一项在西非大草原建立一个蔗糖基地的计划中,增强塑料管道充当了重要角色。这项计划包括在分散的150平方公里区域内7000公顷可耕地上,使用100公里长的地下管道为各块耕地引水,与这项计划竞争的有常PVC涂层的钢和铸铁管道。澳大利亚的Durit—Werke kerm公司以其可用性,价格低,短期长期工作均适宜等特点,再加之易于装卸运输,使其赢得了这项计划。迄今为止,这家公司为此项计划提供铺设的几种管道直径范围为200—1000mm。 One plan to build a sugar crop in the West African prairies is to reinforce plastics pipelines. The plan includes 7000 hectares of arable land in a dispersed 150-square-kilometer area, 100-kilometer-long underground pipelines for plots of cultivated land, and PVC-coated steel and cast iron pipe that compete with this program. Durit-Werke Kerm in Australia has won the program for its ease of handling, thanks to its availability, low prices and short-term long-term job suitability. To date, the company has several pipeline diameters ranging from 200 to 1000 mm laid for this program.
