Coast
Equipment & Services Company Bolted, Welded and Corrugated
Silos, In-plant Bins and Accessories:
Bolted Silos |
Bolted
silos are constructed of sidewall panels approximately
5’ wide by 8’ wide. These staves are precision
cut, formed and factory-coated. They are versatile enough
that we can produce tanks in sizes up to 200’ in diameter
and 200’ high, subject to design restrictions.
Our
bolted silos are designed to meet the requirements of heavy
usage. Hopper-bottom silos utilize a structurally designed
hopper-to-sidewall connection that is reinforced at the
hopper springline. Truck and rail drive-through skirt openings
are reinforced with heavy wall square and rectangular tubing
to increase stability.
Welded Silos |
Welded
silos are qualified to ASME Section IX. Shell seams
are full penetration welded using sub-arc welding processes
with copper backup. Other seams may e made with gas metal
arc welding, flux-colored arc welding or submerged arc welding,
as appropriate.
Standard
welded tank diameters range from 8’ to 14’ and
standard heights are 18’ to 72’. Welded silos
are typically shipped as single piece units, ready to install
upon arrival at the jobsite. However, when taller silos
are desired, sections can be shipped for welding onsite.
Skirted silos up to 12’ in diameter and 80’ long
can be shipped on self unloading trailers for domestic deliveries.
Corrugated Silos |
Corrugated
silos are constructed of galvanized steel and range
in capacity from 5,000 to 245,000 lbs., 6 ft. to 21 ft.
in diameter. These silos require minimal maintenance and
are highly resistant to weather conditions and industrial
pollution. They help eliminate the possibility of costly
production downtime due to interruption in material deliveries,
because you're assured of a good reserve supply. Plant efficiency
is increased because materials move from the bulk bins automatically
to points of need with a minimum of operator involvement.
