Is it necessary to install a manual globe valve at the outlet of every pipe connected to the methanol storage tank equipment? What is the basis for this?
This reason should be sufficient to facilitate disconnection from the system. For example, damage to pipe welds and fittings, cracking, impact, wear, corrosion, and so on. If there is no root valve, when replacement or maintenance work is required, all the medium in the tank will be discharged. For reference.
The one at the bottom of the tank is understandable, but is it really necessary to have a root valve at the top as well? Moreover, the root valves are all located on the top of the tank, making operation quite troublesome
The main factors include stress deformation and external vibrations caused by the pipelines leading to them; as a result, the probability of damage is much higher than that at the bottom. For reference.
Not only manual valves, but also remote shut-off valves are required, independent of the SIS
