JGC has been granted a patent for a fabrication method of a plant facility. The method involves fabricating modules at a fabrication yard, transporting them to the installation site, and adjusting the installation position and pipe spool positions to account for expansion and contraction caused by temperature differences. The modules are then connected to form the plant facility. GlobalData’s report on JGC gives a 360-degree view of the company including its patenting strategy. Buy the report here.

Modular fabrication method for plant facility with adjustable pipe spools
A recently granted patent (Publication Number: US11732963B2) describes a fabrication method for a plant facility used in fluid treatment. The method involves fabricating multiple modules at a separate fabrication yard, which includes pipe spools, frame structures, and hook up surfaces. The end portions of the pipe spools are positioned on the side surfaces of the frame structures, with some protruding from the hook up surfaces. These modules are designed to be coupled together horizontally to form the plant facility.
Once the modules are fabricated, they are transported to the installation site of the plant facility. Prior to transportation, the expansion and contraction amounts of the pipe spools caused by temperature differences between the fabrication yard and the installation site are calculated for each module. During installation, adjustments are made to ensure the modules are properly positioned and to compensate for the expansion and contraction of the pipe spools. This can involve adjusting the installation position of the modules with respect to the foundation and adjusting the position of the end portions of the pipe spools supported by the frame structures.
If the adjustment amount of the installation position exceeds a specified range, the position of the end portion of the pipe spool is adjusted. The adjustment amount is set to create a weldable gap of 3 mm to 6 mm between the end portion of a selected pipe spool and the end portion of the pipe spool to be connected. This adjustment is performed for some of the pipe spools other than the selected one.
In some cases, the position of the end portion of the pipe spool is adjusted on previously installed pipe spools of a module that was installed earlier at the site.
The fabrication method also includes the step of initially fabricating the entire plant facility at the fabrication yard and then dividing it into multiple modules.
This patent provides a detailed method for fabricating and installing a plant facility for fluid treatment. By calculating and compensating for the expansion and contraction of the pipe spools, the method ensures proper alignment and connection of the modules during installation. This approach can improve the efficiency and accuracy of plant facility construction, reducing the need for extensive on-site fabrication and adjustments.
