【In-depth Discussion on HaiChuan Modular Installation】Does the overall installation of a 18-meter-high flare count as modular construction?
Thread Content
In chemical plants, large flares are often lifted into place after the entire ground structure has been assembled, or they are assembled in sections and then put together in the air. Does the overall installation of large flares constitute modular construction?

It can be considered a relatively simple modular installation, with the structure, manufacturing processes, and equipment all integrated into modules; it’s likely that the electrical and control systems will need to be added later.

Due to the high costs associated with it (double-crane lifting + tail sliding, as well as the increased weight of the flare structure), overall lifting is being used less and less by installation companies.
Question: What are the differences in the structural connections of the torch between the 4th and 5th floors?
All the work, including electrical and instrumentation tasks as well as insulation work, is carried out on the ground; this is essentially similar to the process of installing components on the tower, and it cannot be considered modular construction.
The insulated floor is ready. The cable needs to be threaded layer by layer in the last step. The PLC is a floor-mounted skid.
The ignition system and the fuel gas pressure regulation skid are quite simple skids. Large torches indeed cannot have their electrical and instrumentation components installed all at once; small torches, on the other hand, can be completed right away, with sufficient length of cable left for installation on site. Our jacks all have cable slack.
