The major overhauls of the equipment mainly involve the inspection of pipelines and pressure vessels. I’m not sure exactly what tasks are involved ?

Our facility is about to stop operating for maintenance, and I’ve been assigned to tasks related to the inspection of pressure pipelines and pressure vessels. This is my first time handling such work, so I would like to ask fellow colleagues for advice on what exactly needs to be done and what aspects require special attention Thank you!
Check if there are any leaks or rust: lol
Pay special attention to the following points: Check whether there are any devices or valves that have reached the end of their useful life; if so, replacement should be considered. If they continue to be used, they must comply with **relevant regulations**； Is there any damage? ； Has it been leaked? ； Is there any blockage? ； Remove residues ； Check whether the rusted area affects the sealing surface or the equipment surface; if so, repair or replacement must be considered ； Whether the sealing element is functioning properly and whether it needs to be replaced ； Check whether there are any abnormalities in the device’s recent operation records; if so, it needs to be inspected and repaired. Wait, wait, wait. That’s about all I know
The inspection by a professional or self-inspection of the three main safety accessories refers primarily to the safety valve and pressure gauge； Dismantle and clean the heat exchange equipment, then conduct pressure testing ； Inspection of installation, commissioning and testing of pressure pipelines and vessels undergoing technical renovation ； Inspection of pressure vessels and pipelines after maintenance, etc
1. The specific operation of pressure vessels shall comply with the \"Rules for Periodic Inspection of Pressure Vessels\"； 2. The specific operations for pressure pipelines are carried out in accordance with the \"Regulations for Periodic Inspection of In-service Industrial Pipelines\".
The overhaul plan seems rather general and not detailed enough
