9"w.c.? Then,

 

What pressure should that tank have been able to withstand?

 

Was there a mechanical fault in that tank?

 

Possibly the system would have survived if the vents were set at a lower pressure.

 

Possibly that tank and that tank design was inappropriate for the application. ?

 

You see that you have a lot of questions to answer before moving forward with new or repaired equipment.

 

Best wishes to you.

 

Possibly that tank was not designed properly?
