ABSTRACT:
Mechanical pipe joints and methods of forming same, wherein pipe ends are first prestrained into expanded bell and expanded pin shapes and then again strained by interference joining, both prestraining and subsequent straining being under controlled conditions which take maximum advantage of the metallurgical and physical properties of the materials to provide improved connection strength produced through approaching the ultimate strength of the material. Strain aging prior to joining may be used to further enhance connection strength to a point which requires exceeding the ultimate strength of the parent material.
