solution
1. when tanks arrive at the job site, how should they be unloaded?
lifted off with a cable attached to the tank lifting lugs
As an alternative lifting method, should a cable or chain be wrapped around the
tank?
No, Never!
When you are lifting a tank, using the lifting lugs, which of these procedures
should be followed?
attach a triangle cable through the lugs with no more than a 30 degree angle from the
center line.
After you unload a new tank on a clean level surface at the job site what else
should you do prior to inspection and pre-testing?
Chock the tank to prevent it from Rolling
which of the following items should be physically checked for damage or
imperfections at the job site?
Piping (steel and fiberglass)
Fittings, Vents, Fillboxes, anodes, ECT..
The tanks themselves
(ALL OF THE ABOVE)!
STI-P3 tanks are delivered with shipping plugs in tank openings. What should be
done to these plugs prior to testing?
remove the plugs and replace them with a standard threaded plug that is properly
doped
should dielectric bushings be installed in all openings of an STI-P3 tank?
yes on all openings
what is the maximum air pressure to which a steel tank should be subjected in a
pre-installation test?
5 pounds
for fiberglass reinforced plastic (FRP) tanks up to 12 feet in diameter what is an
acceptable air pressure to which the tanks may be subjected in a pre-installation
test?
3 pounds
for FRP tanks over 12 feet in diameter what is the maximum air pressure to which
the tanks should be subjected in a pre-installation test?
3 pounds
when you are conducting an air test on a tank the type of gauge that should be
used is?
a pressure gauge with a maximum limit of 10 to 15 PSIG
the proper procedure for conducting a pre-installation air test of a steel tank is
to?
apply 3 to 5 pounds of pressure and soap all surfaces and weld seams visible through
the coating while inspecting for bubbles.
, what is the proper procedure for conducting a pre-installation air test of an FRP
tank Under 12 feet in diameter is to....
apply 3 pounds of air pressure and soap all surfaces while inspecting for any sign of a
leak either audible or visible in the form of bubbles on the surface
a double-walled steel tank build in accordance with UL standard 58 is?
requires air testing of the interstitial space prior to installation
the proper procedure for conducting a pre-installation air test of a double-walled
tank is to?
pressurize the inner tank monitor the pressure for one hour and then pressurize the
space between the inner and outer tanks with the air from the inner tank
when shipped a steel tank is covered with a coating that is an important part of
the tanks Corrosion Prevention system. "holidays" which show up in the coating
at the installation site should?
should be touched up with a compatible coating after proper surface preparation
touch up of holidays in a steel tank coatings at the installation site should be
done.......
according to the manufacturer's instructions
dielectric bushings are usually made of what?
non-metallic material
factors to consider in determining the size shape and depth of a tank excavation
include what?
*the tank manufacturers recommendations
*the requirements for compacting bedding and backfill as well as stability of the soil
*the depth of cover
AKA all of the above
in the absence of local requirements the recommended minimum distance
between a tank excavation and adjacent structures or property lines is how many
feet?
5 feet
reinforcement of a steel underground tank may be required by the tank
manufacturer if
the burial depth is greater than the tank diameter
according to FRP tank manufacturers specifications the burial depth for an FRP
tank should not exceed how many feet?
7 feet
when installing a cathodically protected steel tank you should
make sure the excavation is free from material that could cause damage to the coating
when installing dielectric bushings in a cathodically protected steel tank prior to
placing the tank in the excavation you should
make sure that no electric current can pass through the dielectric flanges or bushings
industry codes as well as the specifications of individual manufacturers do not
entirely agree as to the minimum space that should be maintained between tanks
and stalled in stable soil conditions. what ranges of minimum spacing between
tanks derived from various industry codes and manufacture specifications which
range is most accurate.
