Services
Global Tanks provides a wide variety of services associated with maintenance, repairs, refurbishments as well as custom design.
Internal Inspection
An inspection of existing water tanks should be performed once every two years in order to identify and prevent potential future issues.
Global Tanks can provide inspections by fully-insured commercial divers, without emptying the tank.
Divers will look in particular for:
- Internal corrosion, including around the roof and support members
- Debris that could inhibit proper function – a critical factor for fire protection tanks
- Deceased wildlife
The ground, pipework and fittings will also be inspected, and video footage of inspections can be provided. Sampling for water acidity can also be performed.
Divers hold the latest Job Safety AnalysisJAS and Occupational Health & SafetyOH&S documentation.
Repairs and Retro-fits, Liner Replacement
We can undertake repairs and retro-fits to existing tanks, such as fitting new liners, level gauges, or installing access hatches, ladders and platforms that are compliant to new Australian Standards.
Large Diameter Tank extended life roofs and refurbishments
Global Tank’s has experience in design, construction and refurbishment of large diameter tank roofs and roof support structures to give an 25year+ service life.
In 2010, Global Tanks teamed with Barden-Steeldeck Industries to refurbish the 30 year old 74m diameter Sydenham Water Tank and 62m diameter Cowies Hill 1 Water Tank for Water Resources Alliance for Melbourne Water. Our contract involved the demolition of existing structure and design and construction of a 100% stainless steel roof support structure with Kalzip Aluminium roof.
Global Tank again teamed with Barden-Steeldeck Industries in 2009 to design, fabricate and erect the roof on the main water storage tank which is 70m in diameter. The roof structure require the fabrication and supply of approximately sixty 150SHS stainless steel columns sitting within the tank, which support galvanised roof beams and purlins and Kalzip Aluminium roof system.
Maintenance
Global Tanks can provide customers with a recommended maintenance schedule, or in the case of fire tanks, a schedule for the purpose of compliance with Australian Standards. This includes the yearly visual inspection and three-yearly service by competent and experienced personnel.
Plumbing, pipework & pumps
Global Tanks will design and fabricate a tank’s pipework and pump requirements in order to provide a turn-key tank system; one that is able to simply and easily integrate into an existing or new plumbing system.
Footings & foundations
Our expertise also covers the installation of appropriate tank foundations in full compliance with relevant Australian Standards.
Custom design
Global Tanks’ design capabilities extend far beyond just tanks. By designing and fabricating our own sundry parts, we can offer not only complete solutions, but customised ones.
Customisations include extra ancillary parts such as:
- Ladders – internal & external
- Stairs
- Platforms and walkways
- Hatches
- Landings
- Handrail systems
- Anti-vortex plates
- Internal and external coatings
- Vermin proof roof flashings
Our portfolio also includes machinery and architectural structural members.
Of particular distinction is our ability to tailor chilled water stratification tank diffusers; a challenging task in fluid dynamics requiring precision-dimensioning to suit the application’s parameters, such as charge/discharge flow rates and incoming/outgoing water temperatures. This design capability makes Global Tanks unique in our industry.
