Black threaded flange DN20 PN16/40 EN1092-1 S235

The black threaded flange DN20 PN16/40 EN1092-1 S235 is a connecting element designed for water, sewage, and heating installations. Made of S235 structural steel, it operates in systems with a working pressure of up to 16 bar (PN16) and an increased pressure of up to 40 bar (PN40), in accordance with the requirements of the EN1092-1 standard.

Construction and materials

The flange body is made of S235 structural steel. Color: black.

The internal thread with a diameter of DN20 (26.9 mm) allows for a precise connection with pipes and other installation elements. The fitting type as a transition connector allows for adaptation to various pipe diameters. The product weight of 1.04 kg guarantees connection stability while maintaining compact dimensions.

Application and compatibility

The flange is used in hydraulic, heating, and sanitary installations. It is used when creating connections between steel pipes, cast iron pipes, and fitting elements. Thanks to compliance with the EN1092-1 standard, it ensures compatibility with European installation systems.

The product is not suitable for soldering or press-fitting, which means that assembly is carried out exclusively via threaded connections. This feature eliminates the risk of thermal damage to the material and allows for repeated disassembly without loss of technical parameters.

Operating parameters and safety

The flange operates in a wide temperature range typical for water and heating installations, maintaining full connection tightness at working pressures of PN16-PN40.

The thread dimensions of 26.9 mm correspond to the standard DN20 diameter, ensuring compatibility with installation systems according to the EN1092-1 standard.
