Steel Weld Neck Flange DN80 PN10 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN80 PN10 from steel St20 (C20 / S235JRG2) is designed for reliable attachment of valves and equipment to pipelines. It features a nominal bore of 80 mm and can withstand a nominal pressure of up to 10 bar, demonstrating high resistance to loads, corrosion, and temperature fluctuations.

Quality control for these collar flanges, manufactured according to GOST 12820-80 and EN1092-1, is implemented at every stage, from raw material selection to final hydro testing. Modern hot forging and forging technologies ensure optimal metal structure and product durability for high-pressure systems.

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

These flanges are available for wholesale and retail purchase with self-pickup options in Krakow, Warsaw, Poznan, Lodz, Sofia, Varna, and Plovdiv. Wholesale buyers benefit from a discount system. Delivery for orders weighing one ton or more is available in Zary, Glogów, Legnica, and Opole. Delivery assistance is also available throughout Europe.
