Why are metal hoses used to connect the inlet and outlet of process storage tanks?

Metal hoses are used for connections mainly due to the following advantages: 1. Strong corrosion resistance: Metal hoses can be used in corrosive environments such as strong acids and strong bases, and they are not prone to corrosion. 2. Strong adaptability: Metal hoses can withstand high-temperature and high-pressure environments, as well as low-temperature and low-pressure conditions, meeting the requirements of inlet and outlet connections in various process tanks. 3. Good tightness: When the flexible metal hose is connected to a flange, its flexibility allows it to fit tightly against the flange’s sealing surface, ensuring reliable sealing. 4. Strong pressure resistance: Metal hoses are not easily flattened or deformed, and can withstand higher pressures and impacts. 5. Easy to disassemble: The metal hose features a simple connection method, making it easy to disassemble and maintain, which reduces maintenance costs and labor costs. Therefore, using metal hoses for connection is a very practical method for connecting the inlet and outlet of storage tanks. .

Generally, for tanks with a capacity of less than 100 cubic meters, metal pipes are used for the inlet and outlet connections, while for larger tanks, flexible metal hoses are employed for these connections in order to prevent stress in the pipes caused by the tank’s settlement

:Currently, emergency experts also recommend replacing the rigid pipes in hazardous storage tanks with flexible hoses, mainly due to the deformation caused by tank settlement.

It’s not necessary to use a hose connection; rather, a flexible connection should be used

Flexible connection to prevent settlement of the tank or pipeline foundation

Prevent stress caused by foundation settlement

Did you just write this randomly? Hoses for high temperature and high pressure, or low temperature and low pressure? Basically, it’s used in the chemical industry due to sedimentation reasons, yet none of those reasons were mentioned among all your points

My humble opinion: Use metal flexible connectors and spring brackets at the outlets to prevent normal settlement, not just to avoid tearing and leakage!
