RD casings

Made of longitudinally welded steel pipe, RD casings (RD140–RD270) are protective pipes installed by drilling.

The standard steel grade is S355J2H, and the high strength of RD casings together with sufficient wall thickness ensure a reliable end result, even in difficult drilling conditions.

RD casings are usually spliced by welding and all RD casings are highly weldable.

Applications:

Drilling water and thermal wells
Steel core piles
Anchors
