Subject: [MW:3238] Shelf life of Low hydrogen electrodes
Dear All
Our contractor has brought low hydrogen electrodes (E 7018 & 8018) which are manufactured in 2007 for welding station piping in one of our intermediate pump station of our cross country pipeline project. I would like to know whether these electrodes can be used now?. Is there any reference in ASME code regarding the expiry/ shelf life of Electrodes?
Please advise me in this regard.
Thanking you all in advance
Ravindra
Senior Project Engineer
