The flare line fell
Thread Content
Recently, there was an accident in which a torch pipeline fell down in a company, which made people feel a little scared. Fortunately, there were no construction workers on site at night. It is initially thought to be a problem with the torch design and the specific cause is still under investigation.
When I hear these things happening, I can only pray secretly and strengthen my safety awareness. Chemical companies are inherently accident-prone places, and they are often accidental.
It sounds like the original poster meant what happened during the construction phase. Can you tell me more specifically?
Is it during the installation process? Can you explain it in detail? We are now installing the torch.
The flare line occurs when the system is operating and is caused by a flare vent due to a shift interlock accident. The on-site investigation found that there were a large number of crystals in the pipeline, and there were few separation tanks along the torch route. Restoration construction is now complete. It is known that another company also had a torch fall accident when the operation was stable. The reason was that the water was not drained in time. I hope this can remind everyone to strictly follow the process and add drainage facilities in a timely manner during torch construction to prevent such accidents from happening!
I'm really speechless when this happens. There has been an incident in ykgh where water accumulated in the pipeline caused the torch pipeline to collapse and fall off. However, due to the crystallization problem, it can also cause such serious consequences. I can really say that it is no wonder. You must know that the diameter of the torch pipe is more than 1 meter.
As far as I know, there are many such situations. First, a large chemical company in Inner Mongolia once experienced a situation where the entire vent pipeline vibrated violently until it collapsed. ； The reason is that the amount of shorting is too large. The vent pipeline was designed without considering the maximum vent volume in the chemical system accident state. Secondly, a coal chemical enterprise in Shandong also experienced a vent pipeline detachment accident. The reason was that the vented air contained water and caused excessive vibration. Finally, a chemical company in Yulin also had a vent pipeline explosion, resulting in a falling accident. The reason is that ammonium bicarbonate accumulates in the vent line, causing an explosion. ； I don’t know what the reason is for the original poster’s company? We can cool off and learn from each other * Discuss it!
As you said, the crystallization is severe.
If the venting speed is too fast and the venting pipe is overpressured, it may cause the venting pipe to crack.
While driving, the torch pipe contained a large amount of water and collapsed.
An accident occurred in our factory where the S25 and S07 steam pipelines fell entirely from the pipe gallery brackets. The key was that the fixed brackets and movable brackets were not carefully designed, and the thermal expansion displacement was not carefully designed.
