FINAL SETTING

INSPECTION MANHOLE COVERS – use a plate or other similar material box-type extension to protect the inspectionmanhole covers and make them accessible. In case of use of heavyweight material ( e.g. cast iron or concrete ) orwith vehicular traffic avoid that the load falls on the tank. On the surface mark the tank presence and size.

CONNECTIONS - make connections using elastic joints and/or flexible piping to favour ground settling.

FLAT BOTTOM VERTICAL CYLINDRICAL TANKSBefore starting any operation of tank installation check that the ground to lay it is smooth and well levelled.

Place the tank on a flat and well levelled concrete base. Anchor each tankleg to the concrete screed, using a suitable pressure cap, with the hole youfind on the base of each leg of the tank.

If the tank has to be installed outdoor it will be necessary to find the mostsuitable anchoring way, taking also into consideration wind action.

GENERAL INSTRUCTIONFOR INSTALLATION

UNDERGROUND HORIZONTAL TANKS

HANDLINGUse appropriate means to lift the tank and use the hooks

you find on it.

Handle the tank only when it is empty.

EXCAVATIONMake an excavation of appropriate size ( consider about

80 cm more than the tank maximun size).

FOUNDATIONMake a 20÷25 cm concrete base at the bottom of the

excavation and then put a sand bed of about 25-30 cm..

Level and remove any bump to ensure a good tank stability

and protection. Position the tank perfectly horizontal and

anchor it to the concrete base by means of belts and / or

bands made of suitable material for this use. Do not use

any “ anti-rolling “ objects such as wedges, wooden planks,

etc. which could damage the structure of the tank during

the subsequent phases of abutment and filling.

SPECIAL CONDITIONSPRESENCE OF GROUNDWATER - In the case of a normally

empty tank , in order to avoid that it emerges from the

soil due to the hydraulic pressure, make a drainage using

a draining pipe, gravel of suitable granulometry and

discharge pipe.

PRESENCE OF CLAY SOIL – Cover the walls of the

excavation with a sheet made of filtering material the

kind of non-woven fabric to prevent that the clay seeps

through the interstices of the drainage.

TANKS

ORM tanks are manufactured to satisfy the many demands on liquid storage, thanks to a wide range of solutions related

to storage capacities, geometric shapes, type of installation. The possibility to use special polyester resins allows ORM

to manufacture tanks suitable for the storage of chemical aggressive products , even at high temperatures. ORM tanks

are complete with standard equipment customizable on request. Used material used GRP (fiberglass reinforced polyester

resin). GRP is a thermosetting composite with high compactness and resistance to chemical and biological agents,

which does not form flaking, does not release substances and does not collapse at temperature changes.

Tanks for the industry, made to order, satisfy multiple solutions

for chemical and industrial plants. The possibility to use

special polyester resins makes the tanks ORM suitable for

aggressive chemicals, even at elevated temperatures.

Tanks for winemaking and wine storage , are suitable for

the storage of liquid food, according to Ministerial Decree

21.12.2010 No. 258, thanks to the particular chemical

composition of the resin used and the final treatments.

T A N K S F O R W I N E

ABUTMENTPEDESTRIAN TRAFFIC

The tank must not be buried at a depth more than 30 cm.

Lay the tank on a sand bed thick not less than 15:20 cm.

Begin the gradual filling of the tank and simultaneously

make the abutment, using wet sand (or stabilized) in layers

of about 30 cm, taking care to compact each layer before

proceeding with the laying of the next one.

Once you have finished the backfilling, close the excavation

with land thick not more than 30 cm. For bigger excavations

proceed as follows:

• Up to 50 cm. bury the upper part with lightweight

material ( e.g. expanded clay )

• Over 50 cm. proceed as mentioned in VEHICULAR TRAFFIC

VEHICULAR TRAFFIC

Fill the tank up to 1/2 of its capacity and simultaneously

make the abutment with concrete. Make a concrete vault-

or slab structure ( see example in figure ), which conveys

the loads coming from above directly to the concrete

abutment, leaving the tank undamaged.

S E R B A T O I P E R A C Q U AT A N K S F O R W A T E R

Water tanks are suitable for the storage of liquid food,

according to Ministerial Decree 21.12.2010 No. 258, thanks

TANKS FOR INDUSTRY

ORM technology applied to GRP (fiberglass reinforcedpolyester resin), allows to manufacture storage tanksof large sizes and with exceptional features:

• high mechanical resistance• low thermal conductivity• low coefficient of expansion• chemical resistance to a large number of substances

used in industry• no toxicity and resistance to atmosferic agents• low cost of installation and handling• long service life

ORM tanks are widely used in the food industry (dairy,olive and seed oil, canning, etc.), chemical,pharmaceutical, petrochemical, textile, leather, paperand shipbuilding. ORM tanks also satisfy the technicaland tank installation requirements for fire protection.

ORM tanks manufacturing technologies are: hand lay-up, spray-up and filament winding. Tanks are made ofa first impermeable and anticorrosive (liner) layer ,which goes into contact with the liquid. It is realizedusing high resistance resins. The next layer, which is thetank supporting structure, is made by wrapping crosswiseand radially continuous fiber glass , soaked with resinand chopped fiber glass sprayed with a spray gun, togive the tank a very high mechanical resistance and ahigh safety coefficient. The third layer, rich in resin,protects the previous ones, forming a shiny and smoothsurface that gives the product excellent characteristicsof resistance to atmospheric agents.

40 years experience in manufacturing and a continuouscommitment to research and development, allows ORMto offer the best assistance for the solution of problemsrelated to plant for any kind of industry. On request wemanufacture tanks on customer technical specificationsand equipped with all kinds of pipe fittings.

TANKS FOR INDUSTRY

ORM technology applied to GRP (fiberglass reinforcedpolyester resin), allows to manufacture storage tanksof large sizes and with exceptional features:

• high mechanical resistance• low thermal conductivity• low coefficient of expansion• chemical resistance to a large number of substances

used in industry• no toxicity and resistance to atmosferic agents• low cost of installation and handling• long service life

ORM tanks are widely used in the food industry (dairy,olive and seed oil, canning, etc.), chemical,pharmaceutical, petrochemical, textile, leather, paperand shipbuilding. ORM tanks also satisfy the technicaland tank installation requirements for fire protection.

ORM tanks manufacturing technologies are: hand lay-up, spray-up and filament winding. Tanks are made ofa first impermeable and anticorrosive (liner) layer ,which goes into contact with the liquid. It is realizedusing high resistance resins. The next layer, which is thetank supporting structure, is made by wrapping crosswiseand radially continuous fiber glass , soaked with resinand chopped fiber glass sprayed with a spray gun, togive the tank a very high mechanical resistance and ahigh safety coefficient. The third layer, rich in resin,protects the previous ones, forming a shiny and smoothsurface that gives the product excellent characteristicsof resistance to atmospheric agents.

40 years experience in manufacturing and a continuouscommitment to research and development, allows ORMto offer the best assistance for the solution of problemsrelated to plant for any kind of industry. On request wemanufacture tanks on customer technical specificationsand equipped with all kinds of pipe fittings.

GENERAL INSTRUCTIONFOR INSTALLATION


HANDLINGUse appropriate means to lift the tank and use the hooks

you find on it.

Handle the tank only when it is empty.

EXCAVATIONMake an excavation of appropriate size ( consider about

80 cm more than the tank maximun size).

FOUNDATIONMake a 20÷25 cm concrete base at the bottom of the

excavation and then put a sand bed of about 25-30 cm..

Level and remove any bump to ensure a good tank stability

and protection. Position the tank perfectly horizontal and

anchor it to the concrete base by means of belts and / or

bands made of suitable material for this use. Do not use

any “ anti-rolling “ objects such as wedges, wooden planks,

etc. which could damage the structure of the tank during

the subsequent phases of abutment and filling.

SPECIAL CONDITIONSPRESENCE OF GROUNDWATER - In the case of a normally

empty tank , in order to avoid that it emerges from the

soil due to the hydraulic pressure, make a drainage using

a draining pipe, gravel of suitable granulometry and

discharge pipe.

PRESENCE OF CLAY SOIL – Cover the walls of the

excavation with a sheet made of filtering material the

kind of non-woven fabric to prevent that the clay seeps

through the interstices of the drainage.

TANKS

ORM tanks are manufactured to satisfy the many demands on liquid storage, thanks to a wide range of solutions related

to storage capacities, geometric shapes, type of installation. The possibility to use special polyester resins allows ORM

to manufacture tanks suitable for the storage of chemical aggressive products , even at high temperatures. ORM tanks

are complete with standard equipment customizable on request. Used material used GRP (fiberglass reinforced polyester

resin). GRP is a thermosetting composite with high compactness and resistance to chemical and biological agents,

which does not form flaking, does not release substances and does not collapse at temperature changes.

Tanks for the industry, made to order, satisfy multiple solutions

for chemical and industrial plants. The possibility to use

special polyester resins makes the tanks ORM suitable for

aggressive chemicals, even at elevated temperatures.

Tanks for winemaking and wine storage , are suitable for

the storage of liquid food, according to Ministerial Decree

21.12.2010 No. 258, thanks to the particular chemical

composition of the resin used and the final treatments.

T A N K S F O R W I N E

ABUTMENTPEDESTRIAN TRAFFIC

The tank must not be buried at a depth more than 30 cm.

Lay the tank on a sand bed thick not less than 15:20 cm.

Begin the gradual filling of the tank and simultaneously

make the abutment, using wet sand (or stabilized) in layers

of about 30 cm, taking care to compact each layer before

proceeding with the laying of the next one.

Once you have finished the backfilling, close the excavation

with land thick not more than 30 cm. For bigger excavations

proceed as follows:

• Up to 50 cm. bury the upper part with lightweight

material ( e.g. expanded clay )

• Over 50 cm. proceed as mentioned in VEHICULAR TRAFFIC

VEHICULAR TRAFFIC

Fill the tank up to 1/2 of its capacity and simultaneously

make the abutment with concrete. Make a concrete vault-

or slab structure ( see example in figure ), which conveys

the loads coming from above directly to the concrete

abutment, leaving the tank undamaged.

FINAL SETTING

INSPECTION MANHOLE COVERS – use a plate or other similar material box-type extension to protect the inspectionmanhole covers and make them accessible. In case of use of heavyweight material ( e.g. cast iron or concrete ) orwith vehicular traffic avoid that the load falls on the tank. On the surface mark the tank presence and size.

CONNECTIONS - make connections using elastic joints and/or flexible piping to favour ground settling.

FLAT BOTTOM VERTICAL CYLINDRICAL TANKSBefore starting any operation of tank installation check that the ground to lay it is smooth and well levelled.

Place the tank on a flat and well levelled concrete base. Anchor each tankleg to the concrete screed, using a suitable pressure cap, with the hole youfind on the base of each leg of the tank.

If the tank has to be installed outdoor it will be necessary to find the mostsuitable anchoring way, taking also into consideration wind action.
