Considerations for retightening high-pressure bolts at the top of tower equipment using a hammer
Thread Content
How is the vibration of the tower caused by hammering the high-pressure bolts at the top of the tower taken into account during the design of tower equipment?
Since it’s a high-pressure bolt, the wall thickness of the tower shouldn’t be too thin, right? Besides, it’s struck against a wrench rather than directly on the cylinder body, so there should be no problem, right? Is any special consideration needed?
However, the shaking of the tower that was felt during the operation of the hammer was very severe, which would exert considerable stress on the foundation or the welds at the bottom of the tower.
Why aren’t high-pressure bolts tightened with a torque wrench? Hydraulic torque wrenches offer accurate torque and high efficiency.
What is intended to be discussed here is the impact on existing older equipment.
