API-653 SECTION 10
When a tank is to be dismantled and reconstructed at another location , what size are
the roof, shell and bottom plates cut? - Answer cut all plates to any size that is readily
transportable to the new site.
If a reconstructed tank's bottom is to be removed and scrapped and the shell to bottom
weld is 1/2 inch, how high above the tank's bottom would you cut the shell plate? -
answer1"
When a 5/8 inch thick double butt welded tank shell plate(weld width is 1/2") is
dismantled for reconstruction, how much metal must be removed from each side of the
weld to remove the HAZ? - answer1/4"
Tanks and their structural attachments shall be welded in accordance with the
processes specified in: - answer API Standard 650 and the requirements of API 653
No welding may be performed during the reconstruction of a tank if the temperature of
the base metal is less than: - answer0 degrees F
On a reconstructed tank, when the temperature of the base metal is between 0 degrees
F. and 32 degrees F., or the thickness of the tank plate is in excess of 1 inch, the base
metal within 3 inches of the place where welding is to be started shall be heated to a
temperature warm to the hand (approximately_______) before welding. - answer140
degrees F
On a reconstructed tank, no welding of any kind shall be performed when the surface of
the parts to be welded : - answerare wet from rain,snow,or ice.
On a reconstructed tank, the maximum undercutting of base metal for welded vertical
butt joints is: - answer1/64 inch.
On a reconstructed tank,the maximum undercutting of base metal for welded horizontal
butt joints is: - answer1/32 inch.
On a reconstructed tank, according to API Standard 653,reinforcement of new welds on
all butt joints on each side of the plate shall not exceed the following, for plate thickness
_< 1/2 inch,the maximum reinforcement thickness for"vertical" joints is: - answer3/32
inch
On a reconstructed tank, according to API Standard 653, reinforcement of new welds on
all butt joints on each side of the plate shall not exceed the following for plate thickness
