Dual laminate tank technology is now accepted as standard in virtually every industry from chemicals to food and water, microelectronics and offshore oil and gas.
Forbes manufacture dual laminate storage tanks in various materials from 200 to 200,000 litres capacity. All our products are custom designed and manufactured but where appropriate we suggest the use of a standard design to minimise costs and lead times.
Dual laminate GRP combines the outstanding strength of GRP with the high chemical resistance of a thermoplastics inner shell. Design is not limited to available moulds or mandrels, custom sizes and shapes can be produced to suit the requirements of your application precisely.
Forbes are equipped to manufacture using a wide range of available thermoplastic inner shell materials allowing extreme operating conditions to be accommodated:
PP (polypropylene)(Celmar) is the material of choice for a vast range of applications. It has superb chemical resistance and a higher operating temperature than polyethylene. It is free from taint or toxicity, is highly cost-effective, and has gained widespread acceptance across many industries.
HDPE has in practice been superseded by PP for Dual Laminate construction. There is no price advantage and HDPE is mechanically inferior and less suitable for higher temperature applications.
UPVC (unplasticised polyvinyl chloride) is used in particular applications for its resistance to strong oxidising and reducing chemicals, especially chlorine based compounds.
PVDF (polyvinylidene fluoride) and ECTFE (ethylene and chloro-trifluoroethylene copolymer) are exceptionally high performance materials especially resistant to aggressive chemicals at higher temperatures.
We will always endeavour to recommend the most cost effective solution to your requirements.
All Forbes dual laminate 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 (glass fibre reinforced plastic) materials. It is a very thorough and stringent standard but DOES NOT cover any aspect of the manufacture of tanks in other materials such as metals or freestanding thermoplastics.
Forbes standard SDL range of tanks offer superb value for money. They are hand fabricated using GRP with any of the above thermoplastic inner shell materials
