Group 11 element Parkes process. These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver
Conductor pipe and is a key structural foundation for the subsea wellhead. When drilling an offshore well, a marine riser is connected to the well, and this is subjected to large environmental forces such as current and waves which are transferred to the conductor. The forces can be large and also cyclical which can potentially cause fatigue damage to the conductor, especially in harsh environmental conditions. A Conductor tensioner unit (CTU) can be used in shallow water on jackup rig to withstand such damaging forces. Conductor pipe The Conductor Pipe is a large diameter pipe that is set into the ground to
