Steel neck flange for welding DN150/159 PN16 EN1092-1 P245GH/P250GH 911160159 S25AS

Robust construction and high corrosion resistance

The weld-on stub end steel flange, made of high-quality P245GH/P250GH steel, is a reliable solution for connecting pipelines in industrial systems and heating installations. Designed in accordance with EN1092-1 standard, it guarantees the safety and tightness of connections. Its solid construction ensures long-term operation even in demanding conditions.

This type of flange, designed for welding, is characterized by rigidity and resistance to mechanical loads. The flange neck provides a smooth transition between the pipe and the mounting element, minimizing the risk of turbulence and cavitation in the flowing medium. Made of P245GH/P250GH carbon steel, it is an economical choice for many applications.

Application and specification

The flange with a diameter of DN150/159 and a nominal pressure of PN16 finds application in a wide range of installations:

• Chemical industry: For connecting pipelines transporting aggressive media.
• Energy sector: In cooling and heating systems.
• Construction: In water and sewage systems and fire protection systems.
• Heating: For connecting elements of boilers and heating systems.

The weight of the flange is 7.81 kg, and its dimension is 159 mm. The inability to solder or crimp makes it a solution dedicated exclusively to welding – which ensures a durable and safe connection. It is important to properly prepare the surface before welding and to use qualified welders.
