Dry Bulk Hopper Tanks
 Bolted
API Flanged Panel (Smoothwall) - The tank of choice for the storage of
dry bulk materials. Hopper gravity discharge is available in a variety of
designs including skirted tanks, drive-through skirted tanks, tanks on
structures, tanks on load cells and tanks elevated on structural
legs. Hopper capacities range from 900 cubic feet up to 150,000 cubic
feet. Flat bottom capacities range up to 2 million cubic feet of storage.
Shop Welded Tanks – The tank of choice for the
storage of dry bulk materials up to capacities of 12,000 cubic feet. Also,
the typical approach required for food grade storage, when bolted panel
connections are not allowed. Columbian TecTank welded tanks as
manufactured in Winchester TN, are the industry standard for performance
in the dry bulk market.
Drive-through Skirt tanks – The most
economical choice for truck load-out applications. Capacities range up to
150,000 cubic feet. Bolted API Flanged Panel design is the recognized
standard for industrial process applications.
LV (large volume) Flat Bottom Silos –
Available in sizes that will store up to 2,000,000 cubic feet of dry bulk
material. Based upon the material stored, a variety of unloading
discharge systems are available.
Bolted Flat Panel (FP) Designs – Utilized for
liquid and flat bottom grain applications. Powder and liquid coatings are
typically designed for immersion service.
Corrugated Flat Panel (FP) Designs – Utilized
for non-process grain storage. Galvanized interior and exterior finish are
typical.
Stainless Steel Storage Tanks– Tank
construction is available in 304, 316 & 316L materials with various
polished surface profiles. SS construction should be evaluated when
product purity, flow inducement and/or chemical attack issues exists with
the stored material. Stainless construction is the high price storage
approach.
Aluminum Storage Tanks – Quality containment
(fabrication satisfies ASME Section VIII requirements) required in select
food, chemical and petrochem applications. A variety of alloy designations
are available with 5052 H32 material being the most common and versatile
in dry bulk storage applications. Shop welded aluminum tanks are available
up to 12,000 cubic feet capacity in one-piece construction. Quality welded
aluminum silos are an economical alternative to coated carbon steel tanks.
DFC Blend Tank – Direct Flow Channel blend
silos are utilized in the plastics market by producers, compounders and
processors to reduce variables in the process stream. Blend tanks smooth
out plastic resin variables associated with melt index, color variation
and particle size |
