Steel neck flange for welding DN65 PN6 EN1092-1 P245GH/P250GH 911060076 S25AS

Professional steel neck flange for demanding industrial applications

The steel neck flange for welding DN65 PN6 is a high-end installation component from the German brand Geldbach, designed to create durable and leak-proof connections in piping systems. Made of certified P245GH/P250GH steel, it meets the rigorous requirements of the EN1092-1 standard, ensuring compatibility with European installation systems.

Top-quality construction and materials

The flange is made of high-quality P245GH/P250GH steel, which is characterized by high corrosion resistance and excellent weldability. This material ensures long-term stability in high-temperature and high-pressure environments, while maintaining resistance to mechanical deformation.

The neck design allows for a precise fit to pipes with a nominal diameter of DN65, and the specially designed shape guarantees even stress distribution at the weld point.

Operating parameters and system compatibility

The flange is designed to operate at a nominal pressure of PN6 (6 bar), allowing its use in medium-pressure systems. The 76,1 mm dimension and a mass of 3,03 kg make it practical for transport and installation, while providing sufficient mass for connection stability.

The component is compatible with all piping systems that meet the requirements of the EN1092-1 standard and have a nominal diameter of DN65. The "transition connector" fitting type enables the creation of connections between different installation elements with varying characteristics.

Practical application and operational benefits

In the RES (Renewable Energy Sources) sector, the flange is used in the construction of photovoltaic and wind farms. In HVAC installations, the system allows for easy creation of branches and changes in pipe direction while maintaining full tightness.

In industrial automation, this component excels in technological process control systems. Installation via welding simplifies the installation design.

The flange is neither threaded nor brazed - its installation is carried out exclusively by welding, which guarantees maximum connection strength. The component is not suitable for press-fitting, which emphasizes its professional character intended for skilled installers.
