RD® casings for reliable results under demanding conditions
RD® casings (RD140–RD270), made of longitudinally welded steel pipe, are protective pipes installed by drilling. The standard steel grade is S355J2H. The high strength of RD® casings together with sufficient wall thickness ensures a reliable result even under difficult drilling conditions. When RD® casings are spliced by welding all RD® casings feature high weldability.
