Steel Weld Neck Flange DN350 PN63 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN350 PN63 is designed to provide maximum tightness of flange connections under conditions of critical pressure and aggressive media. This piping element has a nominal bore of 350 mm and is rated at 63 bar, making it suitable for leak-tight and reliable systems in the chemical and oil and gas industries.

The collar flanges are manufactured from steel St20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1 using hot forging, ensuring high strength and metal density. After forming, the products are machined on CNC machines to achieve precise dimensions and surface roughness.

These flanges are applicable in power and heat supply pipelines, operating within a wide temperature range of -40°C to +450°C. Mounting includes collar welding, bolting with tightening control, and the use of spiral wound gaskets with protruding or flat surfaces for a durable, tight connection.
