ASME Pressure Vessels and Water Storage Tanks - page 59

Insulation Systems
The storage tank and saddles must be
designed to accommodate loadings
resulting from the weight of the tank
and its contents, external equipment,
and environmental conditions. In areas
subject to damaging wind, water, or
earthquakes the design of the
supporting structure and connections
for the storage tank shall require
special engineering consideration.
The design and construction of tank
supports and foundations is critical
and should only be undertaken and
supervised by competent professionals.
1. Do not rely on tack or seal-welded saddles
as a means for securing a tank in flood prone
areas. A hold-down system, connected to an
adequately sized anchor pad is recommended.
A properly designed hold-down strap system
with adequately sized reinforced concrete
hold-down pad is recommended to secure a
tank in flood prone areas.

Custom thermal insulation can be
applied to tanks and vessels to help
reduce energy costs associated
with heating or maintaining heat in
the process for efficient and
effective operation.
We have multiple methods for
insulating tanks and vessels depending
on your specific requirements:
External Spray-on Insulation System
• A complete 360º wrap of
sprayed-on insulating material
(nominal thickness- 1.5")
• A protective finish coating over
the foam insulation to prevent
UV damage
Injected Insulation System
• A complete 360º second wrap,
steel skin
• The interstice is injected with
a special time-activated foam
insulating material that expands
to completely fill all voids and
eliminate air pockets
External Batt with Jacket
Insulation System
• A complete 360º wrap with
insulating batts of mineral wool,
fiberglass or ceramic material
• A complete 360º wrap with
a 24-26 gauge aluminum skin
to ensure insulation integrity
