What is the purpose of the removable short section in front of the equipment? How can it serve as a means to isolate devices?
Easy to disassemble, or the equipment requires core extraction. For example, with heat exchangers, it’s very inconvenient without removing the short circuits
In addition to maintenance, it may also be necessary to replace other components such as filters when space is needed
What you're referring to is not removing the short circuit, but using a substitute short circuit.
It is generally used for maintenance; the size of the short section to be removed is determined by the space required for removal
It is mainly for the convenience of maintenance, to make it easier to remove the equipment.
Maintenance is one aspect; there are also other devices to add, such as filters
As for the specific time required, is it to remove the short section and install a blind flange on the pipe end, thereby isolating the equipment? Additionally, the short section can be used, just like in heat exchangers, to be removed and thus create space for maintenance.
Some short circuits use flexible connectors; this is done first to facilitate installation and removal, and secondly to reduce the transmission of vibrations
