The end-fitting (10) also comprises means (24a, 24b) for mechanically anchoring the second armour layer (4) to the end-fitting (10). The first (2) and second (4) armour layers are electrically insulated from each other by at least one electrically insulating layer (3) in the end-fitting (10) and the end-fitting (10) comprises a local volume (35) in the end-fitting (10) adjacent to the electrically insulating layer (3) adapted for injection of a functional fluid.
Abstract:
A method and apparatus are disclosed for re-terminating an end of a flexible pipe. The method comprises removing at least one original end fitting component (310, 335) from a multicomponent end fitting, secured to flexible pipe body at an end of a flexible pipe, leaving a retained portion (330, 360) of the end fitting in situ and subsequently securing at least one superseding end fitting component (310, 335) to the retained portion thereby providing a new fluid tight seal against a fluid retaining layer of the flexible pipe at a new sealing location axially displaced from an original sealing location.

A method is provided for manufacturing a polymeric film with thermal management capabilities. The method comprises mixing at least three compounds, wherein a first compound comprises a polymeric phase change material, a second compound comprises an additive, and a third compound comprises a molecule that, in its liquid form, acts as a solvent of the first and second compounds, and which is curable into a solid form as a polymer. Then, the method comprises applying a mixture of the first, second, and third compounds in a liquid form to a substrate, and curing the mixture into a solid state.
Abstract:
A pipe-in-pipe assembly comprises thermally-insulating spacers (24) positioned in an annulus (16) to act radially between inner and outer pipes (12, 18). The spacers comprise at least one circumferentially-extending array of circumferentially-spaced ribs (26) that define longitudinally-extending passageways in gaps (28) between neighbouring ribs of the array. Cables (10) including heating elements extend longitudinally along the annulus outside the inner pipe. The cables extend longitudinally along the passageways. At least one insulation layer (48, 52) disposed radially outboard of the cables comprises insulating elements disposed in the gaps between the ribs and/or an insulating layer extending around the inner pipe, positioned radially outboard of the ribs and bridging the gaps. Bands encircle and retain components of the insulation layer. Insulation may also be disposed on the inner pipe between first and second arrays of ribs, those arrays being spaced longitudinally from each other.
Abstract:
A bulk adhesive transfer system (10) for transferring adhesive particulate to a melter (18, 200) includes a bulk supply (12) and a transfer device (14, 150, 250, 350), which may define a hopper (152, 252, 352) of the melter (18, 200), a mobile bin (14, 150), and/or a buffer unit (16). The transfer device (14, 150, 250, 350) is configured to receive unmelted adhesive particulate from the bulk supply (12) and then be selectively docked with the melter (18, 200) to transfer the adhesive particulate to the melter (18, 200). The bulk adhesive transfer system (10) may also include a knife gate valve device (1 10), which includes a plurality of ports (122a, 122b, 122c, 122d) that sequentially open and close to control flow of the adhesive particulate towards the melter (18, 200). The bulk adhesive transfer system (10) simplifies refilling operations for a melter (18, 200) while enabling continuous operation of the melter (18, 200), even when the transfer device (14, 150, 250, 350) is undocked for removal from the melter (18, 200).

An elongated heat trace element comprised of first and second heat tubes is aligned and coupled to at least a portion of an outer surface of the fluid pipeline. The outer surface of fluid pipeline carries a first insulation material covering a first portion of the outer surface. The outer surface of the fluid pipeline further carries a second insulation material covering a second portion of the outer surface and wherein the second portion of the outer surface is different than the first portion of the outer surface. The first and second insulation materials are configured to cover the outer surface of the fluid pipeline. The fluid pipeline further comprises a third insulation material carried over a second outer surface defined by the cooperation of the first and second insulation materials.

Erfindungsgemäß ist vorgesehen, dass bei dem Verfahren eine kombinierte Heiz- und Kühlvor- richtung (19) verwendet wird, die Heizbereiche (21) und Kühlbereiche (22) aufweist. Diese Vorrichtung kann entlang des zu beschichtenden Rohres (11) geführt werden, wobei im Rohrinneren ein den Beschichtungswerkstof f enthaltendes Fluid (16) zugeführt wird. Durch die kombinierte Heiz- und Kühlbehandlung des Rohres wird der Schichtbildungsprozess unterstützt. Der Kühlvorgang wird im Unterschied zum Stand der Technik durch den Einsatz des Kühlbereiches (22) einem gewünschten Profil unterworfen und nicht dem Zufall überlassen.
