Patent number: 7861983Abstract: The invention relates to a cold-insulated fixed-point pipe support for a low-temperature pipeline which includes an insulating system arranged between an outer shell and a supportable low-temperature pipeline having solid thermal insulating material which thermally insulates the pipeline from the low-temperature environment. A rotation-preventing and displacement-preventing device prevents rotation and displacement of the thermal insulating material with respect to the pipeline and an outer shell. A fixed-point pipe support is adapted to be fitted and removed in a substantially radial direction over the pipeline, and has at least one division with respect to shape with a division plane thereof extending perpendicular to a cross-sectional plane, and having a connecting device for releasable connecting and fixing shaped parts formed by the division.Type: GrantFiled: March 22, 2006Date of Patent: January 4, 2011Assignee: Lisega AktiengesellschaftInventors: Heinz-Wilhelm Lange, Ashley Challenor
