Steel neck flange for welding DN40 PN16/40 EN1092-1 P245GH/P250GH 911400048 S25AS

Professional installation component for demanding systems

The DN40 PN16/40 steel neck welding flange represents a top-class solution for industrial installations requiring reliable and durable pipe connections. Made of P245GH/P250GH carbon steel in accordance with the EN1092-1 standard, it ensures exceptional mechanical strength and resistance to high pressures and operating temperatures.

Design and materials guaranteeing durability

At the heart of this flange is high-quality P245GH/P250GH carbon steel, which is characterized by excellent weldability and resistance to deformation under load. The special neck allows for a perfect fit to pipes with a nominal diameter of 48,3 mm, resulting in maximum connection tightness. The "transition connector" type design allows for a smooth transition between different installation elements, eliminating stress concentration points.

Applications in practical installation

This flange finds wide application in heating systems with high temperature parameters, where tightness is required at pressures up to 40 bar. It performs excellently in refrigeration installations and steam systems, where corrosion resistance and dimensional stability are crucial for operational safety. In industrial automation, it ensures reliable connections of sensors and measuring devices to main process lines.

Advantages of welding installation

The welding installation method eliminates the need for additional gaskets or threaded elements, significantly reducing the risk of leaks during operation. The welded connection creates a uniform metallic structure with high mechanical strength, resistant to vibrations and temperature changes characteristic of industrial working conditions. Such installation guarantees years of maintenance-free system operation while maintaining full tightness.

Operating parameters and system compatibility

The flange has been designed to operate at a nominal pressure of PN16/40, making it a universal solution for both low and medium-pressure systems. The nominal diameter DN40 (48,3 mm) ensures optimal medium flow while maintaining the compact dimensions of the entire component. A weight of 2,15 kg facilitates transport and installation without compromising the robustness of the construction.
