Abstract
System for sealing in a conduit a space between an inner wall of the conduit and at least one pipe or cable extending through the conduit, wherein the system comprises: at least one rubber element for providing in the conduit a support-structure which is clampable between the inner wall and the at least one pipe or cable; and a sealant for application against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable.
Claims39
A system for sealing in a conduit a space between an inner wail of the conduit and at least one pipe or cable extending through the conduit, wherein the system comprises:
- at least one rubber element for providing in the conduit a support-structure which is clampable between the inner wall and the at least one pipe or cable;
- and a sealant for application against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a fire-resistant vulcanized rubber of a thermally substantially non-expandable type, and wherein the sealant is made of a fire-resistant polymer which is vulcanizable at room temperature under exposure to humidity and which is also of the thermally substantially non-expandable type, wherein rubber or polymer of the thermally substantially non-expandable type comprises rubber or polymer, respectively, which is free from components which would on heating cause the rubber or the polymer to expand to an extent larger than the extent to which the rubber or the polymer itself expands on such heating, wherein the rubber element is a longitudinal element and the longitudinal rubber element is a tubular element, or wherein a number of the longitudinal rubber elements can together form one tubular element.

A method for sealing in a conduit a space between an inner wall of the conduit and at least one pipe or cable extending through the conduit, wherein the method comprises:
- providing at least one rubber element for placement in the conduit a support-structure which is damnable between the inner wall and the at least one pipe or cable;
- and a sealant for application against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a fire-resistant vulcanized rubber of a thermally substantially non-expandable type, and wherein the sealant is made of a fire-resistant polymer which is vulcanizable at room temperature under exposure to humidity and which is also of the thermally substantially non-expandable type, wherein rubber or polymer of the thermally substantially non-expandable type comprises rubber or polymer, respectively, which is free from components which would on heating cause the rubber or the polymer to expand to an extent larger than the extent to which the rubber or the polymer itself expands on such heating, wherein the rubber element is a longitudinal element and the longitudinal rubber element is a tubular element, or wherein a number of the longitudinal rubber elements can together form one tubular element;
- placing in the conduit the at least one rubber element;
- and
- sealing at least one end of the conduit with the sealant.
