Steel Weld Neck Flange DN500 PN16, made in accordance with GOST 12820-80 and EN1092-1, ensures perfect joint tightness. With a nominal bore of 500 mm and a maximum nominal pressure rating of 16 bar, this collar flange is ideal for demanding industrial systems, energy, oil refining and urban infrastructures. Flanges are widely used in ventilation complexes and air supply systems where hygienic standards and vibration resistance are important. Their operation at temperatures from -30 to +300 °C ensures versatility of use. Installation includes collar welding and bolted connection with uniform tightening, guaranteeing perfect alignment and repeated dismantling while maintaining tightness.

The technology of manufacturing collar flanges from steel St20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1 involves the use of hot forging and forging, providing high strength and density of the metal. After forming, the products are machined on CNC machines to achieve precise dimensions and surface roughness.
