Elastomer tanks meet challenges of liquid storage

Supplier: Air Springs Supply
27 November, 2014

Globally proven Pronal elastomer and plastomer flexible tanks from Air Springs Supply are engineered to provide a solution to liquid storage and transporting challenges facing users onshore, offshore and in remote, inhospitable and emergency locations.

The enormously strong Pronal tanks – fabricated by the company that provided the lifting bags to raise parts of the ocean liner Titanic 4km down in the Atlantic – are suitable for uses ranging from civil and military organisations through to mining and energy, oil and gas, manufacturing and materials handling and construction and infrastructure groups.

Pronal tanks are available in capacities up to 1000m3 in several product ranges for air, sea and ground storage and for transportation of fluids in addition to water, including hydrocarbons, foodstuffs and agricultural and industrial products and waste,

The technology is simple, quick to deploy and cost-effective, says Air Springs Supply National Sales and Marketing Manager James Maslin, with scores of uses extending from buffer water tanks for civil and military potabilisation systems, through to transportable emergency water containers or fuel tanks for electricity generators and plant machinery on construction, exploration and development sites.

Pronal flexible tanks complement Air Springs Supply's established ranges of Pronal pipeline stoppers used by major Australasian companies concerned about spills of potentially hazardous or harmful liquids, as well as pipeline stoppers used for maintenance, testing and emergency tasks involving worker safety and environmental protection. Pronal products also include tough, compact lifting cushions.

The flexible tanks' design ensures liquids stored are never in contact with air, says Maslin. This permits safe storage of liquids such as paint, latex, fruit juice, emulsions and fuels. In addition, Pronal supplies all complementary products used in fuel logistics, including pumps, guns and filtering systems.

The quality and durability of Pronal water tank technology is relied upon by industrial, civil and military organisations around the world, including in remote, inhospitable and emergency situations.

Water uses include:

  • Potable water
  • Storm water
  • Grey water
  • Fire protection
  • Agriculture and viticulture
  • Civil defence and public works
  • Sewage in remote locations, using Pronal Green Tank technology

Structured tanks and ferry fuel tanks for aircraft, with anti-crash and self-sealing versions

In addition to stock products, Pronal can often provide made-to-measure solutions to specific requirements or in response to descriptions of particular needs.

Pronal products are based on more than 40 years of producing specialist pneumatic elastomer designs for demanding applications, including government, military, heavy industrial, emergency service, sub-sea and exploration.

Australian distributor Air Springs Supply also has more than 30 years' specialist experience in applying pneumatic actuation and isolation technologies.

The big advantages of the technology also include simplicity, portability and re-use. Maintenance staffs don't need huge amounts of gear on-site and Pronal products are easy to transport around plants to remote locations, where they can be used, moved on, and used again and again.
