Flush Joint Casing
Flush joint casing is used to close off zones of material which tend to cave into the exploration hole. The dimensions of the casing permit one size to fit into the next larger size. PennDrill Manufacturing also makes the HWT , PWT, and NWT threaded casing as well as the necessary drive heads.
