Dear Expert,

Please note that the square or rectangular RF plate attachments in tank outer surface. Here the bracket support is taken form square or rectangular attachment to rest main pipe.

Kindly advise how to calculate the value of C1 multiplied by two for WRC 107/537 defines C1 as one-half of the full length of the attachment in the circumferential direction of the vessel. Please provide me example with some picture for easy understand of concept.

In view of above, the vessel or tank shell stresses can be ensured by WRC analysis with considering support loads.
