Casing installation sequence

What we want to show you in the moving video is the installation order of the casing.
Firstly ,side casing of double Main column with casing type shall be installed.
And then double girder type bottom casing is to be installed
The next step is to Install the top girder on the top.
This completes the assembly work of one block of HRSG Casing. After that repeat this process as designed.
HRSG is generally composed of 2 sets of TWO Double column with casing and a set of Single column without casing, and when this installation is completed, the non-column type casing is installed on the side and bottom to complete the first stage of Casing installation.
This corresponds to the first assembly of HRSG Casing, and adjustment work such as columns and casing welding work will be introduced in the next video.
