Method for producing a collecting line for detecting and locating a substance emerging in the vicinity of the collecting line in the event of a leak

摘要

A method for producing a collecting line, and a collecting line produced according to the method is provided for detecting and locating an agent discharging into the environment of the collecting line in case of leakage. Such a collecting line has a carrier pipe, the wall of which is equipped with openings that are sealed by an elastic material that is permeable for the agent. Accordingly, a hose made of the permeable elastic material, the inside diameter of which is smaller than the outside diameter of the carrier pipe, is elastically expanded by creating a pressure difference between the interior and the exterior of the hose. The carrier pipe is inserted into the radially expanded hose, and the radially expanded hose is attached to the outside surface of the carrier pipe by reducing the pressure difference.
