<p>A connector suitable for connecting two sections of pipe together, which is particularly useful for connecting sections of pipe with an outer pipe and a polymeric or elastomeric liner pipe located concentrically within the outer pipe. The connector has a body having at least one free end with a seal assembly provided on the free end, the seal assembly and the free end are configured to be received axially within the bore of the liner pipe, and are configured to seal against the inner surface of the liner pipe. The connector has a flange extending radially from the body and having sealing formations to seal against the inner surface of the outer pipe. The sealing assembly can be moulded onto the ends of the body and can be formed of a polymericor elastomeric material. The profiled sealing assembly is therefore designed to seal against the bore of both the outer pipe and the polymeric or elastomeric liner pipe. When the connector is pushed into the prepared end of a lined pipe, or when the next length of pipe is offered to the connector, sealing is achieved by material displacement at the ribbed interfaces.</p> |
