A device for operation on a pressurized bolt connection between a first flanged tubular and a second flanged tubular

摘要

A device (1) for operation on a pressurized bolt connection (3) between a first flanged tubular (5) and a second flanged tubular (7). The device (1) comprises a first clamping member (20) with a first contact portion (32a) adapted to bear against the flange (12) of the first tubular (5), a second clamping member (22) with a second contact portion (32b) adapted to bear against the flange (12) of the second tubular (7), and a connection arrangement (25) for pulling the first clamping member (20) and second clamping member (22) together. The first contact portion (32a) and the second contact portion (32b) are adapted to bear at an inner part (35) of the flanges (12) between the bolts (8) of the bolt connection (3) and the body (10) of the two tubulars (5, 7).
