PROBLEM TO BE SOLVED: To provide a flange cure plate for preventing loss of disassembly or cure tape for equipment or piping or erroneous selection of a gasket in a regular inspection work performed at a petrochemical complex.SOLUTION: A flange cure plate 1 that is manufactured by coinciding a transparent plastic sheet under its standards for flange and has both standards and sizes written has a structure in which more than two bolt holes are set such that a bolt cannot be passed there and no work can be carried out unless the cure plate is removed. In order to prevent erroneous selection of a gasket, both sizes and standards are indicated together. In order to confirm a difference between JIS standards and JPI standards related to the device by visual inspection, the cure plate is identified by colors. Making the flange cure plate 1 transparent enables confirmation about the flange sheet surface and the inside part to be confirmed without removing the flange cure plate 1. |
