Dear Members,

In one of my vessel (Air Receiver - SA 36), client data is no RT required and joint efficiency shall be 70%.
In the above case, can i use a value of 0.7 for 'E' in the required thickness calculation.

Also as per table UW-12 of div-1, the joint efficiencies for 'no RT' category is 0.7, 0.5 & 0.6.
Shell thickness is 8mm (sa 36) only.

Kindly give your valuable suggestions.


Regards
Wgsh
