China's Hebei Chinaust Plastics has commissioned a production line for up to 3.5-m diameter polypropylene spiral wound pipes delivered by Bauku (Wiehl, Germany). A similar line had previously been delivered to Union Pipes Industry (Abu Dhabi).
"Water is a global issue, with the world facing major challenges to secure clean drinking water and get it to where people need it," said Wim Roels, resin supplier Borouge's CEO who was speaking to PlasticsToday at the recent Chinaplas show. "This is particularly so given the emergence of mega-cities, where water treatment is also a major issue." One potential solution for discharge of treated sewage to the sea is to employ massive spiral-wound pipe sections that are butt-welded together into overall lengths of the order of 2 km.
Similar spiral wound pipes have already been employed at the Takreer refinery in Abu Dhabi as well as Borouge's own polyolefin production facility in Ruwais, Abu Dhabi. In the past the sea water intake and outfall pipes would be constructed of glass fiber-reinforced thermoset plastic or concrete.
