摘要： Provided are a nut type rotatable flange structure and a combination tool. Flanges of a first neck flange and a second neck flange are both arranged in a nut type rotatable flange collar, one of the flanges is secured by using a thread, and the other flange is secured by using jack bolts, so that the flanges of the first neck flange and the second neck flange are hermetically and stably fixed, instead of a method of aligning bolt holes in a flange with bolt holes in another flange and then screwing in bolts to achieve connection. In general, the nut type rotatable flange structure and the combination tool can achieve a hermetical connection between the flanges, with no need to use a conventional method of aligning a plurality of bolt holes to a plurality of bolt holes in flanges, which requires less mounting accuracy and improves operation convenience.
