Casing drift mandrels are mainly used to check whether the inner diameter of casing meets the requirements. It is a necessary procedure before downhole tools are run. The outer spiral guide groove of the casing drift mandrel facilitates chip removal and reduces fluid flow resistance. The length, outer diameter and buckle type of various specifications can be customized according to customer needs.
