Steel Weld Neck Flange DN20 PN40 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN20 PN40 is a key pipeline element, providing a highly reliable and tight connection. This fitting, with a 20 mm nominal bore and designed for nominal pressures up to 40 bar, is ideal for systems requiring high strength and durability, including industrial, municipal, and energy applications.

These collar flanges are manufactured from St20 (C20 / S235JRG2) steel according to GOST 12820-80 and EN1092-1 using hot forging, ensuring high strength and metal density. CNC machining after forming achieves precise dimensions and surface roughness.

Suitable applications include the chemical industry (with moderately aggressive media), industrial water supply, and compressed air systems. These flanges operate at temperatures from -40°C to +450°C, withstanding increased loads. Paronite or spiral wound gaskets are recommended for increased tightness.
