Steel neck flange for welding DN15 PN16/40 EN1092-1 P245GH/P250GH 911400021 S25AS

Welding Neck Steel Flange – Reliability and Durability of Connections

This welding neck steel flange is a key element in the construction of safe and efficient piping systems. The Geldbach product, manufactured in accordance with EN 1092-1 standard, ensures solid and leak-proof connections in industrial, heating and cooling systems. Its necked design facilitates welding, and the material – P245GH/P250GH steel – guarantees resistance to pressure and corrosion.

Features and practical application

This flange is characterized by a nominal diameter of DN15 and is suitable for operation at pressures up to PN16/40. The necked design of the flange allows for secure seating on the pipe before welding, which translates to higher quality and durability of the connection. This makes it ideal for applications requiring reliability, such as:

• Industrial installations – transport of media under pressure.
• Heating systems – connecting elements of boilers, radiators and pipelines.
• Cooling installations – ensuring the tightness of cooling circuits.
• Chemical and petrochemical industry – resistance to aggressive substances (depending on the additional protection used).

The weight of the flange is 0.768 kg, and its dimension is 21.3 mm – data important when planning installation and selecting appropriate tools. The lack of possibility of soldering or crimping means that this product is dedicated exclusively to welded connections.

Solid construction and compliance with standards

The flange is made of P245GH/P250GH steel, which ensures high mechanical strength and corrosion resistance. Compliance with the EN 1092-1 standard guarantees its safety and reliability in use. By choosing this product, you gain confidence that it meets all required quality standards. Additionally, the lack of thread eliminates the risk of loosening the connection due to vibrations or temperature changes.
