Steel Weld Neck Flange DN400 PN16 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN400 PN16 is designed to provide maximum tightness of flange connections under conditions of critical pressure and aggressive media. This piping element has a nominal bore of 400 mm and is rated at 16 bar, making it suitable for leak-tight and reliable systems in the chemical and oil and gas industries.

Collar flanges are manufactured from carefully selected St20 (C20 / S235JRG2) steel conforming to GOST 12820-80 and EN1092-1. Blanks are formed using hot forging or forging methods, guaranteeing the absence of internal defects and ensuring high strength and durability.
