Spiral pipe semi-flexible air ducts are specially designed, multi-purpose semi-flexible air ducts for flue connections of devices operating with all kinds of fuels (natural gas, LPG, fuel-oil, etc.), extremely hot air transfer systems operating at high pressure, and especially for applications requiring high mechanical strength. It is produced by shrinking and interlocking pure metal 316 L quality galvanized strips with a special production technique. Galvanized semi-flexible air ducts have the ability to bend, twist and stretch. It is easy to install in oval and round joints. The clamp system used in Ünveren stainless steel semi-flexible air ducts is UAS, namely double clamp system. In the UAS clamp system, the clamp becomes stronger as the material is stretched. There is no separation and/or deformation of pure metal stainless steel strips from each other during bending, bending, extension and stretching.
