Vesconite Hilube bushings, which were installed on the control arm linkages on the radial deep sluice gates on a hydropower dam on the Nile River, are still operating some seven years after a complete overhaul of the systems controlling water flow in 2013.
A company representative reports that the sourcing and specifying of components, including the no-swell self-greasing high-load-bearing bushings, were part of the turnkey scope of work performed by the company, which was responsible for all electrical, mechanical, and hydraulic aspects of the project.
工程公司订购了4米250毫米（外径）和190毫米（内径）vesconite Hilube空心条，以及2012年10月的225 mm（外径）和170毫米（内径）空心酒吧。
然后，工程公司及其承包商将衬套加工到所需的尺寸，然后将衬套调发，以及大坝盖茨所需的其他部件和设备到尼罗河项目。
在五个9.5米控制臂上安装了八个衬套，将液压缸连接到用于控制尼罗河沿着这部分水流的坝闸。
它们必须每臂携带80吨，但由于需要两种安全系数，因此指定每个衬套必须设计为160吨。
合同在两年内完成签署，其中一年分配给制造，一个月分配用于安装五个盖茨，包括衬套。
The company explained that the linkage arms connect the sluice gates to the hydraulic cylinder.
水闸栅极可以用尼罗河上的水降低或升高，以允许大坝的最佳水量，否则如果洪水无法充分控制，则会遭到破坏。
The project manager had intended to visit the installation in 2020 to inspect the gates and the bushings, with a site cover on each bushing removed during the inspection.
The project manager is satisfied with the relatively-maintenance-free solution with a high degree of redundancy that his company was able to provide the country authorities.
This large-scale project involved the installation of 275t of equipment, the co-ordination of suppliers from various countries, and challenging climatic and logistic constraints.
