Product Summary

Duct coupling is a coupling which is used in the duck. An improved duct is proposed which comprises a plurality of duct sections coupled together. Each duct section has a turned-up portion and a flange at one end and a flange at the other end. Both the turned-up portion and the flanges are formed by bending the edge of each duct section. The turned-up portion of one tubular body is inserted into the not-turned-up end of an adjacent tubular body. A coupling for coupling together two mutually coaxial, rotatable parts, comprising a substantially cylindrical coupling member which is intended to be mounted between the parts to be coupled together and which is expandable both radially outwards and radially inwards so as to exert on the parts a coupling pressure through the intermediary of the coupling member. The coupling member incorporates a pressure chamber which is intended to be supplied with pressure fluid for expansion of the coupling member and which is provided with a pressure relief device which is triggered upon relative rotation of the aforementioned parts.
