Pressure vessels and stacks anchor bolts torq

Pressure vessels and stacks anchor bolts torq

(OP)
Hello,

I want to know which is the torque value to be applied on the base anchor bolts of pressure vessels, process columns and stacks.

Can I simply use the torque values determined for bolts considering bolt diameter and material?

Some say the correct practice is tightening the nut by hand until it locks, then tighten it a quarter of round by tool (nut wrench), put on it a lock-nut and tight it by tool again. Is it correct?

Isn't this harmful to the concrete and grouting?

Thanks!

RE: Pressure vessels and stacks anchor bolts torq

Ask the design engineer of each vessel. In some cases, it may be desirable for the vessels to slide, in which case tightening the anchor bolts is counter-productive.
