c) Regarding reinforcement of the opening: (i) Calculate the "missing" area A to be compensated for [C1.3.18.7.2] (ii) Sketch on A4, and include as part of the calculations (ie. not as a separate appendix), a cross section of the pipe going through the wall, with some reinforcing pad tentatively in position (D.R. Moss in "Pressure Vessel Design Manual" recommends the thickness of reinforcing pad to be between %&1% of the vessel wall thickness). Show relevant thickness Ty, t Tat. Ty (in actual mm) and areas A, etc as per Fig 3.18.10, also include a sketch showing weld dimensions t, E, B. & F, as defined in Fig 3.19.3 C (d) and determined from the legend accompanying this Figure. Take care with the differing definitions of "t's that may occur from section to section in A51210. (iii) Determine the limiting distances for reinforcement [Cl.3.18.10.2 and 3.18.10.3]. and then the available reinforcing area [Cl 3.18.10.4] in the wall (A1), in the branches (A2 & AS), and the welds (A4) and hence the cross sectional area (A5) of reinforcing pad required (if any). (iv) Determine the strength in tension (in Newtons) of the combination of all the elements contributing reinforcement to the shell, whose contribution can only be made if the welds holding them to the shell are adequate (ie those areas of reinforcing metal that are separate from the main vessel wall). (1) Determine the strength (in Newtons) of the welds on failure path (3)(3) on Fig 3.19.2(a) or if this path is not quite relevant for your case, then on the failure path associated with "letting go" the combined elements in (iv). Sketch the failure path as part of your calculations. Check that these welds' combined strength is adequate, i.e. not less than (iv). For allowed stress in weld types refer to C1.3.19.3.5 and 3.5.1.4.5 paragraph 2 c) Regarding reinforcement of the opening: (i) Calculate the "missing" area A to be compensated for [C1.3.18.7.2] (ii) Sketch on A4, and include as part of the calculations (ie. not as a separate appendix), a cross section of the pipe going through the wall, with some reinforcing pad tentatively in position (D.R.
