Abstract
A method of bracing an article, especially a junction between conduits subject to an internal pressure greater than that of their surroundings, which comprises applying thereto, in the order listed, a gas-impermeable member (this step may be omitted), a reinforcing member and a heat-recoverable member, the reinforcing member being radially inwardly deformable, at least at elevated temperatures, and heating the assembly to cause recovery of the heat recoverable member.
Claims21
A method of bracing a junction between cables which, in use, are pressurized, which comprises the steps of applying to the junction, in the order listed, a first sleeve, a substantially gas-impermeable member, which is subject to distortion by the internal pressure, a reinforcing member comprising a fibrous mat impregnated with a meltable material, and a second, heat-shrinkable sleeve, the reinforcing member being radially inwardly deformable at least at the recovery temperature of the second sleeve, and heating to recover the second sleeve.
A method of covering a junction between conduits subjected to an internal pressure greater than that of their surroundings, which method comprises:
- applying to the junction an assembly comprising a substantially gas-impermeable member that is subject to distortion by said internal pressure, a sleeve having upstanding rails, said rails being held in abutment by a channel, and a reinforcing member applied around said sleeve;
- applying a heat-recoverable member to said assembly, said reinforcing member being radially-inwardly deformable at least at the recovery temperature of said heat-recoverable member;
- and heating said heat-recoverable member to effect recovery thereof.
A method of bracing a junction between cables which, in use, are internally pressurized, which comprises the steps of applying to the junction, in the order listed, a first sleeve that is substantially gas-impermeable member and which is subject to distortion by the internal pressure, a reinforcing member comprising a fibrous mat impregnated with a meltable material, and a second, heat-shrinkable sleeve, the reinforcing member being radially inwardly deformable at least at the recoverable temperature of the second sleeve, and heating to shrink the second sleeve.
