Discussion on storage tank piping issues?
Thread Content
The location and type of the first pipe rack near the tank interface, as described in the book, should enable the pipeline to effectively absorb the settlement of the tank foundation. ”May I ask how pipe racks are generally designed and what are their typical types?
One shouldn’t get too close; stay a bit farther away to allow sufficient deformation.
Generally, for large storage tanks where settlement needs to be taken into account, using spring supports alone to absorb the settlement amount is not sufficient； It is best to connect the tank outlet directly to a metal hose in order to absorb settlement; in this case, rigid supports can be used entirely
It should be done at the lowest point, then let the flexible metal hose absorb it
It is best to use a metal hose at the tank outlet, and then construct a concrete frame; the hose should be connected to the steel pipe flanges.
Hoses are generally used; for large tanks, larger tie rod bellows are employed. Steel supports are installed on the pipes near the storage tank to support the large valves and pipes. It is important that the foundation of these steel supports be placed on the foundation of the storage tank, so as to ensure they settle together with it.
