MSS SP-75 WPHY60 or A860 WPHY60 suit my needs, but I can not find any supplier for those fittings in Europe. They all offer TStE 420 according to DIN standards (delivery time is 6-7 months. I need those fittings in 2-3 months. Regards!
I am designing a low temperature pipeline for natural gas. I use A420 WPL6 for fitting dimensions up to 14 inch. For larger dimensions I need material suitable for low temperatures with yield strength - 60ksi (415 MPa).
What material should I use?
