ARRANGEMENT FOR ATTACHING TWO METALLIC DUCTING PARTS OF AIR DISTRIBUTION DUCTING AND A DUCTING PART

摘要

An arrangement for attaching two metallic ducting parts, such as ducting pipes (1), of air distribution ducting, which arrangement comprises an essentially straight pipe section on one end of a ducting pipe (1). The invention is implemented in such a way that on the opposite end of a ducting part, the ducting part comprises a joint end (1') having a diameter larger than the aforementioned straight pipe section, and that a groove (2) is formed in the joint end (1'), in which groove a seal (4) is arranged on the inside of the joint end (1'), and that the straight pipe section of the ducting pipe is arranged to be pushed into the joint end of a second ducting pipe.
