Bushmans design and manufacture your tank to give you long, trouble-free service. While our tanks are extremely durable, improper handling and installation can result in damage to the tank, fittings, and accessories. Failure to comply with handling and installation instructions will void all warranties.
Upon delivery, inspect your tank immediately for defects or shipping damage. Any discrepancies, or product problems, should be noted on the driver’s delivery receipt book.
When unloading your tank from the delivery truck, avoid its contact with sharp objects. Forklift blades can cause significant damage if proper precautions are not taken. Do not allow tanks to be rolled over on the fittings. Large storage tanks, whenever possible, should be removed from truck bed by use of a crane or other suitable lifting device. (Lifting device is at purchaser’s expense) Keep unloading area free of rocks, sharp objects, and other materials that could damage the tank. If tank is unloaded on its side, carefully brace to prevent rolling so external fittings are not damaged.
Support the bottom of tank firmly and completely. Concrete pads provide the best foundation, and are recommended for industrial tanks. Prepare a reinforced concrete pad that is level and greater than the diameter of tank. Remember that 22,000litres of water weighs 22 tonnes, while 22,000Litres of molasses weighs about 31.5 tonnes.
However, in the event you deem that the base loading bearing factors are not important, prepare a ring on the ground greater than the diameter of the tank so that no part of the tank is bearing on the ring edge. Fill is to be consolidated with 50–75 mm of sand or crusher dust on top surface. You must maintain the consolidated fill in good condition during the service life of the tank. Place the tank onto the prepared pad. (If positioning requires a crane, this must be at purchaser’s expense)
Steel support stands concentrate the loaded tank weight onto the stand leg pads. It is recommended that stands be mounted on a concrete base. Bolting of stands is necessary to prevent movement due to agitation, wind, seismic loads and accidental contact. It is the purchaser’s responsibility to ensure that support structure is designed adequately for the purpose.
Do not mount heavy equipment on top of the tank. Fully support pipes and valves, so there is no external weight loading on the tank.
DO not rigidly pipe tanks. Use expansion joints to prevent damage at fittings from the differential expansion and contraction of the piping and tanks.
Tanks are designed for use only in the atmospheric storage of chemicals, never for vacuum or pressure applications.
Refer to the Bushmans capability chart (Chemical Resistance Chart) as a guide to suitable chemicals to store in your tank. Be certain tank, fittings, and gasket material are compatible with chemicals at ambient operating temperatures. Contact our support staff for information on chemicals not listed, or when uncertain conditions exist.
Confined spaces must be considered hazardous. Do not enter tank without first taking proper precautions.
Tank sizes as listed are nominal and calibrated gauges, when supplied on moulded tanks provide an indication of volume. Polyethylene tanks expand and contract which will affect volume. The degree in which this occurs depends on the size of the tanks, wall thickness, specific gravity (or relative density) of contents, temperature of contents and ambient temperatures.
WARNING: It is the installers responsibility to follow all appropriate Worksafe, OH&S and government safety regulations. The above information has been provided as guidelines for tank use and installation. It does not address safety issues which may be present at specific tank installation sites. Use appropriate safety practices when handling any tank and/or using heavy equipment.
