RD® casings

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. 

Applications:

  • Drilling water and thermal wells
  • Steel core piles
  • Anchoring
  • Horizontal drilling solutions

RDc casing tubes

RDc casing tubes save up to 90% installation time

RDc casing tubes have been developed to drilled casing applications where reliable and especially effective splicing technology is the priority. By using threaded RDc splices during the casing installation it is possible to save up to 90% time compared to traditional splice welding (RDc splicing time approx. 1 – 2 minutes).

RDc casing tubes are delivered in 3 meter long elements. Both ends are threaded. The casing tube elements are based on longitudinally welded SSAB Domex Tube Double Grade (S355J2H/S420MH) steel pipe.
