Re: [MW:17604] Regarding Kereosene Leak test

Friends,

I checked the procedure that we follow. We fill the cast iron oil sump with Varsol (Varsol fluids are traditional solvents that are also known as mineral spirits or white spirits. These fluids have been widely used in industry for decades, developed to replace kerosene in solvent applications.)

The hold up duration is 8 hours minimum for cast iron sump. For your case it may be 4 hours minimum. This is to best of my knowledge.

Regards,

Vinod

Dear Vinod

 

Thnaks for Suggestion ,

 

ButI have One Doubt , If you waited 24 hours On chock Surface for inspection.

There shall be possiblity to vaporize spray kerosense or Warsol in environment During 24 hours.

so no body inspector will allow  24 hours to inspect .

 

so as per my oponion , three hours is maximum time  for any liquid to comeout from  leak surface. and UP to 3 hours we can wait .

 

if you have any Concern on these  topic .let me know.

 

Thank You Very Much

 

Regards

Even kerosene is not allowed from environment or safety reasons.
In USA they use Warsol (kerosene like light gravity solvent).
If kerosene is not a concern you can apply white chalk (white wash) in outer periphery, fill with low gravity liquid eg kerosene and check outer surface after 24 hours.
If there is a leak, you will visually find dark wet spots.

It is generic test. just check for the leak on the otherside.

Alternative is Smoke bomb test (but presenlty not much in use)
