EN 1092-1 Type 05 PN16 blind flanges in S235JR are the standard choice for sealing piping systems in non-critical, low-pressure applications. As a structural-grade carbon steel, S235JR provides an economical solution for water treatment, HVAC, and general utility lines. These solid steel discs are bolted to the flange face to terminate flow, offering a secure, pressure-tight seal that is easily removed for system maintenance. They are favored for their excellent machinability and cost-efficiency in urban infrastructure.
