How to Install FRP

Unloading storage tanks and moving them to their final locations can be major operations. Before installing a tank, make sure the ground where it will be placed is level so that the pressure is evenly distributed within the tank. Concrete, sand, or pea gravel work well as flooring substrates. It is very important to make sure the floor has no jagged edges that the tank will sit on.

You will need a forklift or front-end
loader to position the tank and place it
upright once it is unloaded. Know how
much each tank weighs and make sure
you have a forklift that can handle the
weight. To move, strap tanks to the
forklift, and use spotters to bring
them indoors.

Knuckle booms that unload tanks from semi
trucks make your job much easier. Each tank
will have lift points near its top and along the
sides, and can be physically lifted straight up,
and then placed on the ground. The boom
operator then switches the hooking to the top
and brings the tank up vertically to allow the
forklift to move the tank indoors.

Valves and other plumbing fixtures are installed
after tanks are delivered. While there are many
choices for valves and fittings, be sure to chose
materials that are compatible with the materials
that will be stored in the tank. In addition, ask
the manufacturer how much compression force
(torque) you can apply on the fiberglass as you
tighten up the fittings and valves.
Once the system is plumbed, fill one of the
tanks with water for a day or two, and check for
leaks around the plumbing or through the tank.
Once a tank passes this test, simply pump the
water from that tank into the next tank and repeat
the process until you evaluate all your tanks.

A small leak from this tank’s manway allows the contents to accumulate on the concrete.

If the storage tanks remain outdoors, tie them
down to prevent the wind from tipping them
over and potentially cracking them or damaging
valves. Again, make sure to secure the tanks
to the ground with tie downs — just a couple
of inches of rain accumulating in an outdoor
containment area can lift tanks.
However, be careful not to over tighten the
tie downs. These are glassed in like all other
additions to the tank, and it’s possible to tighten
the cables so much that they pull the metal
hooks away from the tank. Tighten the cables
just enough to keep the tanks in place during
a storm. Check the cables annually for tension,
and retighten as needed.

Tie-downs can secure tanks in the event of flooding or high winds.
