HP Well-head line Material Spec

Dear friends,

I need clarification for material specification in HP diesel injection line.
As per piping specification, downhole diesel injection line (H.P line) is of API CLASS 5000. The piping & fitting material is ASTM-A519 GR4130 & flanges are of API 6A- ASTM A-694-F60 We are not getting the correct consumables for this piping class . So we are working on substitution of this material with other which can withstand 345 bar pressure AT 1000 C.

So can I use A-106 GRB Piping with higher wall thickness which can withstand above design parameters. If yes how can I take care of fittings? So that I can match pipe & fitting ID. Also A-106 GR-B is having yield strength very less compared with A-519 GR-4130

Another solution is I can substitute with API-5L GR-X60 having the same yield strength as A-519 GR-4130 & also we are not having difficulty in getting consumables for the same.

  If anyone faces this kind of problem please let me know.

Appreciate your valuable time.
