Method for Friction Welding Subsea Flowline Connectors |
| 摘要 |
Methods of rotary friction welding a (e.g., concentrically) threaded connector to a subsea-type riser or flowline pipe segment and/or of rotary friction welding cladded pipe segments. Subsea-type riser or flowline pipe segment with a (e.g., concentrically) threaded connector fused to the pipe segment at an autogeneous friction welded seam, and/or subsea-type riser or flowline cladded pipe segments fused together at a friction welded seam. |
