we have contrated the repair including quality surveillance from third entity for quality, repair should be according API 653.
Roundness only meausure one feet above bottom, so outside the area.
what we are looking is distortion tolerances in API 653?' maybee in any questions queries??
i will...
my question is the tolerance of acceptance.
In API 653 i dont find any indication about tolerances of acceptance of deviation of shell to bottom weld.
The FFS (API 579) is running in parallel.
Banding i understand it´s not the best criteria.
the deformation stars more of less 270 mm from the...
My problem i do t have any poi t in 653 to clearly not accept this deformation.
They use banding shell not more 13 mm. For that is acceptable according 653?
We apply peaki g or banding in the weld shell to bottom??
I dont find any tolerance in 653 refering the alinement shell to bottom.
With...
The bottom extends 50 mm as requested api.
Some opinions tell me to cut and reweld.
But where i have fundamentatuon in API?
The contractor tell me that is according to API 653 as requested.
Also if cut the weld but the shell will keep distortion.
the deformation stars more or less 270 mm from the bottom.
roundness cannot aply because meausure is above 1 feet (out of the affected area)
plumbness from astm limits 28 mm, but aproving a deformation in the last part of the shell near the critical zone semms nonsense.

Hello,
in a repair of a tank the shell suffer a distortion in the connection to the bottom anular plate.
the distortion is 360º , 9 to 13 mm (1/2") to the inside.
I cannot find anything specific to this in API 653, to reference.
most similar is banding between shell limit to 13 mm (1/2") in...
Snorgy,
in my opinion:
Connecting tanks to flare or incinerator
you can have O2 inside the tank, and can achieve a dangerous situation. your explosion triangle have 2 points it only needs one more (air)
VRU
We have a VRU and it´s a expensive equipment to buy and maintain
recapture N2
cost lot...
Hello,
If i want to build/reconstruc a tank to operate with hydrocarbons i need to know if i need to install:
1) External floating roof, internal floating roof with conic roof, or simply a conic roof. We should choose in function of the need to reduce emissions
There is any code that can guide...
In Portugal i can recomend some

i dont have any comercial connection to them, we frequently buy them collums,drums and exchangers
s reading a ealier thread483-271182 about sour water feed tank
and studing this question
and i dont understod if:
putting a floating roof+fixed roof shall keep the layer of diesel?
anyone send this to the amine with results?
anyone think to use API 620 instead od API 650 to design the tank with...
Hello,
because of leaks in emergency vent´s we are thinking of change the seal material from Teflon to Viton.
The Viton allows better seal, but i think it can have the problem of stick
Anyone with similar problem?
