Definition - What does Bypass mean?
Bypass is the combination of bypass valves and bypass line systems used in pipelines for transportation of crude oil, natural gas and petroleum products. Bypass Valve is a type of valve that is installed in a bypass pipeline. These valves generally do not indicate any particular category of valves, any particular shape or the size of the valve. Therefore, valves which are installed on the bypass piping line, such as pressure reducing valves, steam traps and control valves are also known as bypass valves.
Petropedia explains Bypass
When installing a bypass valve, understanding the purpose of laying down a bypass piping line is important. Thus an installation engineer should first understand the purpose of the bypass line before installing a bypass valve onto it. In the oil and gas industry applications, a bypass piping line is laid because of these two reasons:
- To act as a backup line so as to allow continuous operations of the industry in case any failure or damage occurs to the main pipeline equipment.
- To supplement the performance of the mainline valves.
