There are three common types of API flanges: API 2000,3000,5000 and there are two high pressure series, API 10,000 and 15,000. The number of the series indicated corresponds to the maximum working pressure expressed in psi at a temperature of l00ºF. This maximum working pressure is affected by temperature�The maximum working pressure of the flange will be reduced by a factor of 1.8% for each 50ºF increase in temperature above 100ºF to a maximum of 450’F. The following table gives the maximum working pressure as a function of temperature. [img]http://bp1.blogger.com/__lmqvG9CeQs/R0Z0Dp4DX1I/AAAAAAAAAP8/Vho_GCH6wZA/s400/flange+1.JPG[/img]
