Discussion on Installation and Construction Issues of Low-temperature Gate Valves in Olefin Projects

In the construction of olefin plants, the design temperatures for pipes and equipment range from 1000°C to -254°C, and there are a wide variety of valves used to connect these equipment and pipes； This article conducts an in-depth exploration of the installation issues of double-plate low-temperature gate valves in projects (pressure relief holes on the valve plates). As required by the design specifications, low-temperature gate valves and ball valves that operate at temperatures below -29°C must have pressure relief channels to prevent abnormal pressure buildup in the valve body when it is closed. Low-temperature gate valves also vary according to different standards.
This is so confusing; does it mean one needs to follow the official account?
If they are from the same industry and understand project construction, this will be sufficient. Posting on the forum is too complicated
