摘要 <p>PCT No. PCT/FR92/00175 Sec. 371 Date Feb. 22, 1994 Sec. 102(e) Date Feb. 22, 1994 PCT Filed Feb. 26, 1992 PCT Pub. No. WO92/14962 PCT Pub. Date Sep. 3, 1992.The invention describes a pipe for carrying fluid, including thermally insulated steel pipe sections of a type including an outer tubular shell, an inner cylindrical shell of smaller diameter, in the inner shell being sealingly welded to the outer shell at each of the ends of the pipe sections. It is characterized in that at each joint, the ends of the two inner shells are welded to each other, and a sleeve links to the ends of the outer shells so that when traction, compression or bending forces are exerted on the pipe, the said sleeve transmits these forces to the outer shells.</p>
