ABSTRACT OF THE DISCLOSURE: The propagation of cracks in a gasline is inhibited by surrounding portions of the gasline spaced along the length thereof by a strengthening element without inducing compression stresses in the pipe wall. This strengthening element is such that in each surrounded portion of the gasline the following relationship applies, Image where Cva is the Charpy energy per unit area measured transversely of the unstrengthened gasline and Cveq is the equivalent Charpy energy per unit area of the strengthened portions of the gasline and represents the sum of the Charpy energy per unit area (measured transversely) of the portion of the gasline and the Charpy energy per unit area of the strengthening element surrounding the portion. It has been unexpectedly found that when this relationship is met, a crack propagating with a constant speed of 300 m/sec. or less along the gasline stops within a distance of one metre after reaching the strengthened portion.
