The flanged sealing ring can be used in a device for detecting components of a flanged sealing ring in a pipeline system that includes a plurality of pipes, at least two of which are held against each other at a flange in such a way that sealing is effected by a flanged sealing ring. Using a metal detector and a gate for removing a metal-containing substance from the pipeline, which gate is arranged behind the metal detector in the conveying direction, the flanged sealing ring can then be detected, and therefore, when components of the flanged sealing ring detach, detection can be performed at the metal detector and discharging can be performed at the gate. ## Claims ### Claim at position 1 1-13. (canceled) ### Claim 14 A flanged sealing ring for sealing a pipe connection, the flanged sealing ring comprising: a metallic fraction substantially homogeneously in the flanged sealing ring. ### Claim 15 (depends on 14) The flanged sealing ring of claim 14, wherein the metallic fraction is between 0.5% by weight and 10% by weight. ### Claim 16 (depends on 14) The flanged sealing ring of claim 14, wherein metallic particles of the metallic fraction have a maximum size of less than 100μ. ### Claim 17 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring has an organic material fraction with polydimethylsiloxane. ### Claim 18 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring consists of a material approved for a food sector according to EC Regulations No. 1935/2004 and/or FDA 21 CFR Ch. I, §177.2600. ### Claim 19 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring is made from an extruded continuous strand, which is fixed at a seam location by vulcanization. ### Claim 20 (depends on 14) The flanged sealing ring of claim 14, wherein the metallic fraction is iron oxide particles. ### Claim 21 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring has a Shore hardness of 50 to 65 KME according to DIN 53505-A at 23° C. and d=6 mm. ### Claim 22 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring has a tear strength according to DIN 53504-S1 of 7 to 11 N/mm2 at 23° C. and d=2 mm. ### Claim 23 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring has an elongation at tear according to DIN 53504-S1 of 300% at 23° C. and d=2 mm. ### Claim 24 (depends on 14) The flanged sealing ring of claim 14, wherein the flanged sealing ring has a rebound resilience according to DIN 53512 of between 40% to 60% at 23° C. and d=12 mm. ### Claim 25 A pipeline system, comprising: several pipes forming a pipeline for conveying a flow of material, wherein at least two pipes are held in a sealed manner on each other at a flange via a flanged sealing ring; a metal detector arranged at the pipeline; and a gate arranged behind the metal detector in a conveying direction, wherein the gate is arranged to remove a metal-containing substance from the pipeline, wherein the flanged sealing ring is made from a material with a metallic fraction, so that during detachment of components of the flanged sealing ring the metal detector can detect the detached components, which are discharged at the gate. ### Claim 26 (depends on 25) The pipeline system of claim 25, wherein the flanged sealing ring comprises a web arranged between the flanges of the at least two pipes, and the flanges are held in a clamped manner by a clamping ring.
