METHOD FOR PRODUCING A LEAK-TIGHT VESSEL, AND A LEAK TIGHT VESSEL

摘要

The invention relates to a method for producing a leak-tight vessel comprising the steps of: - assembling an at least partly removable mandrel; - mounting an end fitting to the mandrel, the end fitting having an opening large enough to allow passage of the at least partly removable mandrel after disassembly; forming a shell layer by filament winding over the mandrel and over the end fitting; applying a gas and/or liquid tight layer to an inner surface of the shell layer; disassembling and removing at least part of the mandrel, while leaving the first end fitting in the shell layer. The invention also relates to such a leak-tight vessel.
