[MW:3242] Re: Shelf life of Low hydrogen electrodes

There is no such conditions in code , but to avoid any quality issues or rejection ,you may check the electrodes for any damages of the coating and if there is no damages to the coating and no absorption of moisture ,just rebake the electrodes and use it. Verifiy if  there is some conditions put by client specifications or manufacturer.

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
