[MW:22940] X70 API 5L "PSL2".

By Materials & Welding

Dear experts.

For pipeline construction, diameter 20 ", thickness 12.7mm and 20,62mm, as API 5L X70 steel" PSL2 "(attached image). We had considered making welding procedures (mechanical tests) SMAW process standard API 1104 with E8010- G.

Inspection (audit) requires us to accomplish with E9010-G, according to inspection (audit) E8010-G does not correspond to API 5L X70 "PSL2".

Please give me your opinion on this technique to determine further action.

Thanks and regards.
