Hot bolting is a technique for replacing or re-tightening bolts on a flange connection while a pipe is still in use. It's also known as line bolting, single stud replacement, or bolt replacement.
Remove one bolt at a time from the flange
Relubricate the bolt
Reinstall the bolt or a new one
Retighten the bolt to a specified torque
Hot bolting is often used to replace corroded or degraded bolts while production continues. It can also be used to:
Reduce the workload during an upcoming shutdown
Enable the rapid breaking of flanges once the shutdown is in progress
Install the correct bolts without losing early production
Hot bolting is considered a high-risk activity and should only be done by experienced and qualified personnel. A thorough risk assessment and job safety analysis should be done before starting.
