Throughout the financial crisis in the West, governments and businesses in the Middle East and Asia have continued to invest in industry confident that low labour costs or low feedstock and mineral costs would ensure that they remained competitive. Also many large water and wastewater projects have been continued, whether this has been for the desalination of sea water, wastewater treatment or water recycling, in order to provide improved water and sanitation for their growing populations. All these projects require large diameter pipes and in many of these countries they have had the confidence to break with tradition and choose plastic pipe materials rather that steel, concrete or GRP.
Even though the financial value of the piping used in these industrial complexes is only about 10 -15 % of the total project cost it is important that the right materials choice is made, because the consequences of failure can be very high. For example if the cooling water pipes to a large petrochemical fail this can close the plant for several weeks, losing the company many millions of dollars. Experience has shown that the corrosion, abrasion and structural breakdown seen in traditional pipes are mu
PO pipes now have a successful 50 years history and continuous innovation of raw materials, manufacturing equipment and processes mean that PE pressure pipes up to 2,500 mm diameter and PE or PP non pressure pipes up to 4,000 mm diameter can be produced and have earned the trust of design consultants. In this paper the authors address the advantages and technical challenges of manufacturing and installing these large diameter PO pipes. This will be illustrated by the experience gained in a number of recent industrial and infrastructure projects across the Middle East and Asia.
