Steel Weld Neck Flange DN80 PN25 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN80 PN25, with its tapered collar, creates a strong butt-welded connection to the pipe. The 80 mm nominal bore and the ability to operate at 25 bar make this fitting optimal for high-pressure and critical lines, including industrial and power generation facilities.

These collar flanges, made of St20 steel (C20 / S235JRG2), are manufactured in accordance with GOST 12820-80 and EN1092-1. The manufacturing process includes complex technological stages from hot forging to precise CNC machining, ensuring high quality, compliance with GOST, and reliability for operation in difficult conditions.

Suitable applications include the chemical industry (moderately aggressive media), industrial water supply, and compressed air systems. These flanges operate at temperatures from -40 to +450 °C and withstand increased loads. The use of paronite or spiral wound gaskets is recommended to increase tightness.
