Sorry for the late reply, been away for vacation. Thanks for all your reply and inputs. I will consider all your advice, need to reconfirm also the chloride content for SS materials, 50ppm is a bit high. The Designer also having a check for the test pressure of the systems, might be consider the...
Appreciate your reply Sir MickMc, i will follow your advise to check with process engineer, this is also the first time i encounter this situation. With regards to water ppm, it is specify in client specs that it must be less than 50ppm for 300 series stainless steel piping.
Sir EdStainless has a point, i review the client specs and found that the test pressure is calculated from flange pressure rating as per Table 2 of Asme B16.5 multiply by 1.5. In this case, the lowest component might be the Stainless steel flange. Now another question is, is it possible to...
Thanks for all your reply, the lines were separated with flanges but moving the pipe spools for placing the blind flange is not possible because of large diameter of pipe 36" and limited space as well. The test pressure difference for both materials is 7-bar so i assume no much issue on testing...
Hello! Sirs, newbie here..hoping to get advice from the professionals..is it possible to hydrotest different piping materials (LTCS, SS and Alloy 625 piping) at the same time using water with chloride content of less than 50ppm and with corrosion inhibitor? i am aware that it must be separate...
