Designing Durable Steel Structures – SNZ TS 3404

With the publication of SNZ TS 3404 in 2018, its inclusion as an Acceptable Solution in the NZ Building Code in 2019, and the recent publication of the Engineering NZ B2(Durability) guidance; progress in providing design engineers with the technical guidance to design durable steel structures continues.

Dust Control in Construction

The second in a series of joint webinar presentations on Silicosis and its prevention, presented by ACRA and The ACA. The presentation gives the audience a view of how much dust normal operations of drilling, cutting and grinding concrete generate. It then covers the engineering controls available to manage dust emission and how you use these in conjunction with PPE to ensure operators/supervisors remain well below the required Silica dust levels.

Evolution of Coatings for Protection against CUI

The ACA Oil & Gas Technical Group invited our first international guest speaker, Neil Wilds (Sherwin Williams) to kick off a series of webinars focused on the challenges of detecting and mitigating CUI. Corrosion under insulation (CUI) is one of the major problems faced by asset managers throughout the oil and gas industry. Neil will be delivering a presentation on the evolution of coatings for protection against CUI, then taking questions from our attendees.

Balancing the Interactions of Concrete Demolition, Containment & Silicosis

The ACA and ACRA present the first in a series of joint webinar presentations on Silicosis and its prevention. The world as we know it is constantly changing. In the construction industry, often competing pressures of safety, environment and productivity are at the forefront of an engineers mind. Our first webinar in this series will explore these themes in the context of demolition, containment and silicosis in the concrete repair industry.

AEC & ACA VIC Branch – CP Seminar – The May Corrosion Spectacular

The Australian Electrolysis Committee and Victorian Branch of the ACA are pleased to host a joint meeting all about Cathodic Protection – The May Corrosion Spectacular! This webinar, which took the place of the annual electrolysis committee meeting and include the AGM, featured a diverse range of presentations covering CP rectifiers, data monitoring and much more.

Copper Based Antifoulings on Aluminium Marine Vessels

Antifouling coatings for aluminium vessels have been a controversial subject for many years and for many years the use of organo-tin based coatings was seen as the most effective long term option. Organo-tin products are no longer an option and this has resulted in evaluation of alternatives. Traditionally the use of copper based products (Cuprous Oxide mostly) had been an effective option for steel hulls but were avoided for aluminium due to concerns with the interaction between the Cuprous Oxide and aluminium hull.

Preparation for Windtower Coating Using a Bristleblaster

The ACA hosted a presentation and product demonstration from Phil Chester, Managing Director of Montipower. In this webinar, Phil presents some case studies covering recent and ongoing projects where the Bristle Blaster is being used specifically for wind tower repairs. This presentation included a demonstration of the correct use of the tool and an explanation of the difference between the Bristle Blaster and an often confused tool in the market. Whilst Phil primarily discusses wind tower maintenance, the principle of preparation for coating a wind tower is virtually the same as any steel preparation when it comes to using the Bristle Blaster.

Using Stainless Steel in a Marine Environment

Graham’s lecture focusses on the selection and use of stainless steel in seawater (especially in piping), the importance of correct procedures and practices in fabrication and the usefulness of Copper Nickel alloys.

Managing Corrosion Using Integrity Operating Windows

Unexpected corrosion damage is just as likely to arise from defective process control & lack of recognition of potential damage mechanisms, as incorrect alloy selection.

Operating plant is subject to variability of service condition arising from changes in feedstock, temporary process upsets, shutdowns for inspection and restart all representing a significant challenge to reliable operation.  Corrosion damage mechanisms may proceed intermittently or steadily and time to failure may range from seconds to years and consist of initiation and propagation phases.

Conservation of Cultural Heritage

Our island nations are littered with historic shipwrecks which have been recording the microenvironment of the oceans since 1622 off the Western Australian coast. A study of the layers of decay recorded on degraded metal objects provides climate and corrosion scientists with a unique insight into the changing conditions on the seabed and with data on seawater temperatures.

Working Through COVID 19 For the Corrosion Industry

The COVID-19 global health crisis has impacted all our lives to an extent not experienced this century. Our personal, family, social and vocational lives are all going through unprecedented change and the need for all of us to adapt and innovate has been forced upon us by one of the most significant market disruptions many of us have ever faced. While many of the challenges we face are universal, every industry, organisation and business is unique and the complications and opportunities that have arisen are varied. To explore how this crisis is affecting those within the corrosion mitigation industry, the ACA hosted an interactive webinar panel featuring a selection of guests speakers from different industry subsets representing Contractors, Asset Owners, Consultants, Coating Suppliers and Equipment Suppliers.
