Our aim at West Coast Poly is the selection of the most cost effective long-term solution to your storage requirements and without the right information we can't do our job properly. In industrial applications additional hazards can arise that would not normally be encountered with rainwater storage, the items listed below are for guidance only;
U V Resistance West Coast Poly tanks are manufactured to cope with the harsh West Australian environment and are suitable for external installation. West Coast Poly has adopted the new Cotene UV16 resin system as standard for its storage tank range so that customers can be assured they are getting the highest UV protection available.
Temperature The properties of polyethylene are affected by temperature and special consideration needs to be given where the tank is to be subjected to liquid temperatures above 35 deg C or below minus 20 deg C. The external air temperature is generally not as important as the temperature of the liquid being stored, however your supplier should be made aware if the tank is to be subjected to temperatures other than ambient.
Pressure or Vacuum Tanks are typically manufactured for hydrostatic loading only and should not be subjected to pressure or vacuum.
Specific Gravity (SG) of liquid Tanks are typically manufactured for liquids weighing no more than 1 kg per litre ( SG 1.0), if heavy liquids like dissolved fertilizers, brine solutions, etc are contemplated then greater wall thickness must be used.
Installation Environment Tanks are generally designed for external installation at ground level in a non-hazardous environment. They must be fully supported across their entire base area, (refer separate installation sheet for details). If your tank is to be inside or close to a building, elevated above ground level, partially or totally buried, located in a traffic area or in any other situation, which increases the level of hazard, you should advise us so that an additional safety factor can be applied.
Additional Hazards Areas of high wind, cyclone susceptibility or seismic activity are the most common additional hazards, however, flooding, soil subsidence, feral animals, caustic cleaning solutions and many other factors can play a part. You are the best judge of the hazards in your environment, so please inform us, "we can't provide for something we don't know about".
