Hydrogen production steam generator
Thread Content
Our factory manufactures hydrogen conversion steam generators; it is possible that improper repair of the lining during maintenance led to the formation of a hot spot on its outer wall after it was put back into operation. Temperature measurements show that the temperature there is now 470°C. I heard from the manager that its material is something called 15 RoMo (that’s how the manager pronounced it; forgive me for not knowing how to write it). The allowable temperature is 420°C, and since we’ve already exceeded this temperature, we’re ready to stop operations at any moment. 15 What is molybdenum? Could it be that the manager meant 15 chromium-molybdenum, and misread the characters? Still. . . Also, has anyone encountered this situation? What should be noted!
What your leader should be referring to is 15CrMo.
It is very important to repair the lining of conversion steam generators; if not handled properly, operations have to be halted, and in more severe cases the generator must be replaced, which is quite troublesome. Some cases involve the formation of hot zones, while others feature circular hot zones – it is best to entrust such tasks to large companies with extensive experience in carrying out such work
Isn’t this supposed to read chromium-molybdenum? Why do so many people say it’s 15 molybdenum? The leader can’t be wrong, right?
It’s enough to know what it means; for example, proofreading – the proper term is \"jiaodui\", but most people call it *aodui*.
It is pronounced as ‘luo’ to distinguish it from metallic cadmium. 15CrMo belongs to medium-temperature hydrogen-resistant steel, and its operating temperature can reach 550°C. The occurrence of hot spot phenomenon may be due to improper installation methods of the lining, or the use of materials of insufficient quality, which leads to the peeling or cracking of the heat-resistant lining poured inside the tube box. The installation of this lining still needs to be carried out by a professional company
If the character used to represent “transformation” in your title is spelled incorrectly, there’s no need to worry about how it should be pronounced; it’s sufficient to know what it means. There are issues with the lining of the steam generator, so closer monitoring is needed; if the problems become severe, operations must be halted for repairs. There have been instances of bulging occurring in the past
You could tell that! Impressive!
Haha, did you really understand? Or has “I” understood?
