e) Refer to the Temperature/Pressure ratings table for steel flanges provided in Table 2.1 of A52129 and to the sample tables of flanges manufactured to A52129 provided in Chapter 6 Appendix 6D, and hence select an appropriately sized slip on plate flange, blind plate and associated bolts. Note that the slip on flange will have to be bored to suit your pipe's special outside diameter. This may weaken the flange a bit compared to the standard size and may reduce spanner room. The strength of your specially adapted flange and its associated bolts and cover plate are to be confirmed using the calculation methods in A51210, as outlined below.
