The casing is designed to perform cased holes, especially for the construction of bored piles by rotary drilling rigs. The casing joints with high machining accuracy guarantee a fast replacement and bolting of the casings as well as the best force transmission effect.
We offer two types of casings:
Double-walled casings
Single-walled casings
Double-walled casings can be used universally, as they are designed especially for transmitting high rotational and vertical forces as created by the rotary drives and oscillators. The use of double-walled casings ensures a flush drilling string.
