Method of rendering laid pipeline flexible and pipe joint suited for executing this method |
摘要 |
A method of rendering an existing pipeline flexible, by cutting out an intermediate portion of a pipe in a ring form, inserting a pipe joint into a cutout position, and connecting the pipe joint to the pipe. The pipe joint used in this method includes a plurality of sleeves interconnected in a fluid-tight condition to be oscillatable relative to one another. The pipe joint is inserted into the cut-out position and connected to the pipe, with the plurality of sleeves substantially fixed to one another while being interconnected in the fluid-tight condition to be oscillatable relative to one another. The sleeves are thereafter released from the fixed state.
