What is the maximum size of internal/external floating roof tanks currently built in China?
Thread Content
I would like to know what the specifications and dimensions are of the largest internal floating roof storage tank currently built in China What medium to install? What about the largest external floating roof tank? Are there any other different pieces of information from abroad?
The largest external floating roof I’ve seen has a capacity of 150,000 cubic meters and dimensions of 100*21.2 meters; it is used for storing atmospheric pressure residue oil.
The limit for internal floating roofs is generally 50,000 cubic meters, as grid structures exceeding this volume present significant challenges; such roofs are mainly used for storing finished products or light oil. There are many external floating roofs with a capacity of 150,000 cubic meters, and these are primarily used for storing crude oil
Is it the truss structure that prevents the internal floating roof from being made larger? Doesn’t the ceiling of the gym seem bigger?
It seems that work is being done on a structure with a volume of 100,000 cubic meters. **There is still no standard for this; it’s different from stadiums. The roof of a stadium can be made of aluminum sheets or cladding, while for storage tank frameworks, steel plates are required. A framework of 50,000 cubic meters in size can weigh several hundred tons.**
The largest externally floating one seems to be 200,000 cubic meters at the moment.
Are there any applications? Where?
Five years ago, a 30,000-cubic-meter external floating roof tank was built, and three years ago a 100,000-cubic-meter external floating roof tank was constructed. I understand that the largest external floating roof tank in China has a capacity of 150,000 cubic meters; as for whether there are any tanks in China with a capacity of 200,000 cubic meters, I’m not sure……
It is said that the external floating roof costs 150,000, while the internal floating roof costs 50,000. The investment required for the roof of the gymnasium mentioned on the 4th floor is very high; in addition to the structural aspects, considerations regarding costs also need to be taken into account for external floating roof tanks. After all, building large external floating roof storage tanks is also aimed at saving on investment
I searched on Baidu and found that Maoming Petrochemical has 125,000 cubic meter external floating roof storage tanks, used for storing crude oil. 100,000 cubic meters is a large amount
External floating roof, 150,000; Tenglong Aromatics Terminal, for storing residue oil at atmospheric pressure； Internal floating roof, 50,000; Dalian Fujia, naphtha.
