Steel Weld Neck Flange DN40 PN6 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN40 PN6 is a universal solution for various industries requiring durable and reliable connections. This metal flange, designed for 40 mm pipes and systems with a nominal pressure of 6 bar, ensures long service life and compliance with modern safety and quality standards.

Production begins with careful selection of sheet or round billets of quality steel St20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1.

This process guarantees the high strength and durability of welded collar flanges, enabling operation under increased loads and meeting GOST requirements.

These flanges are used in industrial pipelines requiring increased reliability and resistance to high pressures. Their operational temperature range is -40°C to +450°C. Control of flatness, proper bolt tightening, and gasket selection ensure connection stability and tightness throughout their service life.
