Mechanical seal and external insulation for internal floating roof tanks
Thread Content
As shown in the diagram, I would like to ask the experts on this forum: Is it necessary to provide a secondary seal for internal floating roof storage tanks? Assuming that the owner insists on a secondary seal, are there any technical requirements for such a secondary seal? It would be ideal to have a technical specification sheet for the secondary sealing of an internal floating roof. PS: I’m really an amateur when it comes to insulation. . How is the insulation layer fixed? How do you determine the spacing of the fixed layers? My current level is very low: rock wool board + corrugated board! Seeking guidance
I was wrong; it’s as mentioned in the title. It’s just a simple question; no specific project is involved.
