Steel neck flange for welding DN80 PN16 EN1092-1 P245GH/P250GH 911160088 S25AS

Professional solution for steel installations

The steel neck flange for welding DN80 PN16 is a key component of pipeline systems requiring a durable and leak-proof connection. Manufactured in accordance with the EN1092-1 standard from P245GH/P250GH steel, it operates at a nominal pressure of 16 bar. The Geldbach brand product (catalog no. 911160088 S25AS) is used in the RES, HVAC, industrial automation, and oil and gas industries.

High-quality construction and materials

The flange body is made of certified P245GH/P250GH steel, characterized by high mechanical strength and corrosion resistance. The neck design allows for precise fit to pipes with a nominal diameter of DN80 (88.9 mm), guaranteeing connection stability. The weight of the component is 3.92 kg, which demonstrates a solid construction while maintaining optimal mounting parameters.

The P245GH/P250GH material exhibits good weldability and stability within the operating temperature range typical for industrial installations.

Operating parameters and compliance with standards

The flange operates at a nominal pressure of PN16 (16 bar) and temperatures adapted to the properties of the P245GH/P250GH material. Compliance with the European standard EN1092-1 ensures standard dimensions and tolerances for steel flanges. The component is neither threaded nor brazed - it is intended exclusively for permanent welding using welding methods.

The outer diameter of 88.9 mm enables standard connections in industrial installations, and the neck design ensures even stress distribution at the joint.

Installation and operation

Welding the flange is performed using welding methods adapted to P245GH/P250GH carbon steel. The welded connection creates a durable bond of elements resistant to vibrations and changes in working pressure. The welded connection guarantees system tightness and long-term operational reliability.

The product is delivered ready for installation without additional surface treatment. It is recommended to use standard welding procedures for structural steel and to perform weld quality control in accordance with applicable industry standards.
