GRP (glass fibre reinforced plastic) tank technology is now
accepted as standard in virtually every industry - from chemicals
to food and water, microelectronics and offshore oil and gas.
|
The available sizes for these standard tanks is from
5000 to 160,000 litres capacity and from 2000 to 4111mm
internal diameter (to suit standard mandrels).
Forbes are able to manufacture this range of GRP storage
tanks using a variety of different specification materials
selected for the appropriate chemical resistance. The
company will always endeavour to recommend the most
cost effective solution to customer requirements.

Filament winding manufacturing techniques do not produce
the ideal glass/resin ratio for process plant applications,
so, therefore, Forbes invested in a massive installation for
the production of cylindrical GRP shells by the 'chop-hoop'
winding process.
Automated controls constantly monitor the rate of deposition
of both glass and resin and provide detailed quality records.
The laminate is particularly strong and economical and combines
the advantages of winding and spraying techniques - notably
considerable multidirectional strength and enhanced inter-laminar
shear when compared to filament winding.
All Forbes GRP tank products are designed and constructed
to comply with BS4994:1987 - THE DESIGN AND CONSTRUCTION OF
VESSELS AND TANKS IN GLASS REINFORCED PLASTICS.
BS4994 covers the design, manufacture, transport and installation
of tanks and vessels in GRP materials. It is an extremely
thorough and stringent standard but does not cover any aspect
of the manufacture of tanks in other materials such as metals
or freestanding thermoplastics.
Where necessary, tanks will be post-cured in accordance with
the resin manufacturer's specifications, to ensure optimum
physical and chemical properties in order to achieve maximum
performance from the laminates. Forbes' massive post-curing
oven - fitted with a calibrated chart recorder - is over 5
metres in diameter and 13 metres long. It is capable of sustaining
temperatures in excess of 100°C over long periods.
Forbes standard PVT range of tanks offer superb value for
money. Semi-automated manufacturing techniques also ensure
low cost competitive products.
