grounded tanks
Tanks obove ground are normally designed for inside pressure.
PROFILEEN ® tanks can be used for high concentrated
and aggressive chemicals as well for temperatures up to
60° C.
The
construction of bottom and cover can be made conventional
(with plates and stiffness) or according to the spherical
principle developed by bauku. A high stiffness of the
bottom- and cover construction is created by the swelled
areas of the lock.
The
wall thickness of the tanks can be produced graded -
that means the wall of the part below is thicker than
the upper part of the tank (hydrostatic pressure). The
tank wall can also be made with an
Of
course liquids can also be stored underground. In the industry
this principle is used for water
for fire fighting tanks or emergency
tanks .
Both
systems must be able to store aggressive chemicals. In
difference to the retention tank in the communal area
(see sewer
technology, retention tank systems) a good hydraulic
or self-cleaning system is not so important - here the
underground tanks are exactly fitted to the conditions
of the building. For such tanks the inside pressure of
the water level is not any longer the important criterion
for the design. But it must be designed for all kinds
of loads caused by bottom, ground water and traffic. Water for fire fighting
tanks -
or emergency tanks can also be equipped with the leak
warning system made by bauku (see sewer
technology, double wall system).
Every tank- regardless of the installations - is delivered
with extrusion weld joint on the welds in order to meet
the requirements of the safety of the pipe connections
in this area.
