Service life of fixed, internal & external floating roofs
Service life of fixed, internal & external floating roofs
(OP)
Dear All, Good day,
I would like to know how much is the lifetime of the API storage tanks roofs(is there any thing related to that in API?).
Actually, i saw a fixed conical roof built in 1979 before two days. Some of supporters underneath the roof has been bulked & bended.
Is that mean the steel network underneath the roof not any more strong enough?.

API doesn't address service life or require design for a specific service life.
If there is a known corrosion rate, it can be used to estimate remaining service life, time to next inspection, etc., but that is not a fixed constant.
