Process of Drilling - All Star Training

Drilling fluid is pumped down through the hollow drill pipe using a centrifugal pump (mud pump) to a drill bit. The flud flows upward in the annular space between the drill pipe and the borehole to the surface where it is channeled into a settling pit and most of the cuttings drop out. Fluid from the settling pit overflows into a second pit ...

NEC Class 2 Power Circuits and Power Supplies

The NEC (National Electrical Code) is a North American standard, which can be regarded as a law in most of the North American states. Among others, the NEC describes the installation of electric conductors and equipment within or on buildings. The NEC also is the source of the Class 2 circuit definition, which limits the max. voltage and current.
