Abstract: A monotube steam generator, the pressure element or elements of which are comprised of tube of partially flattened section, enclosed within mainly close fitting substantially solid metal encasements with generally flat surfaces.

Abstract: The invention relates to a flexible pipe including a hose for carrying hydrocarbons and a connection endpiece at the end of the hose. The hose has an inner carcass, a sacrificial sublayer, and a sealing barrier. The endpiece has a tubular body in which the inner carcass, the sacrificial sublayer, and the sealing barrier are inserted. A sealing bush is crimped onto the sealing barrier. The endpiece includes a retaining ring secured to the inner carcass. A lock advantageously opposes axial displacement of the retaining ring in the direction for dissembling the hose from the endpiece.
