UHMWPE is also used in the manufacture of hydraulic seals and bearings.
2.
Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly.
3.
To accomplish the double acting feature, additional hydraulic seals are added to internally seal off the individual stages.
4.
The plan is contingent on the replacement of a leaking steering thruster on Discovery as well a leaking hydraulic seal.
5.
The hydraulic seal occurs in rocks that have a significantly higher displacement pressure such that the pressure required for tension fracturing is actually lower than the pressure required for fluid displacement for example, in evaporites or very tight shales.
