Steel Weld Neck Flange DN40 PN25 S235JRG2 EN 1092-1

Steel Weld Neck Flange collar DN40 PN25 of steel St20 (C20 / S235JRG2) is designed for reliable connection of valves and equipment to pipelines. It features a 40 mm nominal bore and a pressure rating of 25 bar, offering high resistance to loads, corrosion, and temperature fluctuations.

These collar flanges, made of steel St20 (C20 / S235JRG2), are manufactured according to GOST 12820-80 and EN1092-1 standards using modern hot forging techniques. Plasma-arc and laser cutting equipment ensure high-quality cuts and precise geometry, crucial for tight connections at high pressures.

Suitable applications include chemical processing (moderately aggressive media), industrial water supply, and compressed air systems. The flanges operate within a temperature range of -40°C to +450°C and withstand elevated loads. Paronite or spiral wound gaskets are recommended for enhanced sealing.
