ASTM A193 B16 Blind Flanges

ASTM A193 B16 Blind Flanges are heavy-duty alloy steel flanges designed to close the end of piping systems operating under high temperature and pressure conditions. These flanges offer excellent strength, durability, and resistance to thermal stress, making them suitable for boilers, power plants, petrochemical pipelines, refineries, and high-temperature steam lines. Zeron Fasteners provides precision-engineered ASTM A193 B16 Blind Flanges that ensure leak-proof sealing and stable performance in critical industrial environments. Manufactured to global standards, these blind flanges are widely used for maintenance, testing, and temporary or permanent pipe closures.
