Steel Weld Neck Flange DN20 PN16 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN20 PN16 is an indispensable component for creating split connections on pipelines, especially under high loads and with aggressive media. With an internal diameter of 20 mm and designed for a nominal pressure of 16 bar, this flange ensures stable operation in demanding industrial systems and transportation of various media.

These collar flanges are manufactured from high-quality St20 (C20 / S235JRG2) sheet or round steel, meeting GOST 12820-80 and EN1092-1 standards. Hot forging and forging technology creates an optimal fine-grained metal structure, increasing corrosion and wear resistance. This GOST production guarantees flange durability and safety.

Suitable for power and heat supply pipelines, these flanges operate within a wide temperature range of -40°C to +450°C. Installation involves collar welding, bolted fastening with controlled tightening, and the use of spiral wound gaskets with protruding or flat surfaces for a durable, tight seal.
