i am looking for the test pressure of 6 " pipe line sch 40 inservice

mohamed-san,

your q is confusing!!!

anyway, hope this helps!!!

ask for the the line designation table from your company's process department. it is indicated there. with the type of test media to used...( air or water or others)..... if u don't have any,... try 1.5 of operating pressure of your 6"line as maximum..
