Abstract

A method is provided for sealing an electrical cable joint or termination, which method comprises mixing a multicomponent PU resin composition, introducing the mixed PU resin composition into a housing comprising one or more electric cables and allowing the resin composition to cure, wherein the multicomponent PU resin composition has a free isocyanate content of not more than 0.1% by weight, and a viscosity that is less than 8000 mPa.s at 25 °C. Also provided is an insulated electrical cable joint or termination, comprising the cured multicomponent PU resin composition. Moreover, a multicomponent electrically-insulating PU resin composition is provided, for cable joints and terminations, that may be applied professionally without requiring special training and that is preferably label-free, as well as a kit comprising the multicomponent electrically-insulating PU resin composition and a housing.

Abstract

Method for sealing an electric cable joint wherein use is made of a prefabricated sealing assembly which comprises an impervious sheet that is at least partially transparent stretchable in a direction between opposed transverse ends. An open structure spacer mat is fixed on the inner side of the sheet and is stretchable the same direction as the sheet. A pair of air-permeable and resin compound blocking strips is mounted to the inner side of the sheet so that the spacer mat is located axially between these strips. The assembly further comprises a resin compound transfer member secured to the sheet. The method comprises arranging the prefabricated sealing assembly relative to the electric cable joint, retaining a first transverse end of the sheet, and wrapping the sealing assembly circumferentially about the electric cable joint. Herein the sealing assembly overlaps itself. The wrapping involves the exertion of a stretching force away from the retained first transverse end so that the sealing assembly is locally stretched into conformity with the electric cable joint. The second transverse end is secured onto the wrapped sealing assembly. A liquid resin compound is introduced via the resin compound transfer member into the space delimited by the sealing assembly, so that the space is filled whilst air is expelled via said air-permeable and resin compound blocking strips and so that the cable joint becomes embedded in the resin compound, which resin compound hardens thereafter.

Abstract

A method for plugging an abandoned oil and/or gas production wellbore, the method comprising providing a top seal plug down-hole the wellbore, wherein the top seal plug is assembled as a mixture of a resin and spherical beads within the resin. The neighbouring beads within the resin contact each other. The resin is a cross linked resin system setting with temperatures from 10-120°C. The spherical beads are essentially nonporous, non-swellable and non-compressible.

Abstract

A protective plastic pipe end fitting system (1) to be mounted at an end portion of a protective plastic pipe (10) into which at least one elongated object (5), for example a cable or another, smaller diameter, plastic pipe, passes. The system comprises a housing (20) of one or more rigid plastic housing parts and a compressible sealing member (30). The housing (20) delimits a pipe bore (21) and a sealing member receiving chamber (23). The sealing member body (31) is split and the pipe bore (21) is laterally open allowing to mount the sealing member (30) and the housing (20) about an elongated object (5) that extends from the end portion of the protective pipe. The housing (20) has a least one first engaged helical thread creating portion (40) which is adapted to create a helical thread (50) having a lead into the exterior of the protective plastic pipe (10) upon screwing the fitting system (1) onto the end portion (11) of the pipe. The pipe comes into contact with the pipe contacting end face of the sealing member (30) and upon continuing said screwing the compressible sealing member becomes compressed thereby sealing onto the end of the pipe.

Abstract

A disposable and collapsible bag packaging and connector system. The system includes a disposable and collapsible bag (1) having a chamber (2) that is filled or to be filled with a flowable product. The bag has a first connector (10) for dispensing the product from the bag, the first connector being permanently secured to the bag. The system includes a second connector (40) having an internal channel (41) for passage of the product, which second connector is releasably connectable to the first connector. The first and second connectors form a bayonet connection. The first connector comprises a rotary valve member (20) that upon rotation over an angle of the inserted connector relative to the other connector opens and closes the bag.
