Abstract
A coupling for joining two pipes, such as casing joints includes opposed ends having threads for engaging threaded ends of the respective pipes and a generally centrally located corrugated section, which provides the coupling with a degree of flexion in response to lateral stresses or loads.
Claims7
A coupling for connecting two pipe segments, each of the pipe segments including a pin end comprising a section having a threaded portion provided on an outer surface thereof, the coupling comprising:
- a generally tubular body having a bore extending there-through, an outer surface, an inner surface, and opposed first and second ends;
- and,
- a corrugated section located between the first and second ends;
- the inner surface of each of the first and second ends including a threaded portion adapted to engage the threaded portion of a corresponding pin end of a pipe segment;
- the corrugated section being adapted to accommodate transverse deflection while maintaining torsional, compression/tension and pressure performance characteristics of the base pipe segments.
