ASTM A387 GRADE 22 Class 1 PVQ Plates

ASTM A387 GRADE 22 Class 1

We supply plates to global fabricators serving the oil, gas and petrochemical industry. 

These industries require a pressure vessel grade steel which works well in elevated temperatures and our material serves this purpose well. And with good corrosion and oxidation resistance, A387 Grade 22 Class 1 plates are a good option for sour gas environments too.
