The invention relates to a pipe which can be fitted into an appliance of small dimensions which, on contact with the pressurized irrigation liquid contained in a pipeline or boom, is intended to dispense this liquid at a low flow rate (from one to eight litres per hour). This pipe is composed of an engraved part 8 of specific shape produced in a convertible material, which engraved part, being applied in a sealed manner to a wall, defines a pipe comprising a feed orifice 21 and a discharge orifice 4 for the irrigation liquid. This product thus produced avoids obstructions due to the accumulation of line particles. <IMAGE>
