Steel Weld Neck Flange DN350 PN16 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN350 PN16 is a key pipeline element, providing a highly reliable and tight connection. This fitting, with a 350 mm nominal bore and designed for nominal pressures up to 16 bar, is ideal for systems demanding high strength and durability, including industrial, municipal, and energy applications. It is also suitable for systems with slightly aggressive media and low pressure, such as in agriculture, drainage, and non-critical chemical applications. The operating temperature range is -30°C to +300°C.

Flange billets undergo pre-treatment, including specialized annealing to relieve internal stresses from hot forging. The St20 (C20 / S235JRG2) steel grade complies with GOST 12820-80 and EN1092-1, ensuring product quality and reliability. CNC machining guarantees dimensional accuracy and joint tightness. The use of vapor or elastomeric gaskets with flat or protruding sealing surfaces simplifies installation and enhances reliability.
