Dear Sir

 

Please find the below for Blind flange attachments calculation.

Refer ASME Sec V111 Div -1 UG -34.

UG-34 UNSTAYED FLAT HEADS AND COVERS

The minimum thickness of unstayed flat heads,

cover plates and blind flanges shall conform to the requirements

given in this paragraph. These requirements apply to both circular and noncircular

20 heads and covers. 

The minimum required thickness of flat unstayed circular heads, covers and blind flanges shall be calculated by the following formula

t=p d CP / SE
