GOST-112821-80 PN6 Alloy Steel Welding Neck Flange

GOST-112821-80 PN6 Alloy Steel Welding Neck Flange introduction

GOST-112821-80 PN6 Alloy Steel Welding Neck Flange is designed to be joined to a piping system by butt welding. This kind of flange include lots of specification, but is preferred for high stress applications. The necks, or hubs, transmits stresses to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of Welding Neck flange matches bore of the pipeline, reducing turbulence and erosion.
