GAS-INSULATED PIPELINE SYSTEM WITH AN INNER LINE SUPPORTED BY COLUMN-TYPE SUPPORT STRUCTURES

摘要

The invention relates to a gas-insulated pipeline system. The support areas of the pipe-shaped inner line (1), which are formed with the aid of column-type support structures, are modified so as to simplify the production, transport and handling of said inner line in such a way that the inner line in the support area is formed by a short pipe-shaped intermediate part (4) produced by casting. The ends of said intermediate part are connected to the adjoining sections of the inner line (43, 44, 45) and form a single piece with each blind-hole type sleeve (41) which surrounds the one end of the column-type support structure (31).
