Steel Weld Neck Flange DN100 PN10, made in accordance with GOST 12820-80 and EN1092-1, ensures perfect joint tightness. With a nominal bore of 100 mm and a maximum nominal pressure rating of 10 bar, this collar flange is ideal for demanding industrial systems in energy, oil refining, and urban infrastructure.

The manufacturing process of these collar flanges from steel St20 (C20 / S235JRG2) follows GOST 12820-80 and EN1092-1 standards, utilizing hot forging to ensure high strength and metal density. CNC machining further refines the product, achieving precise dimensions and surface roughness.

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