<p>System for loading and unloading of cold media, for example LNG or LPG, to or from a vessel, through pipes (1) connected with ball joints, where the pipes are insulated, and where each ball joint's inside part (4) has an inside pipe (3) which is sealed against the inside part (4) substantially over the latter extent, and which thereby forms an inside annulus (6) which can be evacuated, and that each ball joint's outside part (10) is surrounded by an outside annulus (9) which also may be evacuated.</p> |
