The issue of sealing pipelines passing through walls in crude oil pump rooms
Thread Content
I would like to ask the experts: in oil refinery crude oil pump rooms or other pump rooms, when pipelines pass through the walls of these rooms, is it necessary to seal the gaps between the walls? Are there any standards that govern such regulations?
To seal it, just fill it with polyurethane foam. If there’s no blockage, I clean thoroughly every day.
What I mean is, from a safety perspective, should we carry out blocking? Or are there any regulations that explicitly specify whether this must be sealed or not? I’d like to ask for advice
What was written above is incorrect; it should be between the pipe and the wall
I’m not familiar with safety regulations. I think the first thing is to create a space that is relatively isolated; that’s exactly what walls serve for – they help prevent fires from spreading. The second aspect is to stop toxic and harmful gases from entering the indoor space; again, walls play a role in isolation and blocking such substances. Therefore, it’s necessary to carry out sealing measures. Of course, the sealing materials should have flexible properties, such as polyurethane foam, polystyrene foam, polyethylene foam, etc. It’s best to avoid using cement for filling, as pipes vibrate during operation. After filling, apply paint or coating; the color of the paint should match that of the wall.
It is necessary. If no sealing is done, then what is the value of your factory building? It would be sufficient to simply build a shed. I agree with the view expressed on the 6th floor; you can refer to the relevant regulations on firewalls in sections 6.1.5 and 6.1.6 of GB 50016. I hope this helps you:P
It must be sealed, in accordance with relevant petrochemical regulations

The opinions expressed by all netizens are generally correct; safety in hazardous chemicals enterprises must be taken seriously. As for the citation standards mentioned by the original poster, 2 screenshots are provided for their reference. Specific standard document attachment: Figure 1 is taken from Attachment 1 ； Figure 2 is taken from the attachment. Additionally, attention must be paid to the problems that may arise from vibrations and stresses in the pump piping, and proper support and vibration damping measures should be implemented. When making openings in a wall, it is necessary to fully understand the wall’s load-bearing capacity. Feel free to ask other questions for us to discuss together. Progress together!
