ABSTRACT:
The present invention relates to an apparatus for securely fastening joints in pressure vessels, pipes, and other structures intended to isolate internal volumes from the external environment. It can join a blank cover to a pressure vessel or it can join tubular members. It may be used in any application currently utilizing standard bolted flanges. It provides a flange retaining clamp for remotely disconnecting and remotely connecting flange members disposed on a pressure vessel, in which one of the flange members is disposed on the pressure vessel and the second flange hub end is applied in a gasketed, sealing relationship thereto, in which the flange hub ends each have a outwardly extending flange hub, wherein, the clamp has at least two clamp segments which are moveable from a closed, sealing, flange member retaining position to an open, unsealed, flange member liberating position. Said clamp segments engaging the flange members holding them together in the closed, sealing position, wherein clamp segment fastening devices can remotely forcefully open and close the clamp, wherein said clamp segment fastening devices comprise a redundancy of clamp segment conjoining elements. The clamp segment fastening devices can be remotely locked and unlocked.
