    摘要: High-pressure pipe element made of a hooped tube for making lines referred to as kill lines and choke lines that equip oil production installations, notably offshore. The high-pressure pipe element is an assembly consisting of two connections (3) and (4) respectively welded to the two ends of a metallic tube (1). The metallic assembly is hooped. Hooping (2) covering tube (1) comprises a sufficient number of hooping layers to withstand a determined internal pressure. Transition zones (5) and (7) in the vicinity of the welds comprise additional hooping layers.
