The invention relates to a piping component 13, 14, such as a pipe, fire plate, regulator plate, angled part and branch part. In order to facilitate the rapid production of different types of pipe ducting systems, which must also be easy to inspect, maintain and overhaul, the piping component 13 has a flange collar 15 at both of its ends, which comprises an outer circular part 16 and an inner circular part 17, which outer circular part forms an obtuse angle α with the outer shell 19 of the piping component and functions as a clamping surface 18 for a clamping band 20, a sealing ring 30 of flexible material is arranged between the outer circular part and the inner circular part and projects out from the end of the piping component 13 further than the said outer and inner circular parts, and which allows two piping components 13 and 14 to be coupled with their ends facing one another by means of two clamping bands, in such a way that only the ring seals are in direct contact with one another. The invention also relates to a coupling part for coupling two piping components to one another. <IMAGE>
