For pipelines that transport concentrated sulfuric acid from the tank area into the workshop, what piping arrangement is safer?
Thread Content
The idea now is to use the pipe racks inside the workshop, but it doesn’t seem very safe. I’m thinking of using the pipe racks on the outside wall of the workshop to get inside; I’m not sure which approach is better. I also hope that those with design experience will kindly share their insights
The corrosive effect of concentrated sulfuric acid is less severe than that of dilute sulfuric acid; if the material chosen is appropriate, the risk isn’t that high. It’s necessary to consider measures to prevent freezing in winter outside the workshop
The corrosive effect of concentrated sulfuric acid is relatively weaker than that of dilute sulfuric acid; if the material chosen is appropriate, the risk isn’t that high, and regular inspections during use will suffice
Concentrated sulfuric acid still possesses strong oxidizing properties. Even if it is routed overhead, it is recommended not to place it directly above pedestrian pathways on a regular basis. Additionally, due to its high concentration, care should be taken to prevent freezing in winter (by using heating elements)
Thank you for your help. We are in the southern region, so heat tracing is not required
I saw them go underground; they entered the workshop and then came up along the wall from underground
Buried installations are difficult to inspect for corrosion, and leakage incidents have occurred; it’s better to install them separately in unmanned areas
Agree with what was said on floor 7; overhead installation makes it easier to identify leakage points. Concentrated sulfuric acid is far less corrosive than dilute sulfuric acid; the typical leakage points in pipes are located at the flange connections. Proper selection of pipe material can prevent corrosion that could lead to pipe failure, and the correct choice of pipe pressure rating also plays a role in determining whether leaks will occur. Therefore, the focus remains on the flange connections
The concentrated sulfuric acid pipelines need to be protected from freezing! About to use! Collect. Currently, the sulfuric acid pipeline setup requires PN25, right?
