Flange bolt installation steps


First prepare the tools needed to tighten the flange bolts, including wrenches (dull wrenches and adjustable wrenches) bolts, flanges and other related tools.


Next, place the gasket on the bolt, then place the other flange on top, and the bolt holes should be aligned one by one. Be careful not to touch the flanges when placed smoothly.


Then the most important thing is to press the diagonally on the upper bolt. First fix the diagonal bolts with bare hands until the flange can not shake. Pay attention to the correct position of the gasket.


Then, use a wrench to tighten the bolts vigorously until it stops. At this point, pay attention to the tightness of the corners, and tighten it on one side, otherwise the other side will be lifted.


Then, install the other diagonal bolts, the same diagonally tight, one side to prevent squatting.


Finally, tighten all the bolts in a diagonal order one by one to prevent loosening, and then add other connecting parts, so that the fastened flanges ensure no air leakage.
