Abstract
A sleeve (10) for use as a mould for protecting, repairing or renovating a pipe (12) for carrying water, gas or other fluids. A liquid material such as polyurethane or epoxy resin is injected into the sleeve so that, as it polymerizes, it protects or seals the pipe section covered by the sleeve. The sleeve includes a plurality of identical modules (14, 16, 18, 20, 22) assembled to form the mould and each including a male portion and a female portion linked by an intermediate portion. The male portion of one module is designed to fit into the female portion of the adjacent module.
