Flat steel flange DN125/139 PN16 EN1092-1 S235 901160139 B37AS

Steel flat flange DN125/139 – a reliable connection in installations

This steel flat flange, with dimensions DN125/139 and pressure class PN16, is a solid element for connecting pipelines. Manufactured in accordance with EN1092-1 standard from high-quality S235 steel, it ensures durability and safety in demanding working conditions. The Geldbach brand is a guarantee of precision and reliability.

Construction and application

Thanks to its construction, this flange is ideal for connecting elements of steel installations. Its flat surface facilitates assembly and ensures a tight connection. It finds application in various systems, such as:

• Central heating, ventilation and air conditioning (HVAC) installations
• Renewable energy systems (RES), e.g. in solar or geothermal installations
• Industrial automation – wherever durable and safe pipeline connections are required.

The weight of the flange is 5.41 kg, and its dimension is 139.7 mm. It should be noted that the product is not threaded or soldered, which affects its assembly method – it requires appropriate gaskets and screws.

Material and standard

S235 steel is characterized by good weldability and impact resistance, which translates into a long service life of the connection. Compliance with EN1092-1 standard guarantees compatibility with other installation elements meeting this standard and ensures safety of use. Pressure class PN16 means permissible working pressure up to 16 bar – important when designing systems under load. The use of this type of flanges allows for the construction of safe and efficient installations, resistant to corrosion and mechanical damage.
