Abstract: Provided herein is a wraparound closure sleeve for environmentally sealing conduits employing a heat-recoverable sheet oriented to shrink in the direction of its width, a first strip of self-amalgamating material disposed along or near one edge of the sheet and perpendicular to the direction of orientation, a mastic or hot-melt adhesive coated on the remaining surface area of the sheet, a second self amalgamating strip disposed parallel to the first strip on the opposite surface of the sheet where wrapping the sheet around the conduit, juxtaposing the strips and pressing them together forms a lap bond having sufficient lap shear strength to resist the hoop stress force generated by shrinking of the oriented sheet around the conduit and the mastic/adhesive is pressed and flows between the conduit and sheet.

Abstract: Process for the formation in situ of a tight coating of pores containing material between a hydrocarbon conveying pipe and a protecting envelope surrounding the same, said material being expansible by contact with the conveyed hydrocarbon so as to obstruct any perforation accidentally occurring in the pipe wall, said process comprising covering the pipe with a sheath of said expansible material containing a curing agent and a porophoric agent, placing the envelope around the pipe and heating the sheath by circulation of a heating fluid so as to produce simultaneously the curing of the sheath and the formation of pores therein by expansion of the sheath in the annular space provided between the pipe and the envelope.

Abstract: A method of manufacturing tubular articles wherein the open ends of a pari of elongated tubular members are closed by corrosion resistant inserts having flange portions overlying the radial end faces of the tubular members. The members are then aligned and surrounded by an insulating jacket provided with radially inwardly extending circumferential beads which abut against and are sealed to the respective flange portions of the inserts so as to fixedly secure the latter in the open ends, whereafter the jacket is severed between the beads thereof.

Abstract: A heat recoverable sleeve is disclosed which is capable of being installed on a longitudinal member without access to a free end. The sleeve comprises a flexible sheet of heat recoverable material having edges which may be overlapped and which have been coated with a contact adhesive. Chloroprene based contact adhesives are disclosed. The coated sheet is wrapped about the longitudinal member and the edges of the sheet are caused to adhere together by the contact cement. In order to prevent the overlapping edge from peeling back during recovery and opening the joint, a restraining member such as a sheet of metallic foil may be adhered to the overlapping edge and the region of the sleeve adjoining the underlapping edge. Alternatively, peeling back may be prevented by cross-linking the overlapping edge. Heating of the sleeve causes it to shrink onto the longitudinal member to form a secure closure.

Abstract: An improved seal for connecting liquid metal conduit sections. It comprises at least two rings made of fire-proof fibers, squeezed between the adjacent sections, with sealing means being provided between the rings in order to prevent leakage and cause the hardening or freezing of liquid metal which tends to seep between the two rings on the one hand, or between the rings and the adjacent conduit sections on the other hand. The invention can be used for very corrosive metals such as zinc and aluminum.
