Since your material is API 5L X65 you can try the following combination,
1. SMAW - E 8018 G (OK 74.70) from ESAB - Take it from Sweden plant.
2. SAW consumables from Lincoln Electric.
AWS Class F8A/P8 - E Ni5 - Ni5
Trade Names
P240 - Flux
LNS 165 - Wire
From the chemical composition you listed, the Carbon Equivalent value comes to around 0.38.
Preheat the joint around 100 Deg. C, Interpass 250 Deg.C Max.
Since your Diameters are 48" and 36" are you going to back chip from the inside to ensure complete penetration? If yes then you can use OK 74.70.
I you dont have access towards the root side of the weld joint, I will recommend you to use ER 70S 6 or ER 70S2 (GTAW), do not use cellulose electrodes for the root passes.
What ever consumable that has been mentioned above, please make sure that all of them meets the minimum specified properties of the base material (X65).
Both the SMAW and SAW conusmables mentioned above will definitely meet your requirement of X65 and for ER 70S 6 or ER 70S 2 you'll have to talk to the manufacturer / dealer.
Make sure you get conusmable TC batch tested (Both mechanical and chemical), do not accept batch TC's showing typical values.
Hope this helps,
Regards,
A.Praveen
