LIQUID EXTRACTING STRUCTURE OF BURIED PIPING

摘要

PROBLEM TO BE SOLVED: To provide the most suitable liquid extracting structure of buried piping for liquid extracting of the buried piping so as to transport cryogenic liquid such as LNG.

SOLUTION: The liquid extracting structure of the buried piping is buried under the ground and used for transportation piping of cryogenic liquid. In the liquid extracting structure of the buried piping, a branching section is attached to an outside lower part of the transportation piping and provided with liquid extraction piping connected to the branching section, and equipped with heat insulating material for covering the transportation piping and the liquid extracting piping and an outer piping for housing the heat insulating material. It is desirable that the liquid extracting piping covered with the heat insulating material is provided.
