HAK-PI Weld Neck Flange PN25-40 DN125
Reliable, leak-tight connections for high-pressure and high-temperature pipelines.
HAK-PI Weld Neck Flange DN125 provides a reliable connection solution for heavy industrial conditions with its carbon steel construction. In addition, its DN125 nominal diameter and PN40 pressure class make it safe for petrochemical plants. Moreover, the weld neck design perfectly matches the pipeline and resists thermal expansion.
The carbon steel material promises long service life. Furthermore, this flange fully complies with EN 1092-1 and ISO 7005-1 standards. As a result, it operates across a wide temperature range from -10°C to +400°C, making it ideal for steam and natural gas lines. The symmetric bolt hole pattern simplifies installation and improves sealing performance.
