Haihao Group Exports EN 1092-1 ASTM A516 GR70 Flanges to Vietnam
Haihao Group has proudly completed another international delivery – a batch of EN 1092-1 flanges supplied to a long-term partner in Vietnam. The order consists of Type 01 B1 plate flanges and Type 05 B1 blind flanges, all produced in accordance with EN 1092-1 and ASTM A516 Grade 70 standards.
Each flange was manufactured under strict process control to guarantee dimensional precision, mechanical integrity, and consistent material quality, ensuring reliable operation in critical industrial environments.
