Definitions

  • This invention relates to the production of clad pipes and other tubular structures having inner and outer tubular sections with an interference fit therebetween.
  • a clad pipe typically comprises inner and outer pipe sections with an interference fit therebetween. Clad pipes typically combine the required properties of the inner and outer pipe sections.
  • a clad pipe may, for example, have an inner pipe section selected for particular characteristics such as heat and/or corrosion resistance, and an outer pipe section also selected for particular characteristics such as relatively low cost, high strength, ductility and/or weldability.
  • a further disadvantage arises because of the care needed to ensure that there is no water ingress between the inner and outer pipe sections, as water ingress can lead to welding and other quality problems.
  • a still further disadvantage is that pistons used for closing the ends of the inner pipe section can cause deformation or other damage to the clad pipe.
  • Another manufacturing process involves subjecting the inner and outer pipe sections to thermal treatment prior to their being brought together. Specifically, the outer pipe is heated in order to cause it to undergo radial expansion, and the inner pipe section is cooled in order to cause it to undergo radial contraction.
  • the contracted inner pipe section is inserted into the expanded outer pipe section, and the pipe sections returned to ambient temperature, with the result that the outer pipe section contracts onto the inner pipe section and the inner pipe section expands onto the outer pipe section, thereby providing an interference fit therebetween.
  • Such a process can be complicated, as it does require facilities for heating and cooling the pipe sections.
  • a method of manufacturing a tubular structure having inner and outer tube sections with an interference fit therebetween comprising the following steps:
  • the inner tube section is radially expanded into a condition which it undergoes plastic deformation and the outer tube section is radially expanded to undergo elastic but not plastic deformation, interference between the inner and outer tube sections is achieved due to the residual tensile stress in the outer tube section and the residual compression stress in the inner tube section.
  • the expansion steps (b) and (c) are applied sequentially from one end of the assembly to the other.
  • the sequence can be varied, if desired.
  • the sequence can commence at a location intermediate the ends of the assembly and progressively advance towards one end and then the other.
  • the confronting surface of either one or both of the two tube sections can be pre- treated to enhance a mechanical bond therebetween, if so desired.
  • the pre-treatment may involve roughening the surface, such as by way of an abrasive blasting process.
  • the method may also involve establishing a metallurgical bond between the confronting surfaces of the two tube sections.
  • the ends of the tubular structure may be sealed in any appropriate way to prevent ingress of moisture and any other contaminants between the inner and outer tube sections.
  • the ends of the tubular structure may be sealed by, for example, welding.
  • the end of one tube section may be disposed inwardly of the corresponding end of the other tube section, and the resultant exposed bond portion of the other tube section clad with an overlay forming a metallurgical bond with the other tube section and also a metallurgical seal between the two tube sections.

Abstract

L'invention concerne un procédé de fabrication d'une structure tubulaire, notamment un tuyau gainé (10) ayant des sections interne et externe (11, 12) présentant un espacement intermédiaire et un tuyau gainé (10) fabriqué d'après ce procédé. Le procédé consiste à : (a) placer deux sections de tuyau l'une dans l'autre afin d'obtenir un assemblage (15) comprenant la section de tuyau interne (11) et la section de tuyau externe (13) ; (b) étendre radialement une partie de la section (11) en insertion avec la partie enveloppant la section (13) à l'aide d'un outil d'extension (17) ; (c) continuer l'extension radiale de ladite partie de la section (11) pour étendre plastiquement ladite partie sur la section (13) et étendre élastiquement la partie enveloppant la section (13) ; et (d) répéter les étapes (b) et (c) pour en ou plusieurs parties de la section (11). Etant donné que la section interne (11) est radialement étendue dans un état subissant une déformation plastique et que la section externe (13) est étendue radialement pour subir une déformation plastique, l'espacement entre les sections interne et externe est effectué en raison de la contrainte de traction résiduelle dans la section (13) et de la contrainte de compression résiduelle dans la section (11). Le procédé peut également faire intervenir une liaison métallurgique entre les surfaces opposées des deux sections (11, 13).
