Bolted steel tanks from The Tasman Tank Co. offer several advantages to the end user in terms of speed of construction and installation, hygiene, cleanliness as well as zero discharge capabilities.
There is an ongoing debate about the best construction materials and technologies for big industrial tanks and municipal liquid storage tanks.
Large storage tanks and industrial process tanks are built to ensure hygiene for human consumption and cleanliness for high-tech industrial processes as well as support important industrial applications such as zero discharge processes.
Bolted steel tanks are suitable for such applications and can hold upwards of 10, 20 or even 30,000 tons of liquid according to Tasman Tanks, which builds more than 200 such structures a year in Australia and New Zealand.
Key advantages of bolted steel tanks over concrete tanks include non-leakage properties, cost-efficiency in construction and maintenance, longer life-span and their huge range of high-tech liners that will not react with the contents they protect.
A key advantage however, in bolted steel tanks is the speed of bolted construction that makes them highly suitable for installation in remote and climatically challenging areas.
Bolted site construction allows for control of all quality processes in good or bad weather. Speed of construction is also a major factor in markets such as mining and petroleum resources, where companies may want to get their projects off the ground at the earliest to generate ROI.
The basic needs of many applications can be cost-efficiently met by versatile bolted steel designs incorporating an internal membrane liner.
Wall sheet material from Tasman Tanks ranges from Galvabond and hot dip galvanised steel to stainless steel. Internal membrane liners include PVC, Aeon, butyl rubber, polypropylene or Strongline. Roofs, where required are designed to AS/NZS1170.2 and made from monoclad steel, long-life zinc-aluminium and aluminium.
Steel tank design is driven by the demands of technologies involving zero discharge applications, which are vital for major industries to meet their environmental and production imperatives.
These technically demanding but increasingly common applications involving vacuum and pressure requirements benefit from advanced coatings that can contain diverse liquids and will not impact the contents over time.
Bonded coating systems developed by Tank Connection group and Akzo Nobel are particularly suited to totally sealed applications where all the liquids involved in a process are retained on-site.
These applications can include digestion, methane capture, biogas capture, biological membrane reactor, anaerobic and aerobic processes, ultrafiltration as well as demineralised water.
Tanks designed for use in process systems include bulk storage tanks, intake tanks, flotation tanks, filtration tanks, mixing tanks, balance tanks, disinfection tanks, detention tanks and settling tanks among others.
Backed by their experience in delivering over 200 large steel tanks each year, Tasman Tanks recommends bonded coatings such as Tank Connection’s new generation proprietary LIQ Fusion 7000 FBE internal coatings.
Approved for potable drinking water with NSF-61 international standard approval, LIQ Fusion bonded coatings are highly suitable as bolted and welded tank linings.
Designed as a replacement for glass/porcelain enamel coatings, these tank coatings outperform earlier systems several times over with extended warranties on potable water storage. Performance with other industrial liquids and wastewater is excellent.
Independent engineering assessments for tank design and specifications are essential for companies to derive optimum performance and durability from their steel tanks.
Bolted steel tanks from Tasman Tanks are certified to all relevant codes, with independent engineers providing verification of specifications and performance.
Additionally, the company’s project management policies including quality management, environmental and OH&S systems are regularly reviewed by an external auditor to ensure adherence with government and industry regulations.
