Abstract
The invention concerns a method for forming curved conduit sections with steel tubes (16) provided with a mortar coat (14) inside. The method is characterised in that it consists in: working at least a ring-shaped groove (12) in the mortar coating (14) and bending the steel tube (16) at said ring-shaped groove (12), which can then be closed again with mortar. Said method is particularly adapted to form curved conduit sections when water-supply conduits are being laid, consisting of steel tubes (16) provided on the inside with a cement mortar coating (14) and on the outside with a PE or PP coat.
