Savcor Products Australia launch new compact and innovative galvanic anodes for concrete structures

Concrete repair in chloride contaminated structures causes incipient anode formation and results in reinforcement corrosion and concrete spalling at the border of repair areas. Performing the repair work using high resistivity concrete and installing galvanic anodes in the parent concrete at the edge of the repair patch can ensure targeted current delivery to the high-risk corrosion area in the concrete around the repaired locations.

Savcor Products Australia is launching the new anodes on to the Australian market. The compact, alkali-activated zinc anode is simple to install, is suitable for embedment within the concrete cover, and has 130 grams of zinc which provides long-term protection and excellent current distribution along the edge of the repair area.

Safeguarding Against Corrosion

Corrosion is one of the biggest issues faced by industries, businesses and governments in Australia, costing our economy over $30 billion each year, according to a report published by Curtin University.

Infrastructure, machinery and equipment affected by corrosion require ongoing maintenance and management to ensure safety, productivity and longevity. While there is a wide range of preventative methods available, the question is what is the right one for your business or asset?

Various paint and surface treatments can be used to protect different materials and surfaces by creating a barrier to prevent the transfer of electrochemical charge from the corrosive solution to the metal. However, depending on the environment and climate these can be ineffective and usually provide limited-term solutions.

Savcor Products Australia is one of the leading providers of corrosion prevention products in Australia, servicing a wide range of clients and industries including manufacturing, electronics, oil and gas refineries, waste water facilities, storage tanks, oil, gas and water pipelines, transport and logistics, concrete construction, civil works and infrastructure, military and marine.

New patented innovation: SPA discrete anode

Discrete anodes in concrete have been used extensively in reinforced concrete structures especially for concrete elements located in tidal and splash zones.

Due to their encapsulation within the concrete, discrete anodes eliminate the risk of grout acidification resultant from sea water in splash zones. These anodes are proven to be sound and highly effective for the corrosion prevention of reinforced concrete piles, beams and headstocks.

SPA 26 plus discrete Ti-Anode

A new state-of-the-art development from Savcor Products Australia improves and economises the installation process for discrete anodes in concrete. The new patented SPA 18 plus and SPA 26 plus anodes incorporate centralised spacers which centre the anode within the designated hole eliminating potential short circuits between the anode and re-bar by providing sufficient grout cover to encapsulate the ribbon mesh. This further eliminates the need for any down-the-hole covermeter testing and multiple drilling into the concrete to find the appropriate locations for installation.

All new SPA 18 plus and SPA 26 plus anodes will be supplied by Savcor Products Australia with the new spacers included at no additional cost. This patented invention will guarantee major reductions in the cost of corrosion prevention by eliminating multiple holes and unnecessary drilling into existing concrete and significantly reducing engineering time during site testing.

Vapour Phase Corrosion Emitters Explained

Vapour phase corrosion emitters are small, specialised devices designed to provide corrosion protection for metal components and parts which are enclosed in non-ventilated control boxes. The Vapour phase Corrosion Inhibitor (VpCI) emits vapours that form a monomolecular protective coating on internal metal surfaces. This coating protects critical, complex and expensive electronic equipment from corrosion initiation during operation, shipping or storage.

Three products from Cortec provide long term protection against corrosion in the presence of adverse conditions including salt, moisture, airborne contaminants, H2S, SO2, NH3, and others. These products all provide a similar level of protection.

VpCI-101 is a small patented device from which Vapour phase Corrosion Inhibitors are slowly released.
VpCI-105 & VpCI-111 are small patented plastic emitters with a breathable Tyvek® membrane through which corrosion inhibitors are slowly released.

Vapour Phase Corrosion Emitters - Easy To Install

VpCI emitters are simple and convenient to install. The devices should be installed at the earliest possible time, preferably during manufacturing or assembly.

To install, simply select a space within an enclosure where corrosion protection would be useful. Ensure that the surface to which the device will be affixed is clean and free of debris. Using the adhesive tape at the bottom of the device, affix the device to the clean surface.

For volumes greater than the emitter size, multiple devices may be used. If the enclosure is not totally airtight or if the access doors are opened frequently, replace the emitters more often than every 2 years. After periods of heavy maintenance replace the device.

Data Logging - CP Power Supply Unit

 

Data Logging Equipment

For CP systems in tidal zones, which is the case for most marine CP systems in Australia, it is essential to obtain accurate data for the potential measurement of reference electrodes under various tidal conditions to allow for accurate assessment and adjustment of the CP system. SPA’s system uses Agilent Data logging equipment which provides the latest and most reliable technology in data logging equipment.

Remote Monitoring Equipment

One of the most important requirements of a CP system is the continuous delivery of CP current to the structure. While it is required to undertake system testing and adjustment once every year in conjunction with the inspection of the structure, it is essential to ensure that current is being delivered at all times. SPA uses Agent G2 technology for the online monitoring of CP systems. The Agent G2 unit is heavy duty and reliable communication equipment which offers 24/7 access to the operating data of the system and includes an alarm function via email or SMS messaging.

SPA discrete anodes

State of the art technology for long term durability and performance excellence

The original concept for the discrete anode was developed some 20 years ago. Since then many types of discrete anodes have been installed in a large number of concrete structures around the world. Some of the issues with the earlier types of discrete anodes were related to the durability of the anode wire and the long term performance of the electrolyte surrounding the anode.

Discrete anodes are not suitable for all applications, especially for thin con- crete elements or where the reinforcement is randomly spaced within a structure. The main area of application of discrete anodes would be thick reinforced concrete elements such as beams, headstocks or piles in tidal/ splash zones where the application of ribbon anodes leads to grout acidification in most cases.

Having in mind the long term durability of the cathodic protection compo- nents installed permanently in concrete and the importance of delivering a CP system with low maintenance costs, SPA has developed a state of the art discrete anode which can be supplied at different lengths (from 100mm to 800mm) and provides excellent current distribution and allows for full encapsulation of the anode mesh by the grout material. SPA’s anode, if installed in a suitably size hole in the concrete and in conjunction with suitable cathodic protection grout, will provide the optimum solution for cathodic protection installations.

SPA’s anode is constructed using grade 1 Titanium conductor rods and conductor bars, Elgard/De Nora Titanium MMO ribbon mesh and is manufactured under strict quality assurance procedures. Each discrete anode has a
unique identification number and is tested individually to ensure full compliance to the specification.

Material Specification:

Anode Type:
Type 1 : SPA 26
Type 2 : SPA 18

Conductor Bars:
Titanium conductor bar tail / rod grade 1 Titanium in accordance to ASTM B265.

Current Rating:
Type 1 (4 ribs/3 ribs) 2.1mA / 1.575 mA per 100mm active length.
Type 2 (4 ribs/3 ribs) 1.4mA / 1.05 mA per 100mm active length.
