How to properly regulate fastening flange bolts

2018-05-10 16:00:24

In general mechanical operation, it will be found that the flange connection is easy to loose, or air leakage, and there are certain safety risks, but the light force tight bolts will not help, today to show you how to standardize the correct fastening flange bolts

Tools/Materials
1

Idle wrench Adjustable wrench

2

Flange a pair of matching stud bolts

Methods/Steps
1

First, prepare the tools needed to tighten the flange as shown in the figure, including wrenches (rigid wrenches and adjustable wrenches) bolts, flanges and other related tools

2

Secondly, place the gasket on the bolt to be tightened as shown in the figure, and then place the other flange on it smoothly, and the bolt holes should be aligned one by one. Be careful not to touch the flange after smooth placement.

3

Then the most important thing is to press the diagonal on the bolt, first fix the diagonal bolt with your bare hands until the flange can not shake, pay attention to ensure the correct position of the gasket at this time.

4

Then, use a wrench to strongly tighten the bolt until it cannot move, at this time pay attention to the Angle to tighten, one side tight, otherwise the other side will warp.

5

Then, the other diagonal bolt is also installed, and it is also tight diagonally, tightening one side to prevent warping the head.

6

Finally, tighten all bolts one by one in diagonal order to prevent loosening, and then add other connectors to ensure that the tight flange does not leak.

Matters needing attention
1

The bolts must be tight diagonally to prevent cocking

2

Wrenches are best matched with mechanical and adjustable wrenches for easy operation
