Steel Weld Neck Flange DN100 PN25 is a critical component for the safe operation of various trunk lines, ranging from oil and gas pipelines to water and heat supply systems. It has a 100 mm diameter and withstands pressures up to 25 bar, ensuring system integrity under a wide range of operating conditions and loads.

The manufacturing of these weld neck flanges adheres to GOST 12820-80 and EN1092-1 standards. Certified St20 (C20 / S235JRG2) steel and modern plasma-arc or laser cutting technologies ensure precise part geometry and minimal deformation. Rigorous quality control at every stage guarantees product reliability for high-pressure systems.

These flanges are widely used for critical connections in the oil and gas and metallurgical industries, providing high tightness and resistance to dynamic loads at temperatures from -40°C to +450°C. Spiral wound gaskets are recommended for maximum reliability in demanding conditions.
