Issues with the bypass setting
Thread Content
Under what circumstances is it necessary to set up a bypass?
If the main route cannot affect normal production or safety, a bypass should be installed to keep the path open; for example, if a filter gets clogged, a bypass can be used. Bypasses are also provided for flow meters and control valves, serving as temporary routes during maintenance work.
Sometimes, heat exchangers also require bypasses, which facilitate temperature adjustment as well as maintenance. Regulating valves basically all have bypasses
The safety valves of some devices are also equipped with safeguards, primarily for emergency pressure relief. Typical self-regulating valves are equipped with bypasses so that maintenance can be carried out in case of problems with the valve without affecting normal production. The bypass is mainly for backup, for those parts that are prone to problems
Sometimes, to increase production, when opening the main valve to its maximum still does not suffice, a bypass is used to increase the flow rate.
The pipeline is equipped with vulnerable components (filters, pneumatic valves, electric heaters, etc.) to prevent failures during operation from affecting the proper functioning of the system； Alternatively, a bypass can be installed at points where the flow rate changes (suddenly increases) to regulate it.
