Steel neck flange for welding DN125/133 PN16 EN1092-1 P245GH/P250GH 911160133 S25AS

Steel neck flange – a reliable connection in installations

The DN125/133 PN16 steel neck flange, manufactured according to EN1092-1 standard, is a key element in piping systems requiring a solid and tight connection. Designed for welding, it ensures durability and safety in media transmission. Made of high-quality P245GH/P250GH steel, it is characterized by corrosion resistance and high pressure resistance.

Design and application

This type of flange, also known as a neck flange type 11/B, has a characteristic shape with an elongated "neck" that increases the strength of the welded connection. The flange neck enters the pipe, providing a larger welding surface and minimizing the risk of cracks. It finds application in a wide range of industrial, water supply, heating installations and technological systems. It is ideal for connecting steel pipes with a nominal diameter of DN125 (corresponding to 133 mm).

Advantages and benefits

• Strength and safety: Made of P245GH/P250GH steel guarantees resistance to mechanical and thermal loads, ensuring long-lasting and safe operation.
• Tightness of connection: The neck design increases the welding surface, minimizing the risk of leaks and providing a hermetic connection.
• Compliance with standards: Meets the requirements of EN 1092-1 standard, which confirms its quality and safety of use.
• Versatility: Suitable for various media – water, gas, oil and other chemicals (compatibility of materials should be checked).
• Easy installation: Adapted for welding with standard methods, which facilitates and speeds up the installation process.
• Durability: Solid construction ensures a long service life even in difficult operating conditions.
• Weight: 6.3 kg – important information when planning transport and installation.
