API 5L X65 PSL2 welding electrode and rod

[Khandaker Imamul Hasan]

Dear experts,

We have pipe line(under ground) having material API 5L X65 PSL2, dia.20"X15.09mm, which filler wire for GTAW and low hydrogen electrode for SMAW is best suited for this welding ?

Thanks in advance for your comments.

Hasan,

Best suitable Filler wire & electrodes are - GTAW - ER 70S2 & SMAW - E7018 D2.

Best of Luck

Regards,
M.K.Mubeen
QA Engineer

Dear mr Mubeen

Thanks for your reply. As the yield strength of Pipe is 65ksi may be can not use E70... series electrodes, it's yield strength is 58ksi. Could you check and confirm me again?

Dear Mr Dr. Georgios Dilintas

Good morning

With due respect.

this 70ksi is the Tensile strength of E7018 but Yield strength is 58ksi.

Our pipe API 5L X65 PSL2, its Yield strength is 65ksi and UTS is 77ksi.

please suggest a SMAW Electrode and GTAW filler metal for this.

Best Regards

Dear Hassan

 

Qualify your PQR with E7018 and check the tensile strength if the specimen breaks below the specified minimum tensile strength of the pipe material, the weld shell be set aside and new test weld shall be made with E 8018.

In Aramco we are using 7010-p1 in root and E8018-C3 for filling /capping for X65 pipes.

ER80SNi-1 and E8018-1 is a better option.

Thanks and Regards
