Steel Weld Neck Flange DN80 PN40 is designed to ensure maximum tightness of flange connections under conditions of critical pressure and aggressive media. This piping element has a nominal bore of 80 mm and is rated at 40 bar, making it suitable for leak-tight and reliable systems in the chemical and oil and gas industries.

The manufacturing process 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. Quality control at every stage ensures product reliability for high-pressure systems.

These flanges are used in industrial pipelines requiring increased reliability and resistance to high pressures. They operate within a temperature range of -40 to +450 °C. Flatness control, correct bolt tightening, and proper gasket selection ensure connection stability and tightness throughout their service life.
