Dispositif d'absorption des dilatations thermiques d'un revêtement d'acier. Dans un récipient de pression précontraint en matière coulée, muni d'un revêtement d'acier, un tube de blindage est inséré à travers ce revêtement et le récipient. Le tube de blindage 4 comporte, à son orifice dirigé vers l'intérieur du récipient 1, un élément de maintien périphérique en forme de col 5, ouvert vers l'intérieur du récipient, dont une extrémité est soudée au revêtement 2 de façon étanche aux gaz. An arrangement for absorbing the thermal expansions of the steel lining of a prestressed cast pressure tank by means of the mounting support of an armored or steel-plated pipe which is passed through the lining and the prestressed cast pressure tank. The steel-plated pipe, at that opening thereof which faces the interior of the tank, has a circumferential, collar-like mounting support which is open toward the interior of the tank. One end of the mounting support is welded to the lining in such a way that the connection is impermeable to gas. The shoulder of the mounting support is positively connected with the cast pressure tank.
