I need to know about strength wise comparison of EFW and ERW pipes... which pipe to be used where?... Some where i studied that welded pipes have 25% lesser yeild strength than seamless pipes.. but i do nee comparison of ERW VS EFW.. thnx

With ERW pipe, all of the quality control and inspection in the world won't improve the Joint Efficiency Factor.
With EFW pipe, the Efficiency Factor can be improved up to 1.0 (100%) depending on the amount of additional radiography you specify above and beyond what is required per the pipe specification for your material.
For longitudinal bending stresses the Joint Efficiency is ignored.
