Steel Weld Neck Flange DN40 PN16 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN40 PN16 is an indispensable component for creating split connections on pipelines, especially for high-load and aggressive media applications. This flange, with a 40 mm internal diameter and designed for 16 bar nominal pressure, ensures stable operation in demanding industrial systems and various media transport.

These collar flanges are manufactured from St20 steel (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1 standards. The manufacturing process involves multiple stages, from hot forging to precise CNC machining, guaranteeing high quality, GOST compliance, and operational reliability in challenging conditions.

These flanges are suitable for high-reliability industrial pipelines resistant to high pressures, operating within a temperature range of -40°C to +450°C. Controlled flatness, correct bolt tightening, and appropriate gasket selection ensure connection stability and tightness throughout the service life.
