Pressure–temperature ratings are maximum allowable working gage pressures in bar units at the temperatures in degrees Celsius shown in Tables 2-1.1 through  2-3.19 for the applicable material and class designation.  Tables II-2-1.1 through II-2-3.19 of Mandatory  Appendix II list pressure–temperature ratings using psi  units for pressure at the t emperature in degrees  Fahrenheit. For intermediate temperatures, linear interpolation is permitted. Interpolation between class designations is not permitted.  

In BS EN 1092-1:2007, the materials and material groups used in the manufacture of flanges are given in Table 9 and their corresponding.Pressure/Temperature ratings are given in Annex G (normative). Additional materials that are widely in used in Europe are listed in Annex D (informative) but BS EN 1092-1:2007 contains no corresponding Pressure/Temperature information for these materials. National Annex NA (informative) contains guidance on Pressure/Temperature ratings for materials S235JR/1.0038 and ASME SA 105, which are predominantly used in the UK.1. Standard:EN1092-1 2.

The tabulated ratings for welding neck flanges areindependent of components to which they may be attached, and the pressure rating of the flange shall not be exceeded. Attachment welds should be made in accordance with the applicable code or regulation. See para. 6.7 and Figs. 1 through 3 for weld end dimensional requirements.1. Standard:EN1092-1 2.

The forging process of forged flange is generally composed of the following processes, i.e. selecting the process methods of cutting, heating, forming, cooling and forging after forging of high-quality steel billet, including free forging, die forging and fetal film forging. During production, different forging methods shall be selected according to the quality of forgings and the number of production batches1.
