Steel necked welding flange DN20 PN16/40 EN1092-1 P245GH/P250GH 911400026 S25AS

Robust connection in industrial installations

This steel neck flange, designed for welding, is a reliable element for connecting pipes with a diameter of DN20. Made of high-quality P245GH/P250GH steel, it meets the requirements of EN1092-1 and ensures a safe and durable connection in systems with a pressure of PN16 and PN40. It is a key component in the construction of industrial installations where reliability and resistance to operating conditions are a priority.

Design and application

The flange is characterized by a neck design, which means it has an elongated cylindrical part (neck) at the welding point with the pipe. This construction minimizes stress in the weld area, increasing the strength and safety of the connection. It is ideal for connecting elements in systems transporting liquids or gases under pressure. Its versatility makes it applicable in various industries – from chemical and petrochemical to energy and construction.

Material and standards

P245GH/P250GH steel is a grade of carbon steel with good weldability and mechanical properties. It allows for the creation of solid welds without the need for additional heat treatment. Compliance with EN1092-1 guarantees conformity with European quality and safety standards. The weight of the flange is 1.09 kg, and its dimension is 26.9 mm – these data are important in the design and installation of installations. The flange is not intended for soldering or crimping; its assembly is carried out exclusively by welding.
