Large-Diameter Shield Tunnelling — China

CENTOR supplies tail sealant grease and complete TBM lubrication packages to some of the largest-diameter shield drives currently underway in China — spanning urban road tunnels, a national water diversion scheme, and a twin-bore metro crossing beneath the Yangtze. On every one of these projects the machines operate at the edge of their design envelope: high water pressure, hard and abrasive strata, and excavation diameters above 12 m.
