Tank Types - Dry Bulk Storage
Bolted Smoothwall Tanks - Available in
precision FP (flat panel) construction, the industrial "smoothwall" bolted tank
remains the economical product of choice for dry bulk materials, when
storage requirements exceed shop-welded tank requirements (i.e., greater
than 8000-10,000 cubic feet of storage). 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 80,000 cubic feet. Flat bottom capacities range up to 2
million cubic feet of storage.
Hybrid Storage Tanks &
Silos – Combines the best qualities of bolted FP, field-weld and
concrete construction together in one product. The hybrid silo has
become a preferred storage tank design when storage volume requirements
exceed bolted FP designs. Hybrid construction can utilize a bolted FP
sidewall with a field-weld deck or hopper. Other hybrid designs utilize
concrete floors elevated on structural steel and field-weld designs with
bolted tank components. The hybrid silo is uniquely tailored for the
application. Many large volume applications designed for functional mass
flow discharge utilize a hybrid tank design.
Applications: Cement, fly ash, coal, limestone, lime, aggregates,
minerals, chemicals & misc. dry other
- Hopper capacities from 20,000 – 150,000 cubic feet
- Shop-controlled quality
- Modular construction requires field assembly
- Decreased field installation timeframe
- Factory applied powder coating systems
Field Welded
Tanks - Available in API 620 & API 650 designs, the
field-welded tank remains the product of choice in select dry bulk
storage applications. Typical applications include: storage
requirements that require heavier tank designs than bolted smoothwall tanks offer, storage capacities in excess of 70,000 cubic
feet when hopper bottom discharge is required, power market, heavy
and abrasive bulk material applications. Quality field-weld
fabrication is evidenced by following code requirements including
radiograph examination, etc.
Drive-through Skirt tanks – The most
economical choice for truck load-out applications. Capacities range up to
150,000 cubic feet. Bolted FP Tank construction is the new industry
standard for industrial process applications.
Shop Welded Tanks – The tank of choice for
the storage of dry bulk materials up to capacities of 10,000 cubic
feet. Also, the typical approach required for food grade storage, when
bolted panel connections are not allowed.
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 10,000 cubic feet capacity in one-piece construction. Quality
welded aluminum silos are an economical alternative to coated carbon steel
tanks.
TC Gravity Blend Tank – 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. |
