Abstract

An original methodology was designed by Gaz de France R&D and its subsidiary DEGAZ for the evaluation of permeability on real pipes and assemblies directly at the operating temperatures and pressures. For this purpose, a design of experiments was elaborated to evaluate the sensitivity of the results to the major parameters for some representative polyethylene (PE) copolymers. Among these parameters, the through-wall distribution of crystalline lamellae was particularly focused on by means of Differential Scanning Calorimetry measurements. The PE under study could be roughly separated in two families with respect to their permeability. Even if these trends have to be consolidated, the results were in good agreement with the respective through-wall crystallinity (both level and arrangement) of the pipe specimens. The maximum calculated amount of methane diffused through a 1 km long pipeline in 1 yr under a 4-bar operating pressure is the order of the values announced formerly meaning <1 cu m/km/bar/yr CH4. This is an abstract of a paper presented at the 2004 International Gas Research Conference (Vancouver, British Columbia, Canada 11/1-4/2004).
