<p>Apparatus for curing an ultraviolet light curable repair material (31) is described, which is particularly suitable for lining conduits in need of repair. The apparatus comprises ultraviolet light sources (5, 7) accommodated within an expandable sheath (27) which extends between two end caps (1, 3). The light sources (5, 7) are coupled to each other via flexible coupling (23), and each of the light sources is coupled to one of the end caps via couplings (21, 25). The apparatus includes means to transport the apparatus to the desired location.</p> |
