ている。 BACKGROUND OF THE INVENTION Fluid handling arms consisting of articulated tubes are widely used in the petroleum industry to transfer oil and other fluids between a handling station such as a pier and a tanker. Such cargo handling arms are generally
The inner tube is supported by a vertical riser tube through a plurality of tube swivel joints for pivoting about vertical and horizontal axes, and the outer tube is connected to the inner tube through a tube swivel joint to allow pivoting about a horizontal axis. The tube is pivotable about the tube relative to the inner tube. The outer end of the outer tube is adapted for connection to a tanker tube manifold located within reach of the cargo handling arm.

る。 Some of the fluids transported by the handling arm have special properties, for example corrosive properties. Corrosive fluid transport pipes must be made of stainless steel or other relatively difficult to machine materials. In order to make the fluid transport tubes of the arms self-supporting, they must be made of thick-walled, heavy tubes and coupling elements, which would be very expensive if made of corrosion-resistant materials. Other prior art handling arms include support structures (beams or truss assemblies) made of common steel or other relatively inexpensive materials that support relatively lightweight, corrosion-resistant material fluid transport pipes. However, the differential thermal expansion and contraction of fluid transport tubes and their supporting structures creates serious problems when transporting cold fluids.

要望されている。 Therefore, a relatively lightweight fluid transport tube that can be made of a material that has the necessary properties to transport corrosive or cold fluids, and a separate support structure that can be made of a relatively inexpensive and easily fabricated material. What is needed is a cargo handling arm comprising a body and adapted to connect to and support a fluid transport pipe in a manner that allows the support structure to fully absorb differential thermal expansion and contraction with the fluid transport pipe.
