RD® steel casing pipes

RD® steel casing pipes for reliable results under demanding conditions

Downloads

    RD® steel casing pipes (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. All RD® steel casing pipe sizes feature high weldability, enabling easy splicing.

    Applications:

    • Drilling water and thermal wells
    • Steel core piles
    • Anchoring
    • Horizontal drilling solutions
    RDc steel casing pipes save up to 90% installation time

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