Leak test for HSD Fuel Tank

[pras ari]

Dear Sir,

Please advise me about leak test (hydro-test) of HSD Fuel Tank, I have 2 (two) tank with capacity 1400 KL, We will held Leak test but but site condition and around very difficult to get water as much as 2800 kilo liters.

Is any method for substitute leak test? may be NDT or pneumatic test?

Thanks & Regards

Winarko

Dear Winarko,

You can conduct pneumatic test if only for leak test, but must be concerned to pressure not too high. Also difficult for find leak point (yo can use soap in water).

Best regards

Dear Winarko,

As per API 650, Please refer the alternative testing If sufficient water not available in the article 7.3.5 testing of shell, point no -2.

"2. If sufficient water to fill the tank is not available, the tank may be tested by (1) painting all of the joints on the inside with a

highly penetrating oil, such as automobile spring oil, and carefully examining the outside of the joints for leakage; (2)

applying vacuum to either side of the joints or applying internal air pressure as specified for the roof test in 7.3.7 and carefully

examining the joints for leakage; or (3) using any combination of the methods stipulated in 7.3.5, Subitems 1 and 2.

Regards,

Oarag.

Mr Winarko,

Please share the approved GAD from the Client to clarify further.

Hydro test is proof test, can not be waived off unless Client agrees. Require also calibration of settled liquid on the bottom plate slope.
