Iplex Discloses PB Pipe Issues to Market
Iplex® Australia has received a number of product quality complaints relating to a hot and cold water polybutylene pipe product it previously manufactured (under the name “Pro-fit”). The complaints relate to leaks in homes, primarily built by group home builders in Western Australia, which have caused repair or replacement of the pipes and, in some cases, damage to the affected homes. No legal proceeding has been commenced but the complaints directed at Iplex® Australia assert that the cause of the failures is attributable to it. Iplex® Australia has not identified the root cause or causes of the leak, including whether they are the consequence of pipe defect, building practises, local conditions or a combination of factors. The Group is also aware that the Western Australia building regulator (known as DMIRS) is undertaking its own investigation. Iplex® Australia’s exposure to costs incurred by the leaks, if any, will depend on the final determination as to their causes (or causes) and the extent to which it and/or third parties are responsible and any relevant insurance policies respond. Clarification of all these matters may take some time to be finally determined. There remains a risk the exposure of Iplex to these claims will be greater than the amount it has currently allowed.

The Hidden Hazards of PP-R & PEX Water Pipes and How to Avoid Them
PP-R and PEX pipes may become weaker over time, due to hot chlorinated water.
Also for PP-R, when installed using heat welding, can form weakened joints and internal beading. Both of which can require costly repairs later on. Ineffective PP-R installation can cause joint weakness and the internal beading caused by the melting of PP-R can encourage bacterial growth and restrict water flow.

ExcelPlas Labs Pipe Failure Investigations
ExcelPlas Labs have created a new benchmark in failure analysis of HDPE, PP-R, PB and PEX pipes in addition to PVC & CPVC pipes as well as composite GRP and GRE pipes. When a plastic pipeline fails to perform as intended, our team can determine the root cause of failure (e.g. oxidative failure, chemical failure, creep failure, over-stress failure, fatigue failure, design failure, etc). ExcelPlas are experienced with all plastic piping failure modes and mechanisms including Slow Crack Growth (SCG) Rapid Crack Propagation (RCP), Environmental Stress Crack Resistance (ESCR), Oxidative Stress Cracking (OSC), cyclic fatigue, manufacturing defects, and polymer material problems.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason. The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

ExcelPlas Poly Pipe Weld Inspection Lists Top 7 Causes of Weld Failure:
- Lack of scraping
- Inaccurate scraping
- Contamination from dirt, water, oil or clays
- Lack of Paralell-ness of fusion faces
- Misalignment of surfaces
- Time, temperature and pressure deviations
- Not adhering to cool times
We have extensive experience in inspection of poly pipe welds for assuring welded joint quality. Direct Poly Pipe Inspection ensures that operators are following the proven welding procedure; this reduces the occurrences of operational errors which lead to defects such as inclusions, lack of fusion (LoF), porosity and misalignment.
