TUBI Reports $4.7 Million Loss for the Year 30 June 2020 (compared with 30 June 2019: Profit of $1.5 million)
During the first half of the year the Group completed the building, commissioning, and delivery of a Mobile Plant to Iplex Pipelines NZ Limited. The decline in investment activity in the upstream oil and gas industry, caused by the decline in oil prices, led to exclusivity restrictions and a reduction in orders, selling prices and margins. The Group also incurred significant operating costs in 1H FY20 due to a series of operator failings, resulting in approximately six weeks of lost production.

Law Firm Commissioned to Check Cancer Risk from ABS, PVC and CPVC Pipes Containing Titanium Dioxide
The Plastic Pipe and Fittings Association (PPFA) recently commissioned the law firm of Keller and Heckman LLP (K&H) to develop and coordinate testing on acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC) and chlorinated PVC (CPVC) pipes for the purpose of supporting their members efforts to comply with California’s Proposition 65 warning requirements.
At PPFA’s direction, K&H coordinated screening-level air-sample testing to determine whether the ABS, PVC and CPVC pipes included in the test emitted or generated airborne and respirable particles of TiO₂ or carbon black when cut by various power tools under conditions similar to the typical installation process for such pipes. As expected, the test results did not reveal airborne, unbound particles of carbon black or TiO2 of respirable size.

Testing and Compliance of Thermoplastic and GFRP Pipes
ExcelPlas has a wide experience in the field of plastic pipes and helps to detect failure causes in the behaviour of pipes in service and to prepare technical sheets both of a finished product and a raw material.
The ExcelPlas Laboratory has developed a series of procedures to identify failure and breakage causes that can appear during the use of structures designed with plastic pipes, corrugated pipes and/or GFRP, combining both analysis and tests on the material and the pipe as well as the knowledge acquired from the point of view of pipe installation. We check that the requirements are met following the standards EN 1796, EN 16422 and EN 13476-6, among many others. Some of the tests in which we are specialised are:
* Identification of polymer materials by DSC and FTIR
* Determination of the degree of curing by DSC
* Stress-strain tests: tensile, flexural and rigidity, with testing equipment up to 250kN.
* Circumferential rigidity and geometric control
* Calculation of densities and k values.
* Resistance to hydrostatic pressure
* Failure cause analysis
Oxidative Resistance Testing of Plastic Pipes
ExcelPlas’ Advanced Pipe Test Facility (APTF) has introduced new oxidative resistance testing capacity, providing the unique ability to quickly and effectively measure and evaluate material performance over time. Our capabilities include accelerated testing of the potential impact of disinfectants (chlorine, chlorine dioxide, chloramines) on the long-term performance of materials in potable water applications (most commonly PE, PEX, PE-RT and PP-R) as well as proprietary testing methodologies and leading edge proprietary analysis methodologies.
We currently test to:
• ASTM F2023 – Standard Test Method for Evaluating the Oxidative Resistance of Crosslinked Polyethylene (PEX) Tubing and Systems to Hot Chlorinated Water
• ASTM F2263 – Standard Test Method for Evaluating the Oxidative Resistance of Polyethylene (PE) Pipe to Chlorinated Water

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.
