摘要： A casing member for forming a connection between tubular sections. The member has heat shrinkable end portions (51a, 51b), for connecting on respective adjacent end surfaces of the tubular sections (13, 14) adjacent the joint (19), and a middle portion (51) for spanning between the end surfaces of the tubular sections (13, 14). The end portions (51a, 51b) are formed integrally with at least a portion of the middle portion (51) and have a zone that has a relatively small wall thickness while the middle portion (51) having a relatively large wall thickness. This member may be made by heat shrinking a sleeve on an inner core on a mandrel or by uniting opposed ends of a heat shrink sheet having one or more auxiliary layers bonded to it. The properties of the core or auxiliary layer or layers may be tailored to provide desired properties or capabilities.

摘要： A corrosion preventing factory or field applied coating has at least two discrete organic polymeric layers directly or indirectly united together. A first of said layers has a water vapour permeability of 0.005 to 10 g.mm/m /24h at 23 DEG C, 100 % RH. A second of said layers has an oxygen permeability of 0.01 to 10 cm .mm/m /24h.atm at 23 DEG C, 50 % RH, and/or a carbon dioxide permeability of 0.01 to 30 cm .mm/m /24h.atm at 23 DEG C, 50 % RH. In aggregate the coating has a water vapour transmission rate of 0.05 to 0.6g/m /24h at 23 DEG C, an oxygen transmission rate of 0.01 to 10 cm /m /24h.atm at 23 DEG C and/or a carbon dioxide transmission rate of 0.01 to 20 cm /m /24h.atm at 23 DEG C. These coatings can serve to greatly retard corrosion and in the case of the carbon dioxide barrier material greatly reduces stress corrosion cracking.
