BACKING STRIP CALCULATION
BACKING STRIP CALCULATION
(OP)
Dear all,
I have a question about the calculation of the backing strip. TEMA indicates that the equation in order to calculate the thickness of the backing device is: type A T=SQRT(WHY/BS) A and for type B T=SQRT(2WHY/BS). My case is configuration Type B according TEMA.
The question is that in 2.9 of APPENDIX 2 ASME VIII DIV1 explain that for a split loose flanges you have to consider 200% of the moment, so i understand that i have to consider 200% of the moment.
I would like to know what i have to do.
Thanks in advance.

Also, please refer to it as a backing ring. A backing strip goes behind a weld.

But when i use type A, why it's not necessary multiplier "2".
