EN 1092-1 Type 01 S235JR plate flanges are the most common solution for non-pressure applications and general utility piping. As a structural-grade carbon steel, S235JR offers excellent machinability and weldability at a lower price point than pressure-vessel grades. These flat-ring flanges are slipped over the pipe and fillet welded, providing a reliable connection for water treatment, HVAC, and low-pressure irrigation. They are the go-to standard for industrial projects where cost-efficiency is a priority.
