Why are flexible connections added to the liquid inlet and outlet of the methanol tank?
Flexible connections are added to prevent tank settlement from damaging pipelines or equipment.
Thermal expansion and contraction of the pipe will deform, produce stress, and break. The oil tank and the oil inlet and outlet combined pipe are also flexibly connected.
Most of the storage tank inlet and outlet pipelines in oil depots and other units have flexible connections. The main purpose is to prevent foundation settlement and damage to the connection between the storage tank and the pipeline!
That’s right! The purpose of adding flexible hose connections is to prevent tank settlement from damaging the pipeline and causing leakage. In the design of the tank farm, almost all inlets and outlets must be connected with hoses.
Are there any without flexible connections?
In order to resist earthquakes and prevent the settlement of the tank foundation, its design selection can be found in: Standard SY-4 4073-94 for the selection of metal hoses and corrugated compensators for anti-seismic storage tanks
It is a specification requirement to add flexible connections to the pipes in front of the storage tank to solve the problem of tank settlement. It’s not just a problem with methanol storage tanks.
Comparing the advantages and disadvantages of flexible connections and steel pipe connections, we can conclude that not only the methanol tanks, but also the outlets of our company's new normal pressure tanks are all soft connections.
Not only methanol tanks, but also general storage tanks are equipped with flexible joints at their inlets and outlets.
