When it comes to fixing machinery, Han Yu is a professional.
But he'd never done a repair like today's before.
The inspection showed the fault wasn't too serious: the weld between the high‑pressure control valve's steam pressure sampling tube and its seat had cracked, causing steam leakage, and it had to be sealed off quickly.
Sealing it was simple enough, just weld it, but the steam's temperature is tied to the pressure.
At normal pressure, steam is at most 100 degrees Celsius, but what was leaking now was high‑pressure steam, over 200 degrees, and continuously at high temperature.
Han Yu couldn't believe the Superior hadn't equipped the officers and soldiers with thermal protective suits, let alone those balaclava‑style thermal hoods that make you look like a robber; all they had were Firefighting suits with poor thermal insulation, and they had to rush repairs in an engine room full of steam.
