Rotary Casing Pipe is obtained by driving a steel soding into the ground in order to protect the whole drilling operation; Basically, the rotary drilling tool during the working process, performs inside a mechanical protection made by the casing fixed into the ground.
Double wall rotary casing pipe can be used universally, as they are designed especially for transmitting high rotational and vertical forces as created by the rig rotary drives or oscillations.The use of double wall casings ensures a flush drill string.
Single wall rotary casing pipe can be used for applications where weight reduction is important.
