<p>The present invention relates to a device (1) for use with demounting flanges (2, 3) that are coupled by means of flange bolts (10), comprising a housing (6) with an inside (7) that is embodied for adjacent positioning at a radial outer circumference of said coupled flanges (2, 3), the device comprising a connection for removal of fluids that is released from between said flanges and the housing being embodied for being positioned against said coupled flanges while not obstructing said flange bolts. The device is characterized in that it further comprises an air intake (25) for supplying air from the surrounding to a space defined by the flanges and the device according to the invention. The invention also relates to a method for leak-free demounting flanges by using a device according to any of the preceding claims, comprising the step of positioning at a radial outer surface of said coupled flanges said housing, such that a separation seem of said flanges is covered by said device, with the proviso that the flange bolts are held freely; wherein the connection for removal of fluids is connected to a vacuum source or a pump and wherein the air intake provides for an uninterrupted connection between the surrounding and a space defined by the flanges and the device according to the invention.</p> |
