Not all pipeline codes use MAOP.2- leak test pressure require for pipe is it related to design pressure or MAWP? You need to read the code to which your pipe refers.As said MAWP is normally a pressure vessel thing 3- what is mean MAWP of pipe is 1750PSI? Well it means the maximum pressure (other than test) is 1750 psis.Some context might help here.Maximum Pressure Rating Schedule 160,Schedule 40 and Maximum pressure ratings for pipes per.API 5L Carbon Steel Pipe and A-106,A-53,A333,A334.Minimum tensile strength 60 ksi (60000 psi).This table defines the maximum pressure rating for the specified industry standard pipes,Schedule 160,Schedule 40 and Schedule 80.Reference ANSI/ASME B36.10M-1995 Wrought Steel Pipe seamless and welded.Maximum Allowable Working Pressure Vs Design Pressure Design pressure is the maximum pressure that the system that can be exposed to and sets the system relief valve at the same pressure.This should be below MAWP and based on company standards can vary from 10% to 25% above the maximum operating pressure of the system.
