【Haichuan Equipment Guessing Game】Is this a submarine?
Thread Content
It has just been manufactured in the factory and is ready for shipment; at first glance, isn’t it just a submarine? It’s just that two more windows are open.

““Fractionating tower”…. which is the skirt base and which end?
It should be a horizontal storage tank, possibly with cement supports
It’s a horizontal vessel with a spherical head; its volume is considerable and the operating pressure is likely to be fairly high. It’s not clear why it’s used in that way. Is it better to use a spherical shape for storage tanks?
I met an expert; great. Spherical shapes take up a lot of space.
A real submarine has an elliptical conical shape. The image shows a U.S. Navy Virginia-class nuclear submarine leaving the factory.
Tianyi Petrochemical, a subsidiary of Ningbo Engineering Company, manufactured underground LPG covered storage tanks for BASF in Zhanjiang; the largest of these tanks has a capacity of 3500 m3, a diameter of 7.2 meters, and a weight of 710 tons； The smaller one has a volume of 1,750 m3, a diameter of 7.2 m, and a weight of 355 tons. Designed and manufactured in accordance with GB150 and EEMUA-190 standards.
It has a saddle; it’s likely a horizontal storage tank with a domed head. The pressure is considerable, so it’s probably an air storage tank designed for use at sea
