摘要： A geothermal heat containment barrier operable to be manipulated through an opening of a vault by at least partially folding the geothermal heat containment barrier, and positioned substantially horizontally against walls of the vault to reduce heat transfer through the barrier is provided. The barrier includes a central insulating core, a flexible outer frame, and an outer sealing trim. The central insulating core includes top and bottom outer surfaces and a perimeter edge. The central insulating core includes and/or contains an insulating material. The flexible outer frame has a shape memory and includes at least one flexible component having ends together such that the flexible outer frame is continuous and closed. The outer sealing trim is attached to the top and bottom outer surfaces and wraps around the perimeter edge of the central insulating core. The outer sealing trim is operable to press against the wall of the vault.

摘要： Bei einem Verfahren zur Errichtung eines Rohrleitungsabschnitts (6) eines Rohrsystems in einem Wärmenetz, welches zur Übertragung eines Wärmeübertragungsfluids zwischen einem Wärmelieferanten und mindestens einem Wärmeabnehmer vorgesehen ist, wird in einem Segmentierungsschritt der Rohrleitungsabschnitt (6) in mehrere Segmente (A, B, C, D, E) unterteilt, wobei für jedes Segment (A, B, C, D, E) auf der Grundlage von mindestens einer bodenphysikalischen Kenngröße eine Segmentkenngröße ermittelt wird und sich die ermittelten Segmentkenngrößen zweier benachbarter Segmente (A, B, C, D, E) um mehr als einen vorgegebenen Segmentkenngrößendifferenzwert unterscheiden. In einem Bettungsermittlungsschritt wird für jedes Segment (A, B, C, D, E) eine Segmenteinbettung eines in diesem Segment (A, B, C, D, E) in dem Graben eingebrachten Rohrleitungssegments (8, 9, 10, 11, 12) in einem wasserdurchlässigen Segmentbettungsmaterial so vorgegeben, dass innerhalb des Segments (A, B, C, D, E) ein über das Segment (A, B, C, D, E) gemittelter und auf eine Längeneinheit bezogener Wärmeverlust des in dem Rohrleitungssegment (8, 9, 10, 11, 12) übertragenen Wärmeübertragungsfluids geringer als ein vorgegebener Wärmeverlustgrenzwert ist. Ein entsprechend hergestellter Rohrleitungsabschnitt (6) weist demzufolge verschiedene Segmente (A, B, C, D, E) auf, in denen jeweils ein unterschiedliches Segmentbettungsmaterial zur Einbettung des Rohrleitungssegments (8, 9, 10, 11, 12) verwendet ist.

摘要： An insulated tubular assembly comprising jointed insulated tubing segments, all with inner and outer tubes concentrically disposed about in order to define a vacuum annulus in between and closed at both ends by annular bridges. Insulated tubing segments are provided with either male or female threads to threadably engage and form a joint directly with each other or through a coupling jointed to adjacent insulated tubing segments. An insulating sleeve held around such joint comprises a first tubular shell adapted to cover at least part of one insulated tubular segment and a second tubular shell overlapping either internally or externally part of the first tubular shell, such that the second tubular shell extends axially about the threaded joint from one annular bridge to the adjacent one, with high tolerances on lengths of the insulated tubing segment extension extending beyond their respective annular bridges.
