A code of practice outlining the safety standards for design, installation and operation of polyethlyne piping in the coal seam gas indsutry has been made freely available with the help and support of PIPA.
An official call for papers to be delivered at PLASTIC PIPES XIX Conference and Exhibition has been issued by event organisers. Deadline for submission of abstracts is 31 October 2017. The Conference and Exhibition will take place in Las Vegas, US at the Red Rock Resort on the 24 - 26 September 2018.
Polyethylene remains the largest polymer resin used in the world today. The seminar, led by Qenos will explore polyethylene and downstream processes. It will cover an overview of the Australian market for extruded PE pipe and provide and understanding of polyethylene set up and design for optimal performance. Problem solving in heat sealing of PE films and printed technology for polyethylene film and pipe, will also be reviewed.
For decades, the Australian plastic pipe industry has played a key role in the provision of quality and sustainable pipe product for major water infrastructure projects serving the needs of rural and regional communities throughout Australia. This has included capping and piping the bores in the Artesian Basin. Other examples include the Wimmera Mallee Pipeline in Victoria, one of the most significant water infrastructure projects in Australian history.
Over the past five years, as the major CSG projects have moved from the design to the construction phase, and now into the production phase, there have been many significant advances and developments in equipment, materials, construction and testing procedures. This seminar and exhibition will provide an inner-CBD opportunity for industry members to see and hear how these techniques and procedures are maturing and developing.
‘Polyolefin sewer pipe systems have a service lifetime expectancy of at least 100 years.’ This is the conclusion of a recent two-year project commissioned by TEPPFA and independently scrutinised by Professor Heinz Dragaun from the Technical School for higher education (TGM) in Vienna. The project involved the excavation of many samples from in-service pipe networks that were tested and assessed under meticulous laboratory conditions.
In response to enquiries from our customers, Iplex has established a PVC pipe recycling facility at our Sydney factory.
As PVC pipe has an anticipated service life in excess of 100 years, research conducted by Iplex and the Plastics Industry Pipes Association of Australia has revealed very little waste PVC pipe product from demolition sites is finding its way to landfill. In the decades ahead, this situation may change but for now most PVC pipe entering the waste stream is short offcut pieces and surplus unused new product.
In conjunction with APIA, PIPA has developed a set of competency standards that define the range of engineering competencies required by the industry for plastics pipeline design, construction and operation. The APIA Pipeline Engineer Competency Standards define competency for pipeline engineers and provide a common industry framework for determining when a pipeline engineer has the expertise to undertake particular pipeline engineering roles. PIPA's POP Guidelines are referenced throughout the different competencies and these are freely available on this website.
At the last ISO TC 138 meeting which was held in Oslo 2013, the increasing importance of rehabilitation to the industry was identified with Subcommittee 8- Rehabilitation of Pipeline Systems, being formed. Originally a working group of the main committee, this subcommittee includes 4 working groups:-
Work has begun on Version 3 of this document. As many will know this document is now part of the Queensland Government regulatory framework governing the CSG industry in Queensland. Much of the activity in this revision centres on operational and commissioning procedures. In terms of pipe materials the PE100 systems are comprehensively covered and not in need of any significant change. There is increasing interest in specialised plastics pipe systems that can operate at higher temperatures and higher pressures to supplement the rapidly developing PE gathering network.
Hunter Water north of Sydney recently replaced an 85 year old 900mm diameter steel pipeline suppling water from the Chichester Dam to the Hunter Water distribution network. The old steel pipeline required continual maintenance and repair. It was also prone to flood damage and traversed an environmentally sensitive wetland.
The new pipeline crosses the Hunter River at Iron Bark Creek. This crossing is arguably the most difficult part of the pipeline project and it was this section under the river where PE100 pipe was used.
You may recall that the largest stock and domestic supply pipeline project in Australia was commissioned in 2010 and has been supplying the community of the Wimmera Mallee very successfully since that time. The project involved replacing 17,000km of wasteful open channels with around 9,000km of pressure pipeline. Something over 8,500km of this was plastics pipe -the majority being PVC and the rest PE. The plastics pipe was largely sourced from our two major manufacturers and key PIPA members Vinidex and Iplex.
Many people forget that PVC pipe and conduit has been around since 1960 in Australia. The origins of Vinidex and Iplex also date back to the early 60’s. Electrical conduits, then sewer pipes were made using PVC followed in the mid 60’s by pressure pipe. The regional infrastructure projects of Victoria and NSW were the first to take advantage of this great new pipe system. The gas industry also used PVC in WA, Victoria and NSW.
The Green Building Council of Australia (GBCA) announced on 15 January 2010 the outcome of their review of the PVC material credit in the Green Star Rating tool. The changes being introduced by the GBCA are the culmination of a long and rigorous review of PVC in the built environment.
PIPA Executive General Manager Mark Heathcote recently met with key staff from building industry organisations and government building and construction authorities to alert them to the changes to the Green Building Council Australia (GBCA) Green Star rating tool.
Best Environmental Practice (BEP) PVC pipe products are now available fully certified from four PIPA members – Iplex, Vinidex, Pipemakers and Australian Plastic Profiles. All three pipe manufacturers have been independently audited to confirm their products meet the GBCA BEP requirements.
