Abstract:
1. A method for producing a collecting line for detecting and locating an agent discharging into an environment of the collecting line in a case of leakage, the collecting line containing a carrier pipe having a wall with a plurality of openings formed therein, the openings being sealed by a resilient material being permeable for the agent, which comprises the steps of: resiliently expanding a hose, at least over a portion of a length of the hose, the hose being made of a permeable resilient material and having an inside diameter being a same size as or smaller than an outside diameter of the carrier pipe, by generating a difference in pressure between an interior and an exterior of the hose by the further steps of: introducing the carrier pipe into the hose being a radially expanded hose; and placing the radially expanded hose against an outer surface of the carrier pipe by reducing a difference in pressure.
