For the pipeline with pressure, the easiest problem in the production process is the leakage at the connection flange. Once leakage is found, do not tighten the bolt under pressure. There are some reasons for the leakage in the process of operation, such as gasket damage, pipeline under thermal stress, etc. At this time, the problem can't be solved only by twisting the bolt, and often screw the Bolt hard because the leakage has not been eliminated until the bolt is broken and the high pressure gas in the pipe sprays out, causing injury accidents. There have been several factories which have suffered from the accident of Bolt fracture caused by the screw bolt with pressure and the casualty of flange plate flying out. Therefore, it is necessary to strictly abide by the regulation that the screw bolts with pressure are not allowed, and it is not allowed to hold fluke mentality and violate the operation regulations in order to seize time and catch up with tasks.
