Abstract: Curing method and apparatus for curing the lining (4) of a pipe (3) and which comprises a traveling frame (2) for introduction into the pipe (3), a curing device (8) mounted on the frame (2) and operative to cure the inner wall of the lining during travel of the frame along the pipe, and a fluid pressure driven propelling device (11) connected to the frame (2) and operative, upon application of fluid pressure to the pipe, to pull the frame along the pipe.

Abstract: A method of re-lining a main pipeline having at least one transversely extending pipe connected thereto via a generally annular connection region includes applying an internal lining to the inner wall of a length of the main pipeline and which overlies the entrance to the transversely extending pipe. A hole is then formed in the lining so as to expose the entrance. A re-lining assembly is introduced into the pipe from an end thereof remote from the entrance, the assembly comprising a tubular web of resin-permeated material within an elastomeric membrane which is everted by application of fluid pressure to the assembly so as to introduce the assembly into the pipe and so that the now externally located tubular web projects into the main pipeline. Fluid pressure is further applied to the assembly so that the membrane causes the projecting end of the tubular web to flare or deform outwardly and thereby overlie the connection region.
