Why did a fire break out inside the pipeline while cutting away the abandoned circulating water pipeline? ?
Thread Content
The circulating water pipeline was removed a long time ago; it’s been about half a year since it was taken down. It was made of carbon steel and was stored in the factory’s waste pile. A few days ago, people planned to sell it as scrap metal, and they hired a welder to cut and dismantle the pipeline. However, during the gas-cutting process, combustion occurred inside the pipeline. I would like to ask experts why a circulating water pipeline that has been cut off and left unused for a long time could catch fire ? ? ? ? What are the substances that can cause combustion? ? ?
It might be some scaling, or the materials in the circulating water burning after drying
It might be the combustion of flammable substances in the scale
What substance in water reacts with iron to form a flammable material? What might be present in circulating water, and what are its combustion properties?
Is it possible that a biochemical reaction is taking place, producing flammable gases?
During the production process, flammable materials may mix into the circulating water; once the water in the pipes evaporates, only these materials remain, which can then cause a fire.
The analysis on the 9th floor makes a lot of sense! It is mostly due to materials from the production system flowing into the circulating water. Water evaporation left behind flammable materials. Only those who see the specific situation can analyze it correctly. It’s also possible that it’s the paint burning.
