The casing tube is manufactured in tapered joint with modified buttress threadform.

The casing tube is manufacturedfrom alloy tubes and is a high strength product commonly used in geotechnicaland hammering operations.

The drill rods must be pre-torqued with the minimum recommended make-up torque topreload the box and pin prior to drilling.Drilling torque alone will not make-up the joint. The drilling operation torque should neverexceed make-up torque.
The casing tube is used to drill with the casing shoes and protect the holestones. It can also be used for thebroken formation stones.
