Continuous development and innovation in the production of plastic pipes made by high density polyethylene (HDPE) has enabled the industry to produce much larger diameter systems than ever believed possible. The enablers for production of such large plastic pipes are three main pillars: continuous innovation of plastic piping raw materials with improved properties, advances in extruders and other equipment developments as well as value- added engineering. This has meant that plastic pipes have become the piping of choice for usage in industrial, municipal and infrastructure works, such as water distribution and transmission, storm water management and sewage.
Especially in the Middle East governments and industries have continued to invest, knowing that low labour costs and low feedstock and material costs, would ensure that they remained competitive. Also, many large water and wastewater projects have been continued for the desalination of sea water, wastewater treatment or water recycling, to provide improved water and sanitation for the growing population. All these projects require large diameter pipes and in many of these countries they have had the confidence to break with tradition and choose thermoplastic pipe materials rather than the conventional ones: such as steel, ductile iron or concrete.
