Method for transporting easily polymerizable liquid by pipeline
View Patent ↗A method for transporting an easily polymerizable liquid by a pipeline having branches, wherein among pipelines branched at a branch point, one pipeline which may not be used over a long period of time, is provided with a valve to close the pipeline, within 500 mm from the branch point.
1. A method for transporting an easily polymerizable liquid by a pipeline, said method comprising:
providing the pipeline with a bypass pipeline having a length of at most 1000 mm to bypass a part of the pipeline; and
providing the bypass pipeline with only one valve to close the bypass pipeline, the valve being within 500 mm from the attached point at each end of the bypass pipeline.
2. The method according to claim 1 , wherein at least a part of the bypass pipeline is installed at an elevation higher than the main pipeline.
3. The method according to claim 1 , wherein at least a part of the branched portion or the connected portion of the bypass pipeline extends upwards from the main pipeline at an inclination angle of from 3 to 90°.
4. The method according to claim 1 , wherein one end of the bypass pipeline is branched from a position at a same height as the main pipeline, and the valve is disposed at a portion of the bypass pipeline located at said same height.
