Abstract
A process for manufacturing high-pressure tanks of low weight with an armored corrugated metal sheath, a corrugated pipe is circumferentially armored, with the metallic tank being introduced into the armored corrugated pipe. An assembly which includes the armored pipe and the tank is longitudinally armored except for oppositely disposed openings of the pipe and the metallic tank. The material of the metallic tank is caused to creep through plastic deformation under an effect of an internal pressure in order to obtain a corrugation of the cylindrical part of the metallic tank.
