Fluid conduit with pressure display measures

摘要

The fluid line (1) has a line wall (4) with a fluid channel (3) for low pressure fluid. The line wall has a display medium (5) pressurized by the fluid pressure. The fluid pressure is controlled in the fluid channel. The display particles (16) are embedded appropriately in a base material (15). The base material is plastic foam, particularly closed-porous plastic foam. The base material is acted around a polyurethane-foam.
