ASTM A420 WPL6 is the low-temperature counterpart to A234 WPB, covering wrought carbon steel butt-welding fittings impact tested at -46 degrees C. Fittings are normalised after forming and every heat is Charpy tested, so elbows, tees and reducers keep their ductility in cryogenic and sub-zero service alongside A333 Grade 6 pipe.
Sarovar Tube Industries manufactures, stocks and exports ASTM A420 WPL6 Pipe Fittings from Mumbai to customers across the Middle East, South East Asia, Europe, Africa and the Americas. Every heat is verified by in-house testing before despatch and supported by complete documentation, so the material you receive is exactly the material you specified.
