Fibreglass and plastic lined fibreglass tanks can be made
Some of the largest tanks built to date include the following -
Settling cones have been manufactured to date up to 10 metres in diameter. These are usually supported on a steel ring beam. Internal v-notch weirs are installed that are fully adjustable once the vessel is installed and levelled on site. Where transport sizes become impractical, the vessel can be supplied in sections with final assembly taking place onsite.
Complete fibreglass mixer settler units have been manufactured for solvent extraction plants. The settlers are built in panels, bolted together on site and then joints finished off. The settlers include height adjustable weirs to ensure the liquid flow can be maintained at the correct heights. Special consideration is given to the design of the mixer boxes, which are subjected to large positive and negative forces around the bottom of the agitator.
Wherever possible all tanks are fully constructed in our workshops. Where this is not possible, tanks are sectionalised and a small amount of site work is completed upon final assembly on site. For extremely large tanks, various components of the tanks are constructed in the workshop then fully built on site. On site construction is completed in controlled conditions to ensure there is no contamination from other site activities or weather conditions.
All tanks manufactured by RGE Pty Ltd are fully designed in accordance with Australian, British or American standards. We do not have specific sized moulds that our clients need to be satisfied with. All moulds are purpose built for each project. Finite element analysis is completed where required to verify any aspects of design. Design drawings are produced using either AutoCAD or Microstation software.
As part of the design, the resin system and corrosion barrier requirements for the tank are determined. There are many resin and plastic types available giving improved service in different conditions. Selecting the appropriate materials is completed in-house or by the resin and plastic manufacturers. These suppliers will give written material selection advice when requested.
Variations to standard tanks can include the addition of agitators and baffles, cone bottoms, torispherical heads as well as ladders and handrails for trafficable areas. The tank can be circular, square or any other shape.
The external surface of tanks can be either a natural resin colour, translucent or be finished off with a pigmented gel coat. The gel coat provides the best resistance against UV degradation and weathering.
