Steel Weld Neck Flange DN300 PN100 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN300 PN100 from steel St20 (C20 / S235JRG2) is designed for reliable attachment of valves and equipment to pipelines. It features a 300 mm nominal bore and can withstand nominal pressure up to 100 bar, demonstrating high resistance to loads, corrosion, and temperature fluctuations.

High-quality sheet or round steel grade St20 (C20 / S235JRG2), meeting the requirements of GOST 12820-80 and EN1092-1, is used in the manufacturing process. Hot forging and forging technology ensures an optimal fine-grained metal structure, increasing resistance to corrosion and wear. This GOST production guarantees flange durability and safety.

These flanges are designed for high-pressure pipelines in the oil and gas, chemical, and power industries, including high-pressure steam pipelines. They operate at temperatures from -70 to +450 °C. The use of spiral wound and metal gaskets with protrusion and recess surfaces (versions B, C, D) ensures maximum sealing reliability.
