Steel Weld Neck Flange DN50 PN40 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN50 PN40 is designed to provide maximum tightness of flange connections under critical pressure and in aggressive environments. This piping element has a nominal bore of 50 mm and is rated at 40 bar, making it suitable for leak-tight and reliable systems in the chemical, oil, and gas industries. It provides high tightness and resistance to dynamic loads at temperatures from -40°C to +450°C. Spiral wound gaskets are recommended for maximum reliability in demanding conditions.

Blanks for these flanges undergo pre-treatment, including a specialized annealing process to relieve internal stresses from hot forging. The steel grade, St20 (C20 / S235JRG2), complies with GOST 12820-80 and EN1092-1, ensuring product quality and reliability. CNC machining guarantees dimensional accuracy and joint tightness.

These flanges are widely used for critical connections in the oil, gas, and metallurgical industries.
