Questions about the “regular inspection” of high-temperature and high-pressure pipes in power plants?
Thread Content
How often should “periodic inspections” be carried out on the high-temperature and high-pressure pipes in power plants? What are the main inspection items (or test items)? Should it be a sample inspection, or should all items be inspected? Which department should conduct the inspection? What are the relevant **standards? I ask those with practical experience in this area to provide guidance! Thank you!
All four main pipelines are now considered part of the boiler itself. Internal inspections of the power plant are generally carried out every six years, and these inspections involve measuring thickness, hardness, using ultrasonic testing, and magnetic particle testing; the specific procedures follow those outlined for regular boiler inspections.
Such mandatory inspections are generally carried out by specialized equipment inspection agencies, and the inspection rate is usually based on random sampling
May I ask, what are the relevant **standards?
May I ask: are there any **standards in this regard?
Main steam, hot section, cold section, main feedwater
I still don’t understand what “hot section” and “cold section” mean
