National Oilwell Varco (NOV) introduced the Scorpion connector to its XL Systems portfolio of large-bore casing and conductor connectors. Deep onshore wells and shallow-water offshore wells demand robust connector strength and proven sealability in a cost-efficient connector design. Scorpion weld-on connectors deliver these requirements with full pipe-body strength and American Petroleum Institute (API) 5C5 CAL I sealability in a compact profile. Advanced finite-element analysis and full-scale physical testing have demonstrated that the connector’s tension, compression, and bending capacities meet full pipe-body strength. Combined loading sealability tests following API 5C5 show that the connectors seal liquid pressure for the full pipe-body internal-pressure and external-pressure envelopes. The connector design incorporates performance features found in other XL Systems large-bore premium connectors, including tapered threads for a deep stab, integral self-aligning stabbing guides, a hooked threadform, and a replaceable elastomeric O-ring pressure seal. The connectors are available in 16- to 30-in. sizes suitable for onshore and offshore conductor and surface-casing applications.
