Riveted Shell Leaks 2

[Cristian N]

Guys,
does anyone have experience with riveted shell leaks for an in-service tank?

Typically what is the best course of action?


Tank Details:
Material : A283-C
Year Built: 1929
Courses: 5 Bottom three courses have 3 rivets while top two courses have 2 rivets
Height : 29.6'
D: 117'
Service : Gasoline

primary bottom replace with welded bottom.
Doesn't look like it ever had a concrete ring foundation.

See attached pictures

Just curious: Are the following previous threads

- External Settlement Surveys thread1452-482673
- Cosine Curve thread1452-483560
for this tank ?

This tank is more than 90 yrs old.. IMO, it deserves the right to stay at a Industry Museum for the remaining life..

My suggestion will be , abandon this tank and construct a new one complying the latest API 650 code..

MJCronin,

Of course.....Will be sure to keep the forum posted.

It is safe to say, that recurring maintenance costs and increased environmental and safety concerns dictate that riveted tanks be replaced with new, state-of-the-art storage tanks. If your company can't afford to replace the riveted tank, you should go out of business. If the tank fails, you will probably go out of business anyway.

If the tank is leaking gasoline out of the rivets, a lightning strike may set the tank on fire.

It is my understanding that, when God sends lightning bolts down to earth, to shake up and frighten the humans ....

He always targets leaking riveted tanks ....

Just sayin'......
