A light head for use in relining a pipe is disclosed. The light head comprises a proximal end cap, a distal end cap, and at least one body between the proximal end cap and the distal end cap. The proximal end cap also has an air inlet. The body has a longitudinal hole extending from the proximal end cap through the centre of the body towards the distal end cap and at least one air channel extending radially from the longitudinal hole to a radial air outlet. The longitudinal hole is configured to receive air from the air inlet such that in use air from the air inlet passes through the body and exits at the radial air outlet. The body is configured for supporting at least one light emitting diode on the periphery of the body in order to emit light radially from the light head towards the pipe.

A system for in situ rehabilitation of a corrugated culvert or other conduit includes a support frame coupled to an inner surface of the culvert. The support frame provides attachment points that are spaced away from the inner surface of the culvert. An assembly of interconnected longitudinal planks is coupled to the support frame and forms a liner within the culvert. Each longitudinal plank has an inwardly facing surface that forms a portion of an inner surface of the liner and an outwardly facing surface opposite the inwardly facing surface. At least one longitudinal protrusion extends away from the outwardly facing surface of each longitudinal plank. A layer of a cured cementitious grout material fills or substantially fills a space between the inner surface of the host pipe and the plurality of interconnected planks, and the at least one longitudinal protrusion of each longitudinal plank is embedded within the cured cementitious grout material.

An end stopper (10) for liner systems for pipe and sewer rehabilitation with a liner which is arranged between two end stoppers (10) and can be acted upon by a pressure medium and can be applied reversibly to the circumference of the end stopper (10), is characterized in that the end stopper (10) is composed, in cross section, of a plurality of profile parts (100, 101, 102, 103, 104, 105) which are of part annular and/or part tubular shape and are conical, wherein at least one profile part (100) has a configuration that tapers conically from the inside to the outside.

A sealing element (10) for use in a fluid-carrying pipeline (16) comprising a substantially central core (14) surrounded by a coating (12). The outer coating (12) is adapted to perform a partial extrusion through an opening (15) in a pipeline wall (16) to seal the opening (15). The density of the sealing element (10) is substantially the same as the density of the fluid (11) in the pipeline (16). The coating (12) comprises a two-part epoxy putty, and the core (14) is formed from a deformable material. A method of making the sealing element is also disclosed.

Example aspects of a pipe repair stent, a pipe repair device, and a method for repairing a pipe are disclosed. The pipe repair stent can comprise a sealing layer comprising a flexible and compressible repair material; and a spring, wherein the sealing layer is wrapped around a circumference of the spring; wherein the stent is configurable in an expanded configuration and a compressed configuration, the spring biasing the stent to the expanded configuration.

A magnetic patch system includes a sealing member configured for attachment to a pipeline proximate to a breach in a wall of the pipeline. A magnet is positioned at least partially within a housing arrangement. The magnet may be oriented to generate a force toward the wall of the pipeline to attach the housing arrangement to the wall of the pipeline and capture the sealing member between the housing arrangement and the wall of the pipeline. The system may be installed inside a pipeline using a remotely controlled robotic system.

A method for relining a pipeline includes using a composition of (a) a resin crosslinkable by a photoinitiator activated by an actinic light; (b) a resin that can stay inert or be cross-linked by a co-hardening booster; (c) a photoinitiator compound that is photoactivatable by irradiation with an actinic light source; and d) optionally, a booster/co-hardener compound that acts as a crosslinker of the inert resin to increase the overall mechanical, thermal and chemical strengths of the system. A kit for relining a pipeline with such method includes a first container housing (a), (b) and (c); a second container housing (d), which may be used optionally; a substrate suitable for being impregnated with the composition of the first container alone and optionally with the composition resulting from mixing the contents of the first and the second container; and, optionally, an actinic light source and an adjustable pressure air flow generator.
