API 5L X60 EQUIVALENT steel grades.

HI EVERYBODY!

I am working in hydropower pipeline.
The steel pipe is of standart API5L X60 but i'm having difficulties with Flanges because the most good manufacturers don't produce flanges with X60 and i want to know some equivalent grades with X60 steel for ordering the flanges.
If anyone can help me because is important for the welding process.

Albanbulku, Actually good manufactures produce flanges in grade F60. For diameters less 18" you can use also ASTM A 105 WN up to 900lbs (Ring Joint) and 18 inches and above, flanges per ASTM A694 grade F60, to match pipe wall thickness.

Rdgs.

Thnx. mate.

I have flanges from ASME B16.47 SERIES A WN,RS with DN700 class 150,100,68, But the seel pipe is from API 5L x60.
I am searching equivalent flanges material for welding with X60 steel.
