    selecting proper piping design temperature for HP service per Code

    Thank for for your posts. We have reviewed the ASME B31.1 Paragraph 302.2.4. Now people are fighting about what the design temperature of the piping should be. The first part of this addresses design pressure and design temperature. Some people are reading this as saying you can select a lower...

    selecting proper piping design temperature for HP service per Code

    What are the consequences if the line fails? >>>>the equipment is located within a safety paneled area, we have had failures of high pressure components in the past and the safety panels are no gaurentee to hold the pressure. A vapor and liquid stream would result, which the human eye could not...

    selecting proper piping design temperature for HP service per Code

    I am working on design for high pressure and high temperature process. The problem is defining the design temperature for a piece of piping between a high pressure (4300 psig design pressure) and high temperature (design 1100F) reactor and downstream exchanger (design temp 750F with design...
