Definitions
- Figure 1 illustrates an end portion of a liner 1, made from such as plastics material.
- the liner 1 has at one end a sleeve-shaped seal 2 on its outside for the purpose of providing sealing engagement between the liner and a surrounding pipe 3.
- the inventive seal 2, e.g. made from rubber material, in an inactivated state has at one end a conical deflecting lip 10.
- the lip 10 is relatively thick-walled and to advantage it has a waist 11 for obtaining the desired resiliency, the waist also positively affecting the ability of the lip to adjust itself into good engagement against the outer pipe.
- the top lip has an end surface for sealing engagement against a surrounding pipe 3.
- seal 2 is evacuated from air before injecting filler, as illustrated in Figures 1 and 4, since air possibly enclosed in the cavity 14 after completed injection of filler can leak out from the seal after a time and thereby jeopardise the long-time function of the seal.
- the manufacturing process used in manufacturing the seal ensures that it will be practically exhausted from air.
- a cement grout of the type which expands somewhat on curing may be mentioned a cement grout of the type which expands somewhat on curing.
