démontage, vérification/remplacement des boulons d'un pipeline en activité/service

"hot" n'a rien à voir avec la chaleur. Le chauffage des boulons d'un pipeline de gaz en service est formellement interdite.

"hot" = pipeline en service .

"Note: Bolt cutting by any hot methods, including burning and grinding, is not usually permitted during hot bolting operations. Any cold bolt cutting, including hydraulic nut splitting, is usually only permitted by specific approval of the relevant Technical Authority
...
After all the bolts have been replaced, a final tightness check shall be carried out again using the specific operator’s sequence for hot bolting"

"Hot bolting refers to tightening a flange while it is in service. It is used to stop small stable leaks or as a preventive measure in high temperature or cyclic services. "High temperature" in this case may be defined as over 800°F (427°C). A cyclic service is one where the operating temperature changes by more than 300°F (149°C) in less than 30 minutes."
