"Premium" casing pipes


Employed in rotary drilling with fluid circulation in particularly difficult soil. Manufactured with cold-drawn seamless steel tubing with box/pin end threadings.
Heavy duty casing is also available where tubings have a greater thickness compared to the standard kind.
Penetration of the soil is obtained by using a casing shoe having tungsten carbide inserts or a diamond core bit.
