The threads of the rod and casing pipes, which are made of high quality cold drawn seamless pipes, are machined on CNC lathes.

Casing Pipes support the walls of the borehole and help us understand the tendency of unstable soils to collapse. Since loose soils such as sand, claystone and clay collapse easily, casing pipes are needed to prevent damage to well equipment. Another task is to prevent drilling fluid from entering the cracks.
