HAK-Pİ Flat Flange PN25-40 DN65
High-pressure sealing reliability for demanding industrial pipelines.
HAK-Pİ Flat Flange DN65 provides a reliable, leak-tight connection for high-pressure industrial lines. In addition, this flange, manufactured from carbon steel, fully complies with EN 1092-1 and ISO 7005 standards. Therefore, it is a preferred choice in petrochemical and energy facilities, where it is treated with protective paint or galvanic coating for long service life.
The bolted connection type simplifies assembly and maintenance operations. Moreover, it operates within a temperature range of -10°C to +120°C, depending on the gasket. Fixed with 4 pieces of M16 bolts, the structure withstands PN40 (40 bar) pressure. As a result, system sealing is maintained at a high level.
HAK-Pİ Flat Flange DN65 — Technical Specifications
This flange is used across a wide range of applications, including petrochemical refineries, water treatment plants, fire extinguishing systems, and power plants. In particular, it provides leak-tight connections in high-pressure steam and process lines. Furthermore, the option to mount with spiral-wound or rubber gaskets successfully meets system pressure requirements. Additionally, its corrosion resistance reduces maintenance costs.
