BILATERATED FLEXIBLE PIPE JOINTS LOCATED ON A SINGLE AXLE BASIS AND ADDITIONAL RING ELASTOMIC FLEXIBLE ELEMENTS

摘要

1. A two-way flexible pipe connection, including: an outer casing; a first extension pipe extending from the first end of the casing; a second extension pipe extending from the second end of the casing; a first main ring-shaped elastomeric flexible element located on the casing and facilitating the installation of the first extension pipe; a second main annular elastomeric flexible element located on the housing and facilitating installation of a second extension pipe on the housing; an internal housing located inside the external housing; a first additional annular elastomeric flexible element located in the inner housing and facilitating the installation of a first extension pipes; and a second additional ring-shaped elastomeric flexible element located in the inner case and facilitating the installation of a second extension pipe on the inner case; in which the load on the first and second extension pipes causes each of the first and second main flexible elements and each of the first and second additional flexible elements to be compressed state; and in which the first and second additional flexible elements are attached to the inner casing to contain fluid pressure inside the first and second extension pipes so that the first and second main flexible elements are not subjected to liquid pressure inside the first and second extension pipes. 2. The two-way flexible pipe connection according to claim 1, in which the first and second main flexible elements and the first and second additional flexible elements are installed coaxially and have a common center rotated
