ExcelPlas Polymer Testing Laboratory for Polymer Pipe Testing
Materials characterization, failure analysis, quality control, and materials and process development services are offered to polymer pipe manufacturers, installers and end users.  Our analytical techniques allow us to assess elemental and chemical material composition, thermal properties, coating thickness, electrochemical properties, surface chemistry, surface wetting, corrosion rates and pitting potentials, contamination and degradation problems, metallography, fractography, phase transitions, static coefficient of friction, adhesive bonding strength and causes of adhesive bonding failures, surface tension and surface energy, tensile and compressive strength, bend deflection, elasticity properties, UV and visible light absorption and reflection, density and porosity, and many other material properties integral to improving your piping products.  We have conducted analyses on a broad range of materials processed in a multitude of ways and used in thousands of applications in many hundreds of environments.

Our capabilities give us many powerful tools to apply to your materials and process evaluations to enhance your product and productivity. We produce comprehensive written reports to ensure that you can fully understand and independently examine the analytical results and conclusions. This establishes a documented history for future process and product development and quality control issues.  It is usually a great idea to also characterize your materials when all appears fine as a baseline for comparison should any future problems with your materials or their processing occur.

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.
