All devices are inspected every few years

Now the inspection interval for these devices has been changed to once every three years, but there are many problems with the materials used for the devices and pipelines; the equipment is not reliable at all, and the pipelines start leaking after a short time. There are various types of leaks, and I really don’t know how to get through three years under such conditions. I wonder what’s the situation for everyone else?
It’s all a major overhaul once a year; planning for the maintenance begins in April or May each year, and it is usually completed by September in the north
Many of them are held once a year; it depends on the specific circumstances. It seems that in the north, they are usually held in autumn, so that one can spend the winter peacefully after the repairs are completed
CNPC and Sinopec generally conduct repairs every two or three years, while local refineries carry out repairs annually.
We conduct a major repair every three years, and minor repairs each year
We carry out planned maintenance once a year, usually in October. After the maintenance, we prepare to spend the winter peacefully, but it’s possible that equipment issues may force us to suspend operations
We carry out minor repairs once a year; the device has been in use for over 2 years without any major repairs
Our factory conducts maintenance once a year; the equipment is over a decade old.
We also conduct a major repair every three years and a minor repair every year
It was overhauled in 2010; no overhaul is planned for 2012, so it can be considered to have followed the three-year maintenance schedule.
