发明名称 PROCESS FOR SHEATHING A PLASTIC PIPE WITH A METAL SHEATH
摘要 <p>In a method for sheathing a plastic tube with a metal sheathing, a metallic band (20) is laid around a plastic tube (14), the metallic band (20) comprising longitudinal edges (32) bent to a common side thereof, which are, when the metallic band (20) is laid around the plastic tube (14), in abutment and extend substantially parallel to the longitudinal axis of the plastic tube (14) and are welded together. The volume of the bent longitudinal edges (32) and the welding energy are chosen such that the metallic band (20) welded together at its longitudinal edges comprises, in the region of the longitudinal seam (46), an outer surface (50) lying substantially within the outer peripheral surface (48) of the metal sheathing after welding.</p>
