Steel Weld Neck Flange DN300 PN63 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN300 PN63, with its tapered collar, creates a strong butt welded connection to the pipe. The nominal bore of 300 mm and the ability to operate at 63 bar make this fitting optimal for high-pressure and critical lines, including industrial and energy facilities.

Production of these flanges includes multi-stage quality control, starting from the input control of the chemical composition of steel St20 (C20 / S235JRG2) and concluding with hydro-testing. All stages comply with GOST 12820-80 and EN1092-1, guaranteeing the reliability and durability of these metal flanges for high-pressure pipelines.

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 difficult conditions.
