Application

The casing are designed to perform cased holes. Especially for the construction
of bored piles by rotary drilling rigs the casing joints due to the machning accuracy
guarantee a fast placement and bolting of the casing as welll as best force transmisssion



Feature

Double-wallled casing can be used universally,as they are designed especiallly
for transmitting high rotational annd vertical forces as created by the ratary drives
and oscilllators. The use of double-walled casing ensures a flush drill string.
