Almost any pipeline implies the presence of shut-off valves in its structural scheme. It is especially important there where technical transfer is carried out:
- Natural or other fuels, as well as liquefied gas.
- Oil and oil products, both at the refineries themselves and for delivery to the consumer over long distances.
Inspection, maintenance and scheduled replacement of valves are carried out in accordance with the manufacturer's regulations and operating conditions (for example, areas of the Far North or Siberian regions).
Classification of valves
Stop valves for oil and gas pipelines are classified according to their design depending on the technological tasks that it must perform during operation, for example, they are distinguished:
- Gate valves are the simplest and most reliable devices for shutting off the working flow.
- Swing check valves - automatically shut off the flow in the event of a vacuum in the pipeline and thus exclude its reverse movement.
- Switching devices are installed in places of the pipeline system where it is possible to disconnect the safety valve and redirect the working flow along the backup branch.
- Spring-loaded safety valves - installed in tanks and automatically relieve critical pressure that occurs in them.
