Drawing of tube layouts is low productivity チューブレイアウトの描画は生産性が低いです。

• Layout resets• Baffles is not shown• Impingement is not

flexible• Limited tube

selection• Unable to store

permanently data

Problems Encountered

6

Tube layout drawing and HTRI model are inconsistent

Actual performance of HEx may differ from design

Problems Encountered

Why we need this improvement?

What is the target of this study? To increase productivity by reducing the

time in constructing/modifying tube layouts

To increase quality by automating data synchronization

9

WHY IS THE MES TUBELAYOUT TOOL LOW IN PRODUCTIVITYAND QUALITY?

ROOT CAUSE ANALYSISMANUAL SYNCHRONIZATION OF DATA BETWEEN CALCULATION AND DRAWING TOOLS

DISCREPANCY BETWEEN HTRI MODEL ANDTUBE LAYOUT

CONSTRUCTING/ MODIFYING OF TUBELAYOUT IS TIME-CONSUMING

CALCULATION AND TUBE LAYOUT TOOLS ARE SEPARATE SOFTWARES

CALCULATION AND TUBE LAYOUT TOOLS ARE SEPARATE SOFTWARES

Construction of tube layout 33 - 57

Modification

Increase size to 1.5x 67 - 83

Increase tubepass to 2x 77 - 88

Modify tubepass layout to mixed 76 - 83

Adjust OTL to 0.8x 80 - 91

Change to rod impingement 64 - 93

Change baffle cut 60 - 85

Adjust passlane location 69 - 91

Change baffle orientation 63 - 87

Increase inlet nozzle 66 - 88

The time in constructing a layout is reduced drastically
