Acoustic Testing of Plastic Pipe and Construction Materials

Plastic Pipes Conference Association # 2010 Vancouver

Ali Ahmadnia, Peter Allan, Rob Withnall, and Jack Silver

The acoustic properties of polypropylene, polyethylene and PVC which are widely used in the automotive, construction and pipe industries were measured. The acoustical parameter selected for this study is ‘sound transmission loss’. Acoustic tests were conducted using a Bruel & Kjaer acoustic tube with four microphones installed to determine sound transmission loss (STL) data from a 100mm diameter test piece. This method in comparison with the existing STL standards is less costly and requires less space and time. This work has been carried out in collaboration with the manufacturer of the acoustic test equipment (Bruel & Kjaer) to assess the possibility of developing a recognised standard for this test. Keywords : Sound transmission loss. Acoustic testing. Polymers.

Reinforced thermoplastic pipes (RTPs) are multilayer structured pipes reinforced with high-strength materials such as fibers (glass, aramid, or carbon fibers). RTPs are used to transport highly corrosive mediums at elevated pressures and temperatures. An example of that is the use of RTP in the Oil & Gas industry to...

Seismically active faults pose a risk to buried water pipelines that can be complicated to quantify. Fault type, slip rate, pipeline geometry, and soil conditions all factor into a complex soil-pipeline interaction. For critical pipelines that cross faults, high-density polyethylene (HDPE) has become an attractive...
