Steel Weld Neck Flange DN80 PN160 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN80 PN160 is a critical component for the safe operation of various trunk lines, ranging from oil and gas pipelines to water and heat supply systems. It has a diameter of 80 mm and withstands pressures up to 160 bar, ensuring system integrity under a wide range of operating conditions and loads. The temperature range of operation is -40°C to +450°C. Flatness control, proper bolt tightening, and gasket selection ensure stable, leak-free connections throughout the service life.

The manufacturing process begins with selecting certified St20 (C20 / S235JRG2) steel according to GOST 12820-80 and EN1092-1. Blanks are formed through hot stamping and forging to maximize metal density and eliminate defects. Mechanical processing on modern CNC equipment enhances dimensional accuracy and sealing surface quality. These flanges are used in industrial pipelines requiring increased reliability and resistance to high pressures.
