Australasian Corrosion Association Inc. NEW ZEALAND BRANCH DEC 2014 NEWSLETTER ACA AUCKLAND NOVEMBER MEETING REPORT On November 18th the Auckland Division members and guests were hosted by Sulco Pipelines Ltd to a meeting at Sulco’s premises in Manukau, to hear visiting international speaker Mr Gurinder Singh Sethis, Business Director India & Asia-Pacific, Sealforlife Industries. The title of Gurinder’s address was “Buried Pipeline Coatings – The Good, The Bad, and The Ugly”. After a social gathering, the presentation commenced with an introduction to pipeline coatings over the past 100 years, from bare steel and coal tar epoxy to sophisticated multilayer coatings. Modern pipeline coatings comprise three layers including a primer, an anti-corrosion mid-coat and an external polyolefin layer. A good pipeline coating system provides a high dielectric barrier, with good UV, chemical, moisture and heat resistance, along with good
adhesion and resistance to shear forces due to the soil when buried. It was then explained how the performance of a pipeline coating should be evaluated, properly installed and inspected before burial. Gurinder then covered aspects of corrosion and pipeline coating defects and he presented a number of case studies of coating failures in the pipeline industry. Finally Gurinder described the various Sealforlife pipeline coating systems available, including Polyken, Stopaq and Powercrete. The roles of each of these coating systems was outlined for the pipeline industry. Following a Q&A session the chairman of ACA Auckland Division, Wayne Thomson, thanked Gurinder and his colleagues for a very interesting talk. He also thanked the Sulco staff for putting on the joint meeting and inviting ACA members to attend.

Australasian Corrosion Association Inc. NEW ZEALAND BRANCH DEC 2014 NEWSLETTER ACA NEW PLYMOUTH IS UP AND RUNNING The next speaker was Neil Pain from Rosen who explained the different methods of measuring faults in pipelines with varying pig systems. Due to lower supply pressures from depleting wells, increasingly complex intelligent pig systems are required. New developments to adapt to this challenge include self-driven pigs. Lastly, Sean Ryder from Phoenix Solutions and Graeme Gummow from G² Consulting explained the effects of AC current on pipelines, and how associated corrosion mechanisms work. The presentation included some animated demonstrations of AC current from Graeme. The audience will forever associate the AC effects on pipelines with flying arms and dancing, possibly not out of place at an “AC/DC” concert! The ACA New Zealand branch has been actively promoting and supporting activities across New Zealand in 2014, not only in Auckland and Wellington but also Christchurch and New Plymouth. This has been manifested in the establishment in regular technical activities in Christchurch and the resurgence in activities in New Plymouth. The year ended with a successful technical meeting at the Snug Lounge in the centre of New Plymouth. The venue was indeed snug not only due to the name, but the fact that 40-odd keen corrosionists squeezed into the venue. This is fantastic news for the New Zealand Branch. The committee are motivated to ensure a successful 2016 ACA conference in New Zealand, and want to get the message out across the full length and breadth of New Zealand. With the Christchurch rebuild and with New Plymouth being the oil and gas centre of New Zealand, this is timely.
With the able direction of the night’s MC Jaco from Carboline, the speakers managed to answer several questions before the formalities finished on time. The majority of speakers and delegates stayed behind for some refreshments and fellowship. With the support of the night’s sponsors NZ Inspection Rentals, Carboline and the ACA, the evening could well and truly be considered a success. Importantly, the demand for regular events in 2015 was established and with the momentum generated thus far, the ACANZ New Plymouth Division is set to flourish!
The ACA centre assisted with arranging the speakers, venue, marketing and registrations. Attendees enjoyed three technical talks - firstly, Andrew Webb from Carboline / Altex Coatings spoke on the different coatings technologies and various testing regimes. This included a detailed explanation of how cathodic disbondment tests on coatings are performed. To: Ms Monika Ko, Treasurer, NZ Branch I wanted to thank you for the cheque for the AC Kennett Award for 2014 which arrived safely yesterday. It was a great honour (and surprise) to receive this award and I would appreciate it if you could pass on my thanks to the NZ Branch Office bearers. From when I first became involved in coatings for corrosion mitigation and the degradation of these materials, I became aware of the work of
Arthur Kennett since I used his book in some early consulting problems. I understand that it is still available today; a fitting testimony to his contributions. I am therefore doubly delighted that I have received this award that perpetuates his name . Yours sincerely, Graeme .

Website of the Month Long-line Corrosion
Recently ACA has focused on buried pipeline corrosion issues. Long-line current is a type of current that flows through the ground from a cathodic or anodic spot and goes back along pipelines or other types of metal structures, below the ground. The current can travel an extensive distance. It is similar to a stray current and can occur at extensive distances from the source of the electric current.
